We have just upgraded to Exchange 2013 from 2010 and now find that, for users who have links to multiple mailboxes in outlook, that also have online archives, the archives are shown as "Online Archive - joe.blogs@example.co.uk" for all of the archive mailboxes despite the fact that one may be Joe Blogs, but the others may be John Smith or Davey Jones.
Is this just a "new feature" or can it be fixed?
