I have a user who has 'full' permissions as a resource in Project Server 2010. For three months he was able to edit projects in PWA as well as MS Project. For some reason, he can now only edit (i.e. save) projects in PWA but when he opens them in MS Project it says "you selected a project that can be only opened read only".
In other words, he can check out and edit projects in PWA but not in MS Project.
No permissions were changed on his user. He has cleared the local cache but this didn't help.
Any ideas?
