Case # 02625296
Is there a limit on what VBO365 can pull down? Running into an issue where i get an error for certain mailboxes.
"Failed to synchronize item changes. The server cannot service this request right now. try again later"
Hopefully the below could work >?
Found this online,
"Backup of one single mailbox was constantly failing.
What appeared was mailbox was over 100GB in size When running Get-MailboxStatistics against it – do not know how it is possible though as O365 gives you 100GB for the mailbox.
After enabling archive for this mailbox and runnig Start-ManagedFolderAssistant so the main mailbox went down below 100GB – the backup went just fine"
