In 2020, we added a PIN-based verification step to our existing phone-based verification process, to better protect your organization. If you call support, the Microsoft support representative will send a verification code to your registered email or phone in your Admin Center profile. Provide this code to the support representative to grant them access to your organization’s account.
[How this will affect your organization:]
This change will be enforced as of November 1, 2023
[How this affects your organization:]
Starting November 1, 2023, this enhanced verification will be required to open and manage a phone-initiated case with Support.
[What you need to do to prepare:]
To help ensure an expedited Support experience, users with appropriate permissions can update their profile contact information in Admin center->Users->Active users->Admin Name->Manage contact information.
