I am having an odd issue, some users are constantly receiving a request to enter there credentials for Outlook and Skype. We have a hybrid O365 environment and for the life of me I can not figure out why this keeps happening. The fix I have found is to remove all saved credentials and then have them re-enter but for some users this happens every few weeks and it is extremely frustrating. Anyone else see this of know how to fix it? O365 support hasn't been much help.
