Upgrading from Office 2010 x32 to x64

4161 Views 1 Reply 2 Participants Last post by  pip22
I installed the x32 version of Office 2010 on my 64-bit system unwittingly and now realize I need to install the 64-bit version. Is it possible to do an "upgrade" from x32 to x64 in a way that won't erase my Outlook configuration?

I have a lot of accounts configured in Outlook and it will be a PITA to get them all back in and configured correctly with a totally new installation, so any help avoiding that is appreciated.

In existing Outlook, use the File >> "Import & Export" tool to create a PST file -- this will contain all folders, messages & contacts.

Then go to "Tools >> Accounts" & export each account as an "IAF" file

Now remove Outlook 32-bit.

When you've finished installing Outlook 64-bit, use File >> Import & Export to import the PST file.

Then go to Tools >> Accounts & import each IAF account file.
