Outlook, Teams and Copilot crashed in 74 countries for more than 20 hours. Microsoft says it wasn’t a hack, but it still can’t name the cause. One company shouldn’t be your only lifeline. Set up backups, starting with a free Gmail address. Swap personal emails and cell numbers with your manager and top coworkers.
Put key contacts in your phone’s Contacts app, not just Outlook. Write a one-page “email’s down” plan: who calls whom, which backup address customers use and where shared files live.
