If Outlook is crashing for you today, you’re not alone.
A number of readers have emailed in to say that Outlook, the company’s desktop client, had crashed following Microsoft’s monthly release of security patches on Tuesday.
Other users are experiencing a range of various issues, such as black screens and other errors.
“We are looking into reports from some customers who are experiencing difficulties with Outlook after installing Windows KB3097877. An immediate review is under way,” said a spokesperson.
Many on Twitter also pointed to the patch, also known as MS15-115), a critical update affecting all versions of Windows, as the one to blame. The patch fixes a series of flaws that could allow an attacker to remotely execute code on an affected machine by exploiting how the operating system handles and displays fonts.
Some users have reported that Outlook crashes only when web-formatted (HTML) emails are displayed.
Earlier, download links posted on the security bulletins point to files disappeared off the site, but returned by mid-afternoon.
After checking on a number of Windows computers including in the CNET Lab in New York, the patch was still available for download through Windows Update.
This isn’t the first time the software giant has suffered through buggy software patches.
Last year, Microsoft withdrew four updates as part of August’s Patch Tuesday and even recommended users uninstall one patch. The company said at the time only a small number of users were affected, however.
