Exchange 2013 SP1 There are 3-4 users getting dual archive mailbox

Issue :

1. Users are in Outlook 2013/Outlook 2010 and OWA, few users are getting dual Archive mailbox

2. For the same user, Inbox is visible in Archive Mailbox, both from Outlook and OWA

Resolution :

1. Test-E-mail Autoconfiguration" from Outlook shows that the Outlook is connecting to another users Mailbox and Full mailbox permission is added for another user's Mailbox in the user mailbox


Removing full Mailbox permission for another user mailbox from the original user's Mailbox resolves the issue


2. When Archive Mailbox is enabled for user, Exchange will copy the frame like inbox, sent and delete Item etc but will not publish until data is moved to Archive mailbox via Retention Policy
