Speed up Outlook 2007 Access

Wednesday, November 11, 2009
I've heard several clients complain that Outlook 2007 takes too long to start up compared to previous versions of Outlook. In most cases I've found that this is because Outlook 2007 is configured to connect to Exchange using Outlook Anywhere, even on their corporate LAN/WAN.

Here's how to correct this:
  • Open Outlook and click Tools > Account Settings, or in Control Panel open Mail and click E-mail Accounts.
  • Double-click the Email account name that's using Exchange to edit its properties
  • Click the More Settings button
  • Click the Connection tab
  • Clear the Outlook Anywhere checkbox that reads, Connect to Microsoft Exchange using HTTP
  • Click OK > Next > Finish
  • Restart Outlook
