I ran a cutover migration batch. All mailboxes, groups, contacts, etc. were migrated successfully.
We are running Exchange 2010 (SP3) and have about 30 users with Personal Archive mailboxes.
I cannot find any support for the migration of 2010 Personal Archive mailboxes to Office 365 Inline Archive mailboxes through the cutover migration. I read one post that mentioned exporting each user's archive to individual PSTs, then importing them into each user's archive mailboxes. I'm hoping there's a more automated way.
If any experts out there have actual hands-on experience with this issue, or know a reliable source for a better solution, I would greatly appreciate your help.
