I have two computers that both have Office 2007 installed on them (an old machine, and a replacement).
How would I go about exporting the AutoCorrect entries on one machine and then importing them to another?
I haven't tried this (sorry), but I am pretty sure it will work.
Copy the appropriate
Found here (on Windows Vista): C:\Users\USERNAME\Application Data\Microsoft\Office\ or here (on Windows XP): C:\Documents and Settings\USERNAME\Application Data\Microsoft\Office\
The file you're looking for will have a name like MSO1234.acl. The 4 numbers refer to the language/locale code. Yours will most probably be either MSO2057.acl (for UK) or MSO1033.acl (for USA). Also, it's likely to be the one with the largest file size.
I recommend making sure all instances of Microsoft Office programs are closed before you make this change.
This will most likely replace the existing AutoCorrect entries saved on the second machine.
