Good Day,
Have migrated all settings from ISA 2004 server to TMG 2010 (including certificates) and it was good.
* Mail flow: went through TMG successfully after changing the Exchange 2010 server's gateway to the TMG. (Client Access Server role & Hub Transport server role are on the same server)
* OWA clients : they can connect successfully to their mailboxes through both http://mail.company.com/owa&https://mail.company.com/owa
*Outlook Anywhere clients: I didn't test them yet & don't know if they will connect successfully or not
Active sync clients were unable to logon to their mailboxes . password prompts keep appearing.
on the TMG Server log & Report : "12309 the server requires authorization to fulfill the request.access to the web server is denied."
any suggests to solve this issue
Regards
Elias Dayeh
