Manual Undo Suspend Office 365 user accounts

Summary: If you performed Suspend operation under Office 365 or hybrid account and want to return it back, Cayosoft Administrator doesn't have the Undo Suspend operation for Office 365 users, so you need to re-assign licenses and convert mailbox from Shared to regular manually.

Manual Undo Suspend Office 365 user accounts

Cayosoft Administrator calls Disable-RemoteMailbox as part of  the Suspend | Office 365 User rule execution, if the Convert to Shared Mailbox setting is set to "No". So, to undo suspend the Office 365 user account, you need to perform different steps depending on your Suspend | Office 365 User rule settings.

Follow the steps below to revert license and mailbox changes for Office 365 users:

1. In the Web Portal, select suspended account and run Undo Suspend command. This will rollback all changes made in on-premise AD.
2. If you converted user mailbox to shared mailbox during Suspend, you need to convert if back to regular mailbox:
   
   1. Run the Microrosft 365 Admin Console, under Admin Centers selects Exchange.
   2. In the Exchange Online Admin Center, go to Recipients section and select Shared from the top navigation bar.

   3. In the right pane select Convert to Regular Mailbox command.

      

   4. Select the user account in the Web Portal, assign license using the Office 365 License command, and set back required mailbox settings (like POP) using the Mailbox command.
3. If your Suspend | Office 365 User rule configured to remove Office 365 license and Convert to Shared Mailbox is set to 'No' you need to enable remote mailbox for the user:
   1. Login to the Web Portal.
   2. Find the user and run the Enable Mailbox action.
   3. Select Mailbox Type: Remote, choose license, update other properties if you need so and finish wizard.

   Undo Suspend user accounts that had remote mailboxes with in-place archive

   After suspend a user that had remote mailbox with in-place archive enabled you can get this error in the Microsoft 365 Admin Console when selecting the user:

   This is expected behavior if you have option Remove license, mailbox and archive mailbox set to Yes in the Suspend | Office 365 User rule.

   To get rid of this error you need:

   1. Enable remote mailbox for the user, you can do this by the Enable Mailbox action in the Web Portal as it described in step 3 in the previous section.
   2. On the Exchange Server, run the Exchange Management Shell.

   3. In the Exchange Management Shell, run the following command:

      Set-RemoteMailbox -Identity <user@domain.com> -ArchiveGuid <archiveGUID>

      where:

      • <user@domain.com> is userPrincipalName of the problem user.
      • <archiveGUID> is the cloud archive guid from the error message (for the error above it will be 05096fc9-ddc6-4558-8a87-b4b742a61220)
        
   4. Check the user properties in the Microsoft 365 Admin Console.
