Fixing an agonizingly slow Exchange / Outlook 2007 connection

Have been banging my head against various surfaces trying to figure out why a new account with Intermedia.net is so slow with Outlook 2007.

Microsoft Exchange Proxy Settings

Intermedia of course wanted to blame Comcast, which showed some minor packet loss ’round about their interface to Level 3 in NYC. Comcast in turn scoffed at this and suggested placing the blame on Exchange.

Finally got a suggestion from Intermedia support to check RPC over HTTP. Sure enough the “On fast networks, connect using HTTP first, then connect using TCP/IP” was off. Switched on, used KnockOut to force a quick restart of Outlook.. and suddenly no more ten minute logon process! Now let’s see if the random freezing also goes away.

My bad for not double checking what autodiscover was doing over there in the corner during the install process.
