Veeam Backup for Microsoft 365 • Mailbox is already processed by another job

Case #07625243

Since Sunday we have started to see this error:
As far as I can tell nothing else should be backing up this data.

We are running Veeam 365 7.1.0.2031 as we cannot install version 8 as the server is Server 2012 R2 (this backup server is also a secondary domain controller so we cannot do an inplace upgrade of it until we have finished building another secondary domain controller).
