Outlook is dead! Long live Outlook!

I’ve been using Outlook 2007 (with my Exchange account) for about three months. Four times now, I’ve had all Office 2007 applications fail to start with the error “ProgramName is not a valid Win32 application”.

I was somehow able to fix it the past three times, but I can’t remember exactly what I did. I tried running the diagnostics, repairing and reinstalling Office 2007, and several other things. But I’m not sure what exactly fixed the problems. I’ve finally had enough so this time I completely uninstalled 2007 and went back to 2003. I really like some of the new features in Outlook 2007, but they aren’t worth the hassle…

However, I noticed that I started having problems in Outlook 2003 now; it looks like they are related to Contacts synchronization. After search the web, I tried to disable offline cache on my account and restarted Outlook, but it still failed. My email works, but I cannot search for contacts in exchange. So now I’m running scanost and scanpst on my files (found in C:Program FilesCommon FilesSystemMSMAPI1033 on my machine). It found errors in my PST and it’s still running the OST Integrity Check.

I hope this fixes the problems; I shouldn’t have to struggle to read my email.

Update: Nope! Still having problems…

Update 2: Fixed it! I had to shut down Outlook, rename the Outlook folder in AppDataLocalMicrosoft, delete and recreate the Profile in Control Panel -> Mail.

What a pain!

Update 3: I decided to switch back to Outlook 2003 at home as well, and I can’t believe how much faster it is on my home machine. It’s amazing…
