Security News > 2020 > July > Is it Patch Blues-day for Outlook? Microsoft's email client breaks worldwide, leaves everyone stumped
Microsoft's desktop email client Outlook has stopped working worldwide for countless users, whether they are using it with an on-premises Exchange server or with the Office 365 cloud.
As a workaround, users can utilize Outlook on the web or their mobile clients.
It noted on its Outlook.com status page: "We've confirmed that the issue has been successfully resolved after extended monitoring of our telemetry. If users are continuing to see impact, please restart your Outlook client for the changes to take effect."
A spokesperson for Microsoft also told us: "Our teams have begun to roll out a mitigation for an issue affecting user access to Outlook." The spokesperson added that Wednesday's breakage was not a result of the July Windows Update batch as previously speculated.
Undoing the Patch Tuesday security patches may have had no effect, so if you've uninstalled them, you should probably reapply them because they fix up a remote-code-execution hole in Outlook.
