Azure AD users sign-ins keep repeatedly locked out
Dear Tech's, I'm facing issue that few users are keep getting locked out and sign-ins trying from different countries. How to prevent and what's the best way to suppress it. Advance thanks for your suggestions.
- amuru15Copper ContributorThank you! l will check if any legacy authentication.
Best thing to do is disable basic authentication across the board and/or turn of legacy protocols such as POP/IMAP/SMTP, which are what usually "brute force" attempts use.
