Cause
Incorrect size of mailbox is set on Exchange server.
Resolution

Open Exchange Management Shell and check quotas of the problem mailbox using the command:
[PS] C:\Windows\system32>Get-Mailbox -Identity "Mailbox Owner" | fl ProhibitSendQuota, ProhibitSendReceiveQuota, IssueWarningQuota
I the values that you see do not correspond to values specified in POA, then update them using the command:
[PS] C:\Windows\system32>Set-Mailbox -Identity "Mailbox Owner" -ProhibitSendQuota <value> -ProhibitSendReceiveQuota <value> -IssueWarningQuota <value>
- Resubmit the failed task.
