hi, !

could you comment what the (exact) occassions are when this happens ?
AFAIK ...\AppData\... is a system reserved (and hidden) location
where you DO NOT need/have/want/... to put data in there (a few and specific situations excluded)

perhaps the users are opening (individual) files directly from an e-mail message ?
(instead or saving first the whole set of files in a specific location on his HD ?)

hth,
hector.

__ OP __
We are using external links to files residing in the same folder as the file requesting the link.
Occassionally, these links decide to look in \Users\username\AppData\Roaming\Microsoft\Excel\
instead of the same folder where the file is for updates.
And there are no files with the same names in that location, so the information doesn't update.
This can cost $thousands$ if the user doesn't realize the links aren't working.

How can we stop this from happening?
I used to be able to open files from the same folder using office, file open, and it worked.
It seemed to be more of a problem when opening files using Windows explorer to open files.
But now the problems have returned even when the links were done using Office, file, open...
