Hi!
Quick question, I have a mailbox, let say mailboxA, MailboxA have fullaccess to MailboxB, both resides in Exchange 2010.
Now is MailboxB migrated to Exchange 2013, will MailboxA be able to access MailboxB from his Outlook?
In my environment it is not the case and I just wonder if something is wrong or if it is by design. I can understand that new cannot access old environment but the other way around should work?
Any guidelines in which order I should migrate users? Start with Shared mailboxes and all users that have access to those mailboxes? I have no public folders.
Thanks!
