Long story short.. restored a backed up data base. Followed all the steps to create a recovery database, successfully mounted a clean recovery db. get-mailboxstatistics - database recover displayed the user "Waters, Cliff"
restore-mailbox -identity "Waters, Cliff" -recoverydatabase recovery -recoverymailbox cwaters -targetfolder recovery
The specified user "Waters, Cliff" couldn't be found.
Umm what? Statistics shows the mailbox is there, what am I doing wrong?
Of note: new-mailboxrestorerequest fails at 18%, IDK where to look to determine the reason. But the data I'm looking for is subfolders within teh users Deleted Items folder. I was able to restore the DeletedItems via
new-mailboxrestorerequest -sourcedatabase recovery -sourcestoremailbox 'Waters, Cliff' -targetmailbox cwaters1 -allowlegacydnmismatch -targetrootfolder restore -includefolders 'DeletedItems'
But it was empty... it had teh deleted 2014, deleted 2015 folders that he created inside his Deleted Items however they were all empty.
