A couple of weeks a go I started using a Groove workspace to centralize all the information/knowledge/documentation we have for Microsoft Exchange Server. Synchronization has been set up with a SharePoint library to make all those documents accessible to people not involved with the product on a daily basis.
Whenever I would add a file to one of the folders I always got a sync error complaining that the folder already existed. (Like I didn’t know…).
The only way out was to delete the entire folder both in Groove and SharePoint, sync, and then add the folder back on the SharePoint side. I tried a number of things but ended up asking a more SharePoint-knowledgeable colleague for help. He promptly resolved the issue and made a screencast about it.
