It has now been 8/10 weeks since I installed the April/May OS update for Win 10 Pro, and despite many hours with MS support I'm still having issues with my Office 365 locally. It take several minutes for outlook to open, it show "trying to connect", "not responding", then asks for a password, after my password is entered it works. However it seems to loose connection and if I relpy to a message and send the email, a few times the email looks like it has been sent but on checking the sent folder it is not there, and is no longer in drafts, and has not been sent.
