At last there’s a fix. Millions of Outlook users been plagued with failed restarts and missing emails since Microsoft released its mandatory January security updates. Now the company has confirmed a new emergency update to put things right.

Microsoft seems to have messed up again with its latest Windows 11 update, which borks the classic Outlook app. Earlier this month, classic Outlook struggled to open encrypted emails. Now, Neowin reports that several users are saying the latest Windows 11 update (KB5074109) has made classic Outlook completely unusable.

Microsoft has issued guidance to uninstall KB5074109 security update or switch to webmail after the patch caused Outlook Classic to freeze on Windows 11 systems.

Microsoft shared a temporary workaround for customers experiencing Outlook freezes after installing this month's Windows security updates.
