Outlook 2007: Friend And Foe

I upgraded from Outlook 2003 to Outlook 2007 three or four months ago. For the most part, I love it. But I’m not smitten. Far from it. Here are my likes and dislikes:


  • The overall interface is vastly improved
  • The To-Do Bar is awesome. I use it every day to keep myself on track and on task, quite literally.
  • The enhanced categorization tools are also very useful


  • S.L.O.W.
  • Prone to weird behavior at times. Example: Sometimes when I get new mail, it shows the number of new messages next to the folder Inbox (2), but the messages aren’t actually displayed at the top of the inbox. Clicking on another folder, then coming back to the inbox will show those new messages. It hasn’t happened in a while, so maybe it’s resolved itself.
  • Did I mention S.L.O.W.

I know there are a lot of Outlook-haters out there, and for good reason. It’s a very bloated piece of software that can be a lot to deal with. But I have so much information tied up in it, that it’s hard for me to picture moving to another tool. Not to mention that I synch my calendar and contacts to my BlackBerry. So until I find something that can do e-mail/calendar/contacts better (and take in all my legacy data), I’m going to stick with it.

    I have actually found Outlook 2007 to be as fast as Outlook 2003. Could it be an issue with other software which affects your network connection, such as a firewall, old antispam software or other old Outlook plugins? If so, updating the other software might solve the problem with Outlook 2007 being slow on your computer.

    when I upgraded to Outlook 2007 12 months ago I had similar problems, you’d have thought MS would have fixed them by now, however, I found and implemented the following – successfully

    Regarding outlook 2007 slow, hangs after upgrade:
    We have the fix for you.
    Part of the issue comes from upgrading from Outlook 2003 or earlier because Outlook 2007 uses your account settings to create new ones for you. When you upgrade to 2007 you will need to locate four .DAT files and rename them…
    STEP 1: Turn off Outlook 2007 and Locate these files
    For some reason, during the upgrade these four files can become corrupted – the migration from 2003 to 2007 isn’t the smoothest but not having to create all your POP3 accounts again is excellent.
    1. extend.dat – you will find this file in the location | Drive Lettter:Documents and Settingsuser-directoryLocal SettingsApplication DataMicrosoftOutlookextend.dat //change it to extend.old
    2. views.dat – may not find it most of the time

    3. frmcache.dat – Drive Letter:Documents and Settingsuser-directoryLocal SettingsApplication DataMicrosoftFORMSFRMCACHE.DAT //change it to FRMCACHE.old
    4. outcmd.dat – C:Documents and Settingsuser-directoryApplication DataMicrosoftOutlookoutcmd.dat //change it to OUTCMD.old
    STEP 2: Restart Outlook 2007
    1. Send yourself some test emails and watch the messages appear.
    We contacted Microsoft Office 2007 support and workshopped this fix with them. They did not hear of this problem until we made first contact. Together, with the help of their support team (merv m. specifically), we found this simple solution above in a matter of 40 minutes. I was very impressed with their willingness to work through a fix together.
    As of today, they do not have plans to create a patch for this small bug but they are gathering bug fixes for a future service pack down the road. Right now (MS said) their focus is building a service pack for VISTA’s bugs.

    Yeah, I know Thunderbird has got a cult following, and probably for good reason. But my understanding is that it’s e-mail only, and doesn’t also do Contacts and Calendar like Outlook. I rely on those features of Outlook tremendously.
