Hi All,
I have an existing running Exchange 2007 SP3 RU13 server acting as MB,CAS,Transport using a Barracuda SPAM for SMTP (MX Record is assigned to here), and a TMG2010 server performing all ActiveSync, Outlook Anywhere, and OWA connectivity.
I have built a new Exchange 2013 SP1 server that will (for the meantime) act as a MB & CAS server only.
I successfully migrated a testuser mailbox to the new EX2013 server from the EX2007 server. The problem is that once migrated, OWA and Outlook can't access the mailbox.
OWA form our URL gives the message: Outlook Web Access is currently unavailable. If the problem continues, contact technical support for your organization and tell them the following: No Client Access servers of the appropriate version can be accessed from the Internet
If I run OWA from the EX2013 URL it works ok, but not for MBs on the EX2007 server.
I tested this configuration in a VM lab and it worked ok. All I had to do was move the mailbox, then run Outlook. Outlook automatically found the new server and opened the MB.
Basically what I need to do is move all our existing MBs from the old 2007 server to the new 2013 server. I want to continue to use the exisiting transport/CAS/EDGE services on 2007 without having to rebuild both the internal and external comunications infrastructure at the present time.
How can I get the EX2013 server to act as the MB server for the EX2007 communications infrastructure?
