How to fix Teams sign-in error 80090311 in Windows?

Issue: Hi, I can't seem to be able to log in to Teams. I keep receiving an 80090311 error whenever I try. Teams is extremely important for my work-at-home routine so I need it to be fixed as soon as possible.

Solved Answer

Microsoft Teams is an integral collaboration platform that integrates seamlessly with Office 365, offering features that facilitate chat, meetings, and collaboration. This tool has significantly transformed how businesses and educational institutions operate, making communication and collaboration smoother and more efficient. The platform's alignment with other Microsoft applications ensures users can share, collaborate, and communicate without multiple application shifts.

However, no software is without its occasional hiccups. A prominent issue some users of Microsoft Teams face is the sign-in error 80090311. This error, 80090311, typically indicates an authentication problem, suggesting there might be a barrier in the communication between the user's device and the Microsoft Teams server.

One of the primary causes behind the sign-in error is the Trusted Platform Module (TPM). TPM is a component on devices that stores encryption keys vital for system security. An issue with the TPM, such as an outdated driver, can interfere with the authentication process, leading to the 80090311 error in Microsoft Teams. Resetting TPM keys might also work.

It's worth noting that while 80090311 can be a source of frustration, especially when trying to sign in for an important meeting or when on a tight deadline, it's one of the many errors that software platforms can occasionally present. However, with the right information and tools, these issues can often be resolved efficiently.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
