Phones cannot connect with mailboxes homed on a remote Exchange 2003 server. RRS feed

  • Question

  • Lost our frontend server and setup new services on an existing Exchange 2003 server.

    The now current Frontend server is one of 3 Exchange 2003 servers.

    The Frontend server and one more Exchange server are on the same subnet and the 3<sup>rd</sup> is at a remote location.

    It is this remotely located Exchange server that users with phone cannot access their mailboxes homed on that server.

    This is what is working now.       

    1. All remoter Outlook clients can connect via rpc over http to all Exchange 2003 servers
    2. Phones can only connect to mailboxes homed on the Exchanged server located on the same subnet as the Frontend server.

    Can you offer any direction?

    As a business decision, we are gearing up to put new Exchange 2013 servers into a new forest and migrate the users.

    we are now looking at rehome affected users' mailboxes to the exchange server that is accepting the phone connections.

    Thank you,

    Stephen

  • Hi Stephen,

    In your case, I recommend you move the problematic mailboxes to the Exchange server that is accepting the phone connections for troubleshooting.

  • So you have 1 front-end and 1 back-end on same subnet and 2nd back-end is on different subnet.

    log on the front-end and try to access a mailbox hosted on the 2nd back-end with OWA, does it work?

    check if exchange version/patches are equal or higher on the front-end than on the 2nd back-end, that his a requierement.

    try to run an Exbpa from the front-end itself to see if more error are discovered.

    regards,
