Microsoft products are turning just buggy junk. On my corporate laptop running MS 365 my outlook hangs every damned time my VPN has a hiccup and I am forced to kill it in the Task Manager at least 4 times every day every time the message popup window “You cannot access this right now” appears. It is combination of bad Microsoft code and corporate IT mistakes but it still sucks.
Try rebuilding your wi-fi profile so VPN won’t hiccup. It takes a minute and might work.
