Make slow outlook 2007 run faster

Outlook 2007 has been running slow since I got it. I installed SP1 and keep it updated but it's still slow, especially when I Click Calendar or Contacts button in the navigation pane from Mail. That switch usually needs half to one minute to complete, which is too long for me.

I found that can be changed after I run outlook in safe mode: start -> Run dialog and type outlook /safe, in which I don't need to wait at all if I switch from Mail to Calendar or Contacts. And that was the case even after I ran outlook in normal mode later. The key is to run outlook in safe mode once then close it.

If the above trick stops working reliably, I would open the Outlook Add-ins manager by clicking the menu item Tools->Trust Center... Then click the second item on the left pane which is Add-ins. Then click the Go... button near the bottom on the right pane. The next step is to Disable all COM Add-ins, especially the Business Contact Manager for Outlook. The last step is to restart outlook and it works again.

Updates: Install the Office 2007 Service Pack 2 and I believe MS finally found the cure for the slow outlook. With the Office 2007 SP2, it now takes me less than a second to switch among Mail, Contacts and Calendar.

Another command that may be useful is outlook /cleanrules
This command can remove corrupt mail rules and alerts.

Kudos as well... worked fine. One thing I thought I would note in the event it's useful.

I found that just the act of disabling the add-ins, exiting Outlook, and then starting it again, **and then turning the add-ins back on (the ones I wanted)** the fix STILL worked.

Maybe the add-ins needed to be somehow "reset". In any case, the good news is that you can still use the add-ins you want.

Amazing tip. So simple yet to useful to see outlook behave much faster (my PST files are over 2 GB each).

Some time ago my friend told me a next story. He said that he had had a problem with outlook emails. And he hadn't settled theirs. I couldn't relieve him and was disappointed. Luckily for us this morning I have found out - exchange ost recovery on the Inet. The software resolved my friend's problems ultimately easy.
