Phone lost or stolen
Do not wait. The faster you block the SIM and the work accounts, the smaller the damage.
Try this first
- 1Call your carrier and block the SIM immediately. An active SIM lets someone intercept SMS-MFA.
- 2Sign in at login.microsoftonline.com > My Account > Devices > mark the phone as lost. That forces re-authentication for the work apps.
- 3If you are seriously worried, ask your admin to issue a remote wipe.
- 4File a police report if stolen; useful for insurance, and possibly to trace via IMEI.
- 5Reset passwords for accounts you suspect were still signed in on the phone.
When to bring us in
Email us as soon as you can. We push the remote wipe, revoke work tokens, and check for any active sessions still open.
