Microsoft has published a Preliminary Post Incident Report on last week s events which broke Outlook on Windows for millions of users, making emails impossible to view or create.
It was on the evening of May 11th, UK time, and in the middle of the working day in North America (18:24 UTC, 19:24 BST, 11:24 Pacific), that many Office 365 customers using Outlook on Windows observed a frustrating problem: blank emails (or maybe showing just one line), even though a few lines of the email could be previewed in the list of messages. Attempts to create or reply to an email allowed a line of text to be typed, but when the user pressed enter, the text disappeared.
