Hello everyone!
We only have 3 mailboxes left in our Exchange Server 2019 on-premises, the rest was already migrated to Exchange Online (we have a hybrid environment). We cannot move the other mailboxes at the moment.
Since a couple of days however we receive the following warning message in the event log of our Exchange Server:
Event-ID: 9042 (MSExchange Assistants)
"Service MSExchangeMailboxAssistants. File Extraction Time Based Assistant for database <dbname> (<db id>) is exiting a work cycle. No mailboxes were successfully processed. 1 mailboxes were skipped due to errors. 0 mailboxes were skipped due to failure to open a store session. 0 mailboxes were retried. There are 0 mailboxes in this database remaining to be processed."
Unfortunately, that's all the error messages we receive and I have no clue how to find out which mailbox is skipped. Or why...
How can we find out which mailbox is causing the problem? How can we then solve it?
Many thanks!
Best regards,
Markus
