BD Is Blocking My Microsoft 365 Outlook Email. Started last week. Can it be fixed?


I saw the answer to this question in January but do not understand what exchange to make an exception in phishing?



  • Hello @lamagazine and welcome to the Community!

    Are you using a VPN connection when this happens? If yes, check the article below for remediation steps to try:

    In the event the VPN is disconnected and Outlook is still blocked, you can temporarily disable the security modules one by one and check if the emails are unlocked after each deactivation. This procedure should help identify the module that blocks the app. Refer to the below article for detailed steps and don't forget to reactivate your defenses once the troubleshooting process is completed:

    Depending on the security module that interferes with Outlook, we can advise on the next steps.

    Let us know how it goes.
