Very strange... I have one O365 user that her outlook shows disconnected a couple times a day. When this happens, she still has internet but she can't hit "outlook.office365.com" her lync is still connected, and I can remote in. I can hit login.microsoftonline.com just fine, but outlook wont connect, and outlook.office365.com isnt accessible either. After 10 min or so it will start working again.
This happens in the office, or from home. There are no proxy settings anywhere, already ran malware and AV scans. Anyone seen anything like this ?
