How to fix
Microsoft Office error 58tm1
on Windows

I keep getting "Something went wrong. [58tm1]" error in Microsoft Office apps occasionally. For example, last time I got it when I tried to open a file via Word. Could you help me with this?

The "Something went wrong" error 58tm1 could be one of the most frustrating ones when using Microsoft Office applications, for it most of the time upsets the workflow by denying users access to some necessary documents. This error will appear more often at sign-in or when trying to open any of the Office applications such as Word, Excel, or Outlook. Users have reported sudden prompts indicating that something went wrong, accompanied by the 58tm1 error code, which hinders their ability to utilize Office services effectively.

The primary causes of the 58tm1 error are generally linked to authentication issues, corrupted cached credentials, or problems with specific Office-related plugins. Over time, cached credentials can become outdated or corrupted, leading to authentication failures when Office applications attempt to verify user identities.

Additionally, components like the Microsoft.AAD.BrokerPlugin, responsible for managing authentication processes, may encounter issues that result in this error. In some cases, incomplete installations or corrupted files within the Office suite can also trigger the 58tm1 error, further complicating access to Office applications.

To address this issue, several approaches can be considered. Clearing cached credentials ensures that outdated or corrupted login information does not impede the authentication process. Re-registering or deleting the Microsoft.AAD.BrokerPlugin forces the system to recreate necessary authentication components, potentially resolving the error. Repairing the Office installation can rectify any corrupted files that might be contributing to the problem. Additionally, signing out and back into Office applications refreshes authentication tokens, which may help in resolving the error.
