Single user with issues in his Newsfeed - Everyone. For all other users "Everyone" works fine. User is approx. 6 months old.
Message: SharePoint returned the following error: the operation failed because the server could not access the distributed cache. Internal type name: Microsoft.Office.Server.Microfeed.MicrofeedException. Internal error code 55. Contact your administrator for help in resolving this problem.
There seems to be nothing special about this user. As we use OneDrive for Business and he has a lot of shared content in his OneDrive I hesitate deleting his profile.
