Microsoft 365 keeps asking me to sign in
A stale token or a clash between work and personal accounts is usually the cause. A soft reset is often enough.
Try this first
- 1Close all Office apps and any browser tabs on office.com or outlook.office.com.
- 2Open Windows Settings > Accounts > Access work or school. Is your work account listed twice or as 'connected to organisation'? Remove the extra entry.
- 3Restart the PC properly (a real restart, not 'Shut down' which on Windows is a sleep variant).
- 4Sign in to outlook.office.com first, before opening Office apps; the browser refreshes the token.

- OneDrive has stopped syncingThe cloud icon is grey or has a warning. Locally changed files are not showing up for colleagues.
