Choose whether to secure access by G DATA Mail Protection using a client secret or a certificate. For security reasons, we strongly recommend using a certificate.

If you want to manage the Microsoft Exchange Online quarantine together with the G DATA Mail Protection quarantine through our interface, using a certificate is mandatory.

Turn on the Microsoft Quarantine toggle if you want to manage the Microsoft Exchange Online quarantine together with the G DATA Mail Protection quarantine through our interface.

If you chose to use a certificate, upload the PFX file you created from the directory where you saved it during creation. Otherwise, enter your client secret.

5.

Click the Test button to check whether access is successful.

If an error Alert about an invalid certificate is displayed, check the password you used again.

Once the test confirms that the certificate is valid, click Next.

6.

If you followed the setup guide, the next page should display the following confirmation that all permissions have been set correctly:

G DATA 365 MailProtection: Confirmation that permissions are present

If not all permissions have been granted, an overview of the permissions still required for G DATA Mail Protection is displayed here. Before you can continue, these permissions must be set in Exchange Online.

G DATA 365 MailProtection: Missing permissions

Once all permissions have been granted correctly, click Next.

It may now take some time (up to one hour) for the domains listed as Accepted domains in Microsoft Exchange Online to be retrieved and displayed here.

You can close the window and continue with step 7 later. The mail server is already listed in the overview. You can reopen and complete the server setup at any time using the BearbeitenStift edit icon.

7.

On the following page, check the domains that will be scanned by G DATA Mail Protection.

MX record configured

This indicator shows whether the MX record points to Exchange Online or has been redirected to G DATA Mail Protection:
No = …​ points to Exchange Online,
or
Yes = …​ has been redirected to G DATA Mail Protection.

Verified

Here you can see whether the domain is associated with the specified Microsoft Online account and whether it has been verified by Microsoft. This prevents unauthorized parties from sending email through your Exchange Online environment. In this column, your domain must be verified with Yes.
Otherwise, G DATA Mail Protection cannot accept emails.

Be sure to follow our connector configuration notes at this stage.

Next, you can optionally test whether sending email through G DATA Mail Protection works correctly. Once you select a recipient email address from the drop-down menu, the Test button becomes available.

It takes a moment for the result to be displayed.

You can also skip this test for now and proceed directly to step 10. The test can be performed at any time.
