This article explains how to identify holds placed on Exchange Online mailboxes in Microsoft 365.

Microsoft 365 offers several ways that your organization can prevent mailbox content from being permanently deleted. This allows your organization to retain content to meet compliance regulations or during legal and other types of investigations. Here's a list of the retention features (also called holds) in Office 365:

  • Litigation Hold: Holds that are applied to user mailboxes in Exchange Online.

  • eDiscovery hold: Holds that are associated with an eDiscovery case in the security and compliance center. eDiscovery holds can be applied to user mailboxes and to the corresponding mailbox for Microsoft 365 Groups and Microsoft Teams.

  • In-Place Hold: Holds that are applied to user mailboxes by using the In-Place eDiscovery & Hold tool in the Exchange admin center in Exchange Online.

  • Microsoft 365 retention policies: Can be configured to retain (or retain and then delete) content in user mailboxes in Exchange Online and in the corresponding mailbox for Microsoft 365 Groups and Microsoft Teams. You can also create a retention policy to retain Skype for Business Conversations, which are stored in user mailboxes.

    There are two types of Microsoft 365 retention policies that can be assigned to mailboxes.

    • Specific location retention policies: These are policies that are assigned to the content locations of specific users. You use the Get-Mailbox cmdlet in Exchange Online PowerShell to get information about retention policies assigned to specific mailboxes.

    • Organization-wide retention policies: These are policies that are assigned to all content locations in your organization. You use the Get-OrganizationConfig cmdlet in Exchange Online PowerShell to get information about organization-wide retention policies.For more information, see the 'Applying a retention policy to an entire organization or specific locations' section in Overview of Microsoft 365 retention policies.

  • Microsoft 365 retention labels: If a user applies a Microsoft 365 retention label (one that's configured to retain content or retain and then delete content) to any folder or item in their mailbox, a hold is placed on the mailbox as if the mailbox was placed on Litigation Hold or assigned to a Microsoft 365 retention policy. For more information, see the Identifying mailboxes on hold because a retention label has been applied to a folder or item section in this article.

To manage mailboxes on hold, you may have to identify the type of hold that's placed on a mailbox so that you can perform tasks such as changing the hold duration, temporarily or permanently removing the hold, or excluding a mailbox from a Microsoft 365 retention policy. In these cases, the first step is to identify the type of hold placed on the mailbox. And because multiple holds (and different types of holds) can be placed on a single mailbox, you have to identify all holds placed on a mailbox if you want to remove or change a hold.

Step 1: Obtain the GUID for holds placed on a mailbox

You can run the following two cmdlets in Exchange Online PowerShell to get the GUID of the holds that are placed on a mailbox. After you obtain a GUID, you use it to identify the specific hold in Step 2. A Litigation Hold isn't identified by a GUID. Litigation Holds are either enabled or disabled for a mailbox.

  • Get-Mailbox: Use this cmdlet to determine whether Litigation Hold is enabled for a mailbox and to get the GUIDs for eDiscovery holds, In-Place Holds, and Microsoft 365 retention policies that are specifically assigned to a mailbox. The output of this cmdlet will also indicate if a mailbox has been explicitly excluded from an organization-wide retention policy.

  • Get-OrganizationConfig: Use this cmdlet to get the GUIDs for organization-wide retention policies.

To connect to Exchange Online PowerShell, see Connect to Exchange Online PowerShell.

Get-Mailbox

Run the following command to get information about the holds and Microsoft 365 retention policies applied to a mailbox.

Tip

If there are too many values in the InPlaceHolds property and not all of them are displayed, you can run the Get-Mailbox <username> Select-Object -ExpandProperty InPlaceHolds command to display each GUID on a separate line.

The following table describes how to identify different types of holds based on the values in the InPlaceHolds property when you run the Get-Mailbox cmdlet.

Hold typeExample valueHow to identify the hold
Litigation HoldTrueLitigation Hold is enabled for a mailbox when the LitigationHoldEnabled property is set to True.

The InPlaceHolds property contains GUIDs of any specific location retention policy that's applied to the mailbox. You can identify retention policies because the GUID starts with the mbx or the skp prefix. The skp prefix indicates that the retention policy is applied to Skype for Business conversations in the user's mailbox.
Excluded from an organization-wide Microsoft 365 retention policy-mbxe9b52bf7ab3b46a286308ecb29624696If a mailbox is excluded from an organization-wide Microsoft 365 retention policy, the GUID for the retention policy the mailbox is excluded from is displayed in the InPlaceHolds property and is identified by the -mbx prefix.

Get-OrganizationConfig

If the InPlaceHolds property is empty when you run the Get-Mailbox cmdlet, there still may be one or more organization-wide Microsoft 365 retention policies applied to the mailbox. Run the following command in Exchange Online PowerShell to get a list of GUIDs for organization-wide Microsoft 365 retention policies.

Tip

If there are too many values in the InPlaceHolds property and not all of them are displayed, you can run the Get-OrganizationConfig Select-Object -ExpandProperty InPlaceHolds command to display each GUID on a separate line.

The following table describes the different types of organization-wide holds and how to identify each type based on the GUIDs contained in InPlaceHolds property when you run the Get-OrganizationConfig cmdlet.

Note channel messages are stored in the group mailbox that is associated with a Microsoft Team.

For more information retention policies applied to Microsoft Teams, see the 'Teams location' section Overview of retention policies.

Understanding the format of the InPlaceHolds value for retention policies

In addition to the prefix (mbx, skp, or grp) that identifies an item in the InPlaceHolds property as a Microsoft 365 retention policy, the value also contains a suffix that identifies the type of retention action that's configured for the policy. For example, the action suffix is highlighted in bold type in the following examples:

skp127d7cf1076947929bf136b7a2a8c36f:1

mbx7cfb30345d454ac0a989ab3041051209:2

Duration

The following table defines the three possible retention actions:

ValueDescription
1Indicates that the retention policy is configured to delete items. The policy doesn't retain items.
2Indicates that the retention policy is configured to hold items. The policy doesn't delete items after the retention period expires.
3Indicates that the retention policy is configured to hold items and then delete them after the retention period expires.

For more information about retention actions, see the 'Retaining content for a specific period of time' section in Overview of retention policies.

Step 2: Use the GUID to identify the hold

After you obtain the GUID for a hold that is applied to a mailbox, the next step is to use that GUID to identify the hold. The following sections show how to identify the name of the hold (and other information) by using the hold GUID.

eDiscovery holds

Run the following commands in Security & Compliance Center PowerShell to identify an eDiscovery hold that's applied to the mailbox. Use the GUID (not including the UniH prefix) for the eDiscovery hold that you identified in Step 1. The first command creates a variable that contains information about the hold. This variable is used in the other commands. The second command displays the name of the eDiscovery case the hold is associated with. The third command displays the name of the hold and a list of the mailboxes the hold applies to.

To connect to Security & Compliance Center PowerShell, see Connect to Security & Compliance Center PowerShell.

In-Place Holds

Run the following command in Exchange Online PowerShell to identify the In-Place Hold that's applied to the mailbox. Use the GUID for the In-Place Hold that you identified in Step 1. The command displays the name of the hold and a list of the mailboxes the hold applies to.

If the GUID for the In-Place Hold starts with the cld prefix, be sure to include the prefix when running the previous command.

Important

As we continue to invest in different ways to preserve mailbox content, we're announcing the retirement of In-Place Holds in the Exchange admin center (EAC). Starting July 1, 2020 you won't be able to create new In-Place Holds in Exchange Online. But you'll still be able to manage In-Place Holds in the EAC or by using the Set-MailboxSearch cmdlet in Exchange Online PowerShell. However, starting October 1, 2020, you won't be able to manage In-Place Holds. You'll only be remove them in the EAC or by using the Remove-MailboxSearch cmdlet. For more information about the retirement of In-Place Holds, see Retirement of legacy eDiscovery tools.

Microsoft 365 retention policies

Run the following command in Security & Compliance Center PowerShell to identity the Microsoft 365 retention policy (organization-wide or specific location) that's applied to the mailbox. Use the GUID (not including the mbx, skp, or grp prefix or the action suffix) that you identified in Step 1.

Identifying mailboxes on hold because a retention label has been applied to a folder or item

Whenever a user applies a retention label that's configured to retain content or retain and then delete content to any folder or item in their mailbox, the ComplianceTagHoldApplied mailbox property is set to True. When this happens, the mailbox is considered to be on hold, as if it was placed on Litigation Hold or assigned to a Microsoft 365 retention policy. When the ComplianceTagHoldApplied property is set to True, the following things may occur:

  • If the mailbox or the user's user account is deleted, the mailbox becomes an inactive mailbox.
  • You aren't able to disable the mailbox (either the primary mailbox or the archive mailbox, if it's enabled).
  • Items in the mailbox may be retained longer than expected. This is because the mailbox is on hold and therefore no items are permanently deleted (purged).

To view the value of the ComplianceTagHoldApplied property, run the following command in Exchange Online PowerShell:

For more information about retention labels, see Overview of Microsoft 365 retention labels.

Managing mailboxes on delay hold

After any type of hold is removed from a mailbox, a delay hold is applied. This means that the actual removal of the hold is delayed for 30 days to prevent data from being permanently deleted (purged) from the mailbox. This gives admins an opportunity to search for or recover mailbox items that will be purged after a hold is removed. A delay hold is placed on a mailbox the next time the Managed Folder Assistant processes the mailbox and detects that a hold was removed. Specifically, a delay hold is applied to a mailbox when the Managed Folder Assistant sets one of the following mailbox properties to True:

  • DelayHoldApplied: This property applies to email-related content (generated by people using Outlook and Outlook on the web) that's stored in a user's mailbox.

  • DelayReleaseHoldApplied: This property applies to cloud-based content (generated by non-Outlook apps such as Microsoft Teams, Microsoft Forms, and Microsoft Yammer) that's stored in a user's mailbox. Cloud data generated by a Microsoft app is typically stored in a hidden folder in a user's mailbox.

When a delay hold is placed on the mailbox (when either of the previous properties is set to True), the mailbox is still considered to be on hold for an unlimited hold duration, as if the mailbox was on Litigation Hold. After 30 days, the delay hold expires, and Microsoft 365 will automatically attempt to remove the delay hold (by setting the DelayHoldApplied or DelayReleaseHoldApplied property to False) so that the hold is removed. After either of these properties are set to False, the corresponding items that are marked for removal are purged the next time the mailbox is processed by the Managed Folder Assistant.

To view the values for the DelayHoldApplied and DelayReleaseHoldApplied properties for a mailbox, run the following command in Exchange Online PowerShell.

To remove the delay hold before it expires, you can run one (or both) the following commands in Exchange Online PowerShell, depending on which property you want to change:

Or

You must be assigned the Legal Hold role in Exchange Online to use the RemoveDelayHoldApplied or RemoveDelayReleaseHoldApplied parameters.

To remove the delay hold on an inactive mailbox, run one of the following commands in Exchange Online PowerShell:

Or

Tip

Fortisiem Duration That Logs Are Hold

The best way to specify an inactive mailbox in the previous command is to use its Distinguished Name or Exchange GUID value. Using one of these values helps prevent accidentally specifying the wrong mailbox.

For more information about using these parameters for managing delay holds, see Set-Mailbox.

Keep the following things in mind when managing a mailbox on delay hold:

  • If either the DelayHoldApplied or DelayReleaseHoldApplied property is set to True and a mailbox (or the corresponding user account) is deleted, the mailbox becomes an inactive mailbox. That's because a mailbox is considered to be on hold if either property is set to True, and deleting a mailbox on hold results in an inactive mailbox. To delete a mailbox and not make it an inactive mailbox, you have to set both properties to False.

  • As previous stated, a mailbox is considered to be on hold for an unlimited hold duration if either the DelayHoldApplied or DelayReleaseHoldApplied property is set to True. However, that doesn't mean that all content in the mailbox is preserved. It depends on the value that's set to each property. For example, let's say both properties are set to True because holds are removed from the mailbox. Then you remove only the delay hold that's applied to non-Outlook cloud data (by using the RemoveDelayReleaseHoldApplied parameter). The next time the Managed Folder Assistant processes the mailbox, the non-Outlook items marked for removal are purged. Any Outlook items marked for removal won't be purged because the DelayHoldApplied property is still set to True. The opposite would also be true: if DelayHoldApplied is set to False and DelayReleaseHoldApplied is set to True, then only Outlook items marked for removal would be purged.

Next steps

After you identify the holds that are applied to a mailbox, you can perform tasks such as changing the duration of the hold, temporarily or permanently removing the hold, or excluding an inactive mailbox from a Microsoft 365 retention policy. For more information about performing tasks related to holds, see the one of the following topics:

  • Run the Set-RetentionCompliancePolicy -AddExchangeLocationException <user mailbox> command in Security & Compliance Center PowerShell to exclude a mailbox from an organization-wide Microsoft 365 retention policy. This command can only be used for retention policies where the value for the ExchangeLocation property equals All.

  • Run the Set-Mailbox -ExcludeFromOrgHolds <hold GUID without prefix or suffix> command in Exchange Online PowerShell to exclude an inactive mailbox from an organization-wide Microsoft 365 retention policy.
