Hi CTOCsna,

If it's the mail merge main document you mean, one way we found to
work around the problem of the file acquiring an exclusive lock was to
set its read-only attribute (via right-click/Properties/Read-only). In
our case we were using document templates (.dot) as the basis for the
merge so we've never tried it using .docs.

Another way around it was to copy the file locally and use the local
copy for the merge. (The users didn't have to copy the file manually
as our s/w was automating Word to perform the merge.)

Cheers.

Ed
