I have problem with one user, because when he saves item in SharePoint 2013 library, he has to wait ~2 minutes to finish saving.
I tried changing his computer on completely new and it still happens. When I log on my profile on his computer everything is OK. So problem is (in my opinion) on his account in SharePoint (or permissions?).
In my company I have ~100 users and just this one has the problem. His permissions are standard (Edit). I don’t know what I have to do to fix this issue? What to check?
