|My school uses Office365 email. Recently, whenever I open the website, the tab or window closes itself within about a minute. Every time I reopen it, the same thing happens. I'm not sure if this is entirely 'crashing', since when I open it from Recent Tabs or navigate back to the website, I'm still logged in. Also, interestingly, if I'm composing a message, instead of the tab/window closing I'll simply get a message asking if I really want to close since this will result in loss of unsaved work. Saying 'stay on this page' keeps me on the page as it normally would... until the message pops up again about a minute later.|
I've run Malwarebytes and deleted what it found, but the problem persists.
