Currently, all mail is flowing through Exchange 2010, OWA is correctly redirecting and ActiveSync is working. The issue I am having is when a user tries connecting using Outlook Anywhere with autodiscover and their mailbox is still on the Exchange 2003 server. They are unable to connect to it. Mailboxes that have been moved the Exchange 2010 can be accessed over Outlook Anywhere via autodiscover. Help will be appreciated Thanks Moshe Mazor Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
