I try to restore an O365 mailbox to a pst file.

I lots of the errors below in the log and it is not restoring.

We are running 11.28.115

Any idea what the problem can be? At this time i am running a verification job on the storage.

Hello @Riconl 

Thanks for the great question, I am assuming this is the doco you are following:

Can you confirm if you are able to restore out of place or in-place back into O365? This will validate that the data you are restoring is healthy and its just the .PST operation that is failing. 

Kind regards
