Unable to disable archiving for a user after moving to o365

[DM21]

We recently moved a user to o365/EOL (EV worked fine).  We had to move them back (for some testing) and now the EV won't let us disable archiving for the the user.  "An error occurred trying to disable the mailbox.  The mailbox has not been disabled".   Any ideas on why this no longer works?

We are on EV  v12.3.

Hi,

There might be several reasons why this does not work. Is there still an archiving task for the mailbox server? Can you sync that mailbox? If you run provisioning, do you see that mailbox in the reports? Disabling archiving can be done using SQL.

 UPDATE Archive SET ArchivingState = 2 WHERE ArchivingState = 1 AND ArchiveName = 'Smith, John'

If you have multiple Smith, John, rename the arhive for that user to something unique, like Smith, John (left)
