Microsoft has acknowledged that the latest Patch Tuesday updates for Windows 10 version 1909 (November 2019 Update) has a bug that is preventing some users from logging into some Microsoft 365 suite of desktop apps like Teams, Outlook, or OneDrive for Business. The company updated the knowledge base article KB5003169 (spotted by BleepingComputer) to detail the issue and provide a possible workaround. It has also updated the known issues documentation for that version of the OS on the release health information page.

The Redmond firm notes that some users might be served with a “We ran into a problem. Reconnecting…" message or an error code '80080300' when trying to log into the mentioned apps post the restart initiated by the update. The issue might be resolved for some through a simple second system restart. However, the trick might not work for all users facing the issue. The company recommends that those users log into the web versions of the offerings or the clients on other operating systems, if possible, since those are currently not affected by the bug.

The firm says that it is investigating the issue and that it will provide an update in the “upcoming release”. It is not clear if this means that a possible fix might be made available via an out-of-band update as soon as it is ready or if it could be served as part of the optional C/D releases later in the month.

Windows 10 version 1909 is no longer supported for consumers and will only be serviced for users running Enterprise and Education SKUs. While the OS is currently running on around 11% of total Windows 10 PCs, the holdouts are likely enterprise customers, who will especially be affected by the issues caused by this month’s Patch Tuesday updates. Currently, those affected can switch to the web versions of the offerings, which is the only known workaround.
