Does Teresa have the ability to make changes in the shared drive directly? For instance, if Jive was removed from this scenario would she be able to change it directly? This could be a permission-related, but generally speaking, if they can access the shared drive file and has edit access to it, she should be able to using jive for office.
Yes, Teresa has access to the shared drive.
Is it possible that there is a conflict due to two people having the same file open on the shared drive and trying to edit at the same time? Thus, it would be a Microsoft permission issue rather than a Jive one?
