I have a task that is assigned to a user, but when he tries to open appears a error message saying "Sorry, this site hasnt been shared with you". I already confirmed and he have contribute permissions for the site. However, he can see on the page the tasks how are assigned to him, when he tries to open them is when the error message appears. What can I do so he could see the task that is assigned to him?
Note: Its on sharepoint 2013
Hmm... that's interesting.
I would first check the URLs to make absolutely sure that the Task is on a list that the user absolutely has access to.
Additionally I would then check the permissions of the Task itself (as in, the permissions of the Task List Item) to make sure that the user has access to it.
The only other problem I could think of is that if the Task has a Page Viewer Control on it that is pointing to a List / Form that the user doesn't have access to, that could cause some issue (but should really only affect the iFrame that the Page Viewer would try to populate).
