Certificate Requirement for Mailbox Permission Migration

When Is a Certificate Needed?

If your migration setup uses Client ID, Tenant ID, and Client Secret for authentication, you'll need to upload a certificate to your Azure App Registration before mailbox permissions can be migrated. This step is mandatory only for this authentication type.

How to Set It Up

01

Get the certificate file

Use the link below to download the .cer file needed for this setup.

Download Certificate
02

Open your App Registration in Azure

Log in to the Azure Portal. From there, head to Azure Active Directory → App Registrations, and pick the app that's connected to your migration.

03

Upload the certificate file

Inside the app, click on Certificates & Secrets, then the Certificates tab. Select Upload certificate and choose the .cer file you downloaded earlier.

04

Confirm and finish

After uploading, the certificate gets attached to your App Registration automatically. This allows mailbox permissions to be transferred securely during the migration process.

Using Modern Authentication Instead?

If your setup runs on Modern Authentication, you can skip this entire process. Mailbox permissions will be carried over on their own, with no certificate or manual setup required.
