Hi, Steve R

Thanks for reaching out to Microsoft Q&A forum.

Please note that our forum is a public platform, and we will modify your question to hide your personal information in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data. 

Sorry for this frustrating experience that you're encountering. In order to assist you better, I suggest you provide me with more information related to this issue such as:

• Does this issue happen in all Microsoft apps (Teams, Outlook, Office) or only in specific ones? Is this a work/school account (e.g., ******@company.com) and do you know if your license is active?
• Are you signed into Windows with the same work account, or a different/personal account?
• Does it happen when you use other device to sign-in the same account?

Meanwhile, here are some workarounds you can try to resolve this issue:

• Sign out of all Office/PowerPoint/Teams apps.
• Clear cached authentication data:
  • Delete contents of this folder: %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
  • Open Control Panel > Credential Manager > Windows Credentials and remove any Microsoft/Office‑related credentials.
• Go to Settings > Accounts > Access work or school, disconnect your work/school account, restart the device, and reconnect it.
• Try signing in again via https://office.com to confirm credentials are valid.

Hope this helps. Feel free to get back if you need further assistance.
