During Migration test runs from Exchange 2010 to Exchange 2013 we ran into a problem:
some users appear to have mailboxfolders in different languages like "Deleted Items" and "Verwijderde Items", but not all users an also not all folders for that user
If the "deleted Items" folder was the system folder in EX2010, then after migration that user, being migrated to the new server where the default mailbox setting regional nl-NL, his new DeletedItems system folder is : "Verwijderde Items" but it is empty.
Okay, this is no big deal, all the items can be found in the still existing "Deleted Items" folder, select all items and drag them to the Verwijderde items.... then delete the Deleted items folder (it is no longer a system folder so it CAN be deleted)
But it also happened to a user with his "Calendar" and "agenda": And now his agenda was empty, and on his iPhone after a very short time ALL his appointments were gone. (synchronization) Even more distressing for that user, it happened ALSO to his "Contacts" and "Contacten" : After synchronization he lost all his contacts ; you can imagine this users happy face ?
I Found the script Fix_Mailboxfolders.ps1 and ran it but since the regional setting on ex2010 was also nl-NL it did not work
My last resort was to export his restored old mailbos to a pst and disabled his mailbox, created a new one for him en imported the PST again... problem solved: but now his email UID has changed and ALL his appointments with other users get a "unknown user" message.
SO my question is:
How can I migrate a user who is known to have different foldernames (both dutch and US) and make sure the Dutch folder gets to be the system folder AND has all the items in it from de Us folder, AND the US folder gets deleted?
Anyone with a good powershell knowledge? There are about 100 users with duplicate Foldernames in the wrong language
I know the following arguments:
Mailbox userID, current System Foldername, New System Foldername,. I can run a script Before migration or After.
