I had the most painful experience with Outlook 2010 32 bit on Windows 7 64 bit. Don’t ask me why I installed the 32bit version on the 64 bit OS….the 32 bit CD was just handy on that day.

After opening Outlook for couple of minutes, it would stop responding and I had to kill it using the Task Manager. I applied all latest patches, disabled add-ons and tried several other solutions, including deleting and recreating profiles, but none of the solutions helped. I finally moved over to Thunderbird and it worked great for quite some time. And then I got couple of email attachments, which for some reason got corrupted, when I tried to save them from Thunderbird. This got me worried because I had to ask my client to send me attachments several times, in different formats (PPTX, PPT etc). However, I realized that if opened that email using Outlook (I use IMAP), it had no problem opening the attachments. To make the story short, I realized I had to get back to Outlook. I had no other option.

I then uninstalled the MS Office 32 bit version and installed the 64 bit version and now, everything is working perfect.
