About Microsoft 365 / Teams problems

Microsoft 365 and Teams problems can affect a single app such as Teams meetings, Outlook or OneDrive sync, or sign-in for work and school accounts. Sign-in problems can come from a mix-up between a personal Microsoft account and a work or school account, which Microsoft treats as different account types. Microsoft's service health page covers Microsoft 365, Outlook and Teams, and administrators also see details in the Microsoft 365 admin center.

Official information

Microsoft 365 / Teams official status page (verified )

Our check and Microsoft 365 / Teams's own status page can disagree. We test from one location and read only the homepage response. The provider reports what it knows about its own systems, such as sign-in, apps or single regions. A site can answer our check while one feature is broken, and a regional problem can affect one location but not another.

Typical Microsoft 365 / Teams problems

An editorial list of typical problems, not based on live user reports.

  • Sign-in keeps looping If Microsoft 365 sign-in keeps reloading, clear cookies for microsoft.com, office.com and microsoftonline.com only and check that you chose the right account type. Guide: ERR_TOO_MANY_REDIRECTS
  • Access denied to a file or site An access denied message in SharePoint or OneDrive can mean your account has not been given permission, so ask the owner to share it with you. Guide: 403 Forbidden
  • Teams meetings do not connect If Teams meetings fail to join on one network, a firewall or proxy may block the media traffic, so test another network or ask your IT team. Guide: ERR_CONNECTION_TIMED_OUT
  • Microsoft 365 apps show server errors Server errors across Outlook, Teams or OneDrive at the same time can match an entry on Microsoft's service health page. Guide: 503 Service Unavailable
  • OneDrive files do not sync When OneDrive stops syncing, check that you are signed in, that storage is not full and that file names do not contain unsupported characters.

General fixes: Productivity

  1. Copy unsaved work first Before you reload a page with recent edits, copy the text you just changed. A reload can discard edits that have not synced yet.
  2. Wait for the saved indicator Productivity apps show when changes are not saved yet. Wait until the app says saved or synced before you close it.
  3. Turn on hardware acceleration Some design and whiteboard tools draw with your graphics chip. If the canvas stays blank, check that hardware acceleration is on in the browser settings.
  4. Separate personal and work accounts Being signed in with a personal and a work account at the same time can open the wrong workspace. Use a separate browser profile for each account.
