Validation errors for a mailbox archive GUID for Microsoft 365 users

Original KB number:   4053483

Symptoms

An administrator who signs in to Microsoft 365 admin center or Microsoft Entra ID may receive the following validation errors for some users:

"Failed to sync the ArchiveGuid <GUID> of mailboxMailboxGuid because one cloud archiveCloudArchiveGuid exists."

"Failed to enable the new cloud archiveCloudArchiveGuid of mailboxMailboxGuid because a different archiveArchiveGuid exists. To enable the new archive, first disable the archive on-premises. After the next Dirsync sync cycle, enable the archive on-premises again."

In this situation, updates to other property values of these users can't be synchronized from Microsoft Entra ID to Exchange Online.

Resolution

Update the msExchArchiveGUID (ArchiveGUID) property value in the on-premises organization to match the Exchange Online value. To do this, follow the steps for the scenario that corresponds to your on-premises configuration.

Scenario 1: You still have an Exchange server running in the on-premises organization

Here's how to keep the ArchiveGuid property value consistent between Exchange environments:

1. Run the following cmdlets from the Exchange Management Shell to retrieve information about ArchiveGuid and RecipientTypeDetails:

   Get-Recipient -Identity user@contoso.com | fl ArchiveGuid, RecipientTypeDetails
   

2. Run these cmdlets to update the value based on different situations, as follows:

   • Situation 1: The RecipientTypeDetails property is set to RemoteUserMailbox and the ArchiveGuid property is set to 0:

      Enable-RemoteMailbox user@contoso.com -Archive
     

      Set-RemoteMailbox -Identity user@contoso.com -ArchiveGuid <Cloud ArchiveGUID>
     

   • Situation 2: The RecipientTypeDetails property is set to RemoteUserMailbox and the ArchiveGuid property is already populated:

      Set-RemoteMailbox -Identity user@contoso.com -ArchiveGuid <Cloud ArchiveGUID>
     

   • Situation 3: The RecipientTypeDetails property value isn't RemoteUserMailbox (no remote mailbox is enabled for the affected user):

      Enable-RemoteMailbox user@contoso.com -RemoteRoutingAddress user@contoso.mail.onmicrosoft.com
     

      Enable-RemoteMailbox user@contoso.com -Archive
     

      Set-RemoteMailbox -Identity user@contoso.com -ArchiveGuid <Cloud ArchiveGUID>
     

Scenario 2: You no longer have any Exchange server running in on-premises, but you still have Exchange-related attributes in AD

In this scenario, you must install an Exchange server to manage the Exchange-related attributes for synchronized users.

To update the ArchiveGuid property value, run the following cmdlets from Active Directory PowerShell in a domain controller:

Import-Module ActiveDirectory

[guid]$guid = "Cloud ArchiveGUID"

Get-ADUser <user alias> | Set-ADUser -Replace @{msExchArchiveguid=$guid.tobytearray()}
