Microsoft published a support document that, at the time of writing, was most recently updated on July 29. In it, the company warns that emails containing “complex tables” may cause the Outlook application to freeze, forcing the user to end the task within Task Manager and then restart it to regain access to their inbox. Microsoft calls out emailed ride receipts from Uber specifically as a bug trigger, though some other emails that feature these tables have also been found to cause the application to crash. As if that weren’t annoying enough, Microsoft says some tables are also causing Word to crash.
The bug is impacting users in both the current channel and current channel preview, as well as those using a beta version of the software. Microsoft is, of course, working on getting a patch out that will fix the problem, but until then, you’ll either need to avoid content that causes the software to freeze or, if you’re particularly desperate, roll the application back to an older version. If you’re experiencing the bug on your work computer, it’d be best to ask IT to implement the rollback, but if you’re on your own, you can find instructions on how to do that in Microsoft’s related support document.
