Hi,
For several months I did my migrationfrom Exchange 2010 to 2013 (CU4)
Currently I work with Exchange Server 2013 and 2007 (in coexistence mode).
Since migrating my Exchange 2010 to 2013, customers who still have mailboxes on Exchange 2007 encounters problems in Outlook anywhere that become non-functional (prior to Exchange 2010 migration to the 2013 Outlook Anywhere works correctly for mailboxes located
on Exchange 2007), and another more serious problem is that some users on my Exchange 2007 when he opened their mailboxes through OWA are randomly in switched to other accounts so that access to other messages which is a very serious breach of security for
our customers !!!!!!!!!!!
Do you have an idea about these two issues please ? !!!!
