I was given links to a B&R 9.5 update, plus an update to O365, and that has fixed the problem.

Last nights backup of mailboxes went without a hitch.

For the sake of others, I had some minor issues with the service not starting when I upgraded.

I use a non-domain repository, which entails changing the service's logon account. During the install, the logon credentials were swapped back to the default 'Local System' account. After I changed them back to my custom account, everything worked fine.

I got hold of the hotfix before it was public, and the backups worked fine. However, we do get an error for unlicenced users. From what I understand, Update 1 for Veeam Backup for Office 365 is only going to give a warning.

Are there any differences between the pre-release-hotfix and the public Update 1? I can't install it since the build number is the same (912), so I would presume the hotfix and public update is identical?

jonsibar,

Kindly, check with the support team. Most likely the fix you are referring to was included in the update.

Update: Seems like the retry of the job was the one that failed. The 'main' job reported only with a warning.

Judging by the build number, you have the update that went public already installed.

Any chance you previously tried to process all mailboxes, while now adding mailboxes explicitly? Behavior is a bit different in these cases, due to some internal logic (in the first case the job will give an error for each unlicensed mailbox and finally fail after retry). As a workaround, you can try to assign and revoke licenses from these mailboxes in Office 365 admin center, this should ensure Veeam Backup for Office 365 doesn't touch them.

Actually, it's the other way around. We initially started out backing up a few mailboxes, and increased the number gradually to see how long the backup would take. In the end we switched to 'all mailboxes'

Ah, ok, this explains the difference in behavior, not the fact you have some different version of the update code.

I have the same issue. Set to all mailboxes and first job shows a warning status but shows 42 failures in the job, then 3 retries all have status failed.

Just to avoid further confusion, the unlicensed mailbox issue is a different one, the original 'Object reference not set to an instance of an object' issue started to occur on January, 1st and discussed in this thread is fixed by the Update 1. The behavior you're describing is expected for such mailboxes (not licensed in Office 365).

Thanks for the clarification foggy. I'll put in a feature request.
