Microsoft’s Outlook email app for Windows started crashing at launch for a large number of users around the world today. Office 365 business users reported that Outlook launched and then crashed immediately, seemingly after a recent update. “We’re investigating whether a recently deployed update could be the source of this issue,” explained Microsoft initially in a Twitter status update.

“Our teams have begun to roll out a mitigation for an issue affecting user access to Outlook,” says Microsoft in a statement to The Verge.

Microsoft now says it’s rolling out a fix for the issue that should reach all customers over the next few hours. Affected users should be able to log into Outlook on the web until the issues are fully resolved. IT admins over on Reddit also tested a variety of workarounds to roll back the update that appears to have caused the crashes today.

Update July 15th, 3:36PM ET: Added tweet from Microsoft about a fix.
