Error “StalledDueToMailboxLock” when moving mailboxes to #Office365 in hybrid configuration
Found this link on twitter as I follow Exchange Server Pro @ExchServPro (great tips and articles always) who got it (via @mvanhorenbeeck) . I got this same error twice but when I did a move to O365 and used the ‘Suspend When Ready to Complete’ switch. Good information and suggestions in this article. Kudos and Thanks!!!
