If one of the following errors occurs when you are attempting to restore
Microsoft Exchange Online data in a Cloud (Microsoft Office 365) backup set:
"The server cannot service this request right now. Try again later."
"The mailbox database is temporarily unavailable. Cannot open mailbox."
Do the following:
1. Attempt the restore activity at a later time.
2. If the error still occurs, increase the value of the "Miscellaneous"
advanced parameter "Office365RequestRetry" and reattempt the restore activity.
3. If the error still occurs, increase the value of the "Miscellaneous"
advanced parameter "Office365RequestRetry" and reattempt the restore activity
at a later time.
IMPORTANT: The duration of restore activities will be exponentially lengthened
for each Microsoft Exchange item with each additional retry allowed by the
advanced parameter "Office365RequestRetry".
