Outlook 2007 slow to open

I recently installed Outlook 2007 on a HyperV Windows 2008 R2 server terminal server talking to Exchange 2010 on another HyperV on the same box.

The server is a Dual Xeon with RAID 10 SAS drives pumping out 800Mb/s throughput yet Outlook 2007 would take about 8 seconds to open. Rubbish!

I found by disabling all add-ins in Outlook 2007 the open time was 75% faster – down to 2 seconds. More like it!

To disable the comms add ons do the following:

  • Navigate to C:\Program Files (x86)\Microsoft Office\Office12
  • Find Outlook.exe and then right-click it
  • Select Run as administrator
  • In Outlook go to Tools > Trust Center
  • Select Add-ins on the left side of the window,
  • click on the Go button on the bottom.
  • Uncheck all add-ins except windows
  • OK all the way out
  • Restart outlook and notice the difference!
