We're migrating users from Exchange 2007 to 2013. We've noticed a few users, specifically those who shared out their contacts, now have duplicate Contacts - user@email.com folder groups.
For example, say I'm migrated to the new exchange environment. I will now have two Contacts - user@email.com folders. The newly created and default folder is empty. The old contacts remain in the other folder but users don't see them when using ActiveSync since it only syncs the default user group.
Any way to avoid this or having the user copy/paste all of their contacts to the default list?
