HI,
I have a small 50 user exchange server 2013 that was upgraded from exchange 2003. I uninstalled 2003 to update the schema and this allowed me to install exchange 2013.
The issue i'm facing is, OWA works perfectly and mailflow is ok, but the outlook clients can't connect, auto-discovery works well because the establish connection and search for address are check off bu fails on the logon server with a GUIID {GuID@domain.com} as the server name and a mailbox with =SMTP:user@domain.com
I cant figure out what's wrong, I can't enter the server netbios or dns name, I still get server not available
