Mailbox has just been created and is not ready for backup. Please try again later

Good Day

Since some days there are Warnings like this in our Mailbox / Teams Backup

"Mailbox has just been created and is not ready for backup. Please try again later".
In the Logs:
21.01.2022 08:29:00 110 (2364) Error: Failed to get a mailbox session for <MAILBOX>
21.01.2022 08:29:00 110 (2364) Type: Veeam.Ews.Internal.ExServerCodeException

This happens also on Mailboxes from Users which are created several Months ago. It does not happen always on the same accounts.

Is there something known about this? Maybe a MS Problem (once again)?
VBO is Version 5.0.3.1035

Thanks

Hey @agrob,

This seems indeed like an issue on the MS side. Not sure if they changed something or there are temporary issues on their infrastructure. Nevertheless, if you could create a support call it could become handy. We might see others with the same issue

This error I have seen before, but that is not on users which are created several months ago. And just for your info, there is an additional cumulative patch: https://www.veeam.com/kb4270

Thanks for the Information Mike. I'll install the latest patch and wait over the weekend and check if the issue still exist. if yes, i open a case.

[agrob]

did install the latest vbo 365 patch. also the message is still present on several mailboxes.
no info about such a problem in the ms heath center in our tenant. so i opened a veeam case #02204495

Hi Andre,

I'll follow up on the case, but the ID doesn't seem to be valid.
Did you reopen the old case? Can't find it in the system.

[agrob]

Hi Polina

No i just opened the case today.... #02204495

[Polina]

That's your contract ID )
Anyway, I found the correct case ID: 05246698.
Thanks!

[agrob]

[agrob]
