I installed Office 2010 32 bit on my Windows 7 64 bit computer because I didn't realize that the install program defaults to 32 bit even though the OS was 64 bit. After a couple of months, I discovered that bit of information. So now I want to reinstall Office 2010 as the 64 bit version but must first uninstall the 32 bit version. For most Office programs this is a no brainer since all the data files are independent of the installation and I have made no customizations. Not so for Outlook though. I do not want to loose my account settings, nicknames, custom views and quicksets, rules, etc.. I know that the data files (pst) are in My Documents. Where do I find all of the rest of the "set up" files for Outlook 2010? Can I just back those up and reinstall them after uninstalling and reinstalling Office 2010?

You won't lose anything when you uninstall 32-bit. Outlook will pick up the old profile and settings. (Rules and autocomplete cache are stored in the mailbox or pst.)

Note that if you use addins or sync with a smartphone, you'll want to keep the 32bit version as many addins won't work with 64bit outlook.

Thanks, loads. I took your word for it and did the 32 bit uninstall and 64 bit install. Everything was carried over including Quick steps, nicknames, and view setting.

I don"t think is a matter of losing anything or not. the question we need to ask is why Microsoft doesn"t support their own products? i still can't believe we need to uninstall office 2010 64 bit to be able to sync with my windows mobile 6.5. This is really ridiculous, Microsoft should fix this issue and not asking people to downgrade from 64 bit to 32 bit.
