Select whether you would like to secure access to the G DATA 365 | Mail Protection with a client secret or a certificate. For security reasons, we recommend using a certificate in all cases.

If you would like to manage the quarantine of the Microsoft Exchange Online together with the quarantine of the G DATA 365 | Mail Protection via our interface, the use of a certificate is required.

Enable the toggle switch for the Microsoft quarantine if you would like to manage the quarantine of the Microsoft Exchange Online together with the quarantine of the G DATA 365 | Mail Protection via our interface.

If you have decided to use a certificate, upload the PFX file you created from the directory used when creating it. Otherwise, enter your client secret.

5.

Use the Test button to test whether access is successful.

If you are shown an error message regarding an invalid certificate, check the password used again.

If the test has confirmed a valid certificate, click Next.

If you followed the setup guide, you should receive the following confirmation on the next page that all permissions have been granted correctly:

G DATA 365 MailProtection: Confirmation that permissions are present

If the permissions have not yet been granted in full, you will receive an overview at this point indicating which permissions are still required for the G DATA 365 | Mail Protection. Before you can continue, these permissions must still be granted in Exchange Online.

G DATA 365 MailProtection: Permissions not present

If all permissions have been granted correctly, click Next.

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

You can close the window and continue with step 7 at a later time. The mail server is already present in the overview. The server setup can be reopened and completed at any time via the BearbeitenStift.

On the following page, check the domains that are being checked by G DATA 365 | Mail Protection.

MX record configured

This display indicates,
no = …​ whether the MX record points to Exchange Online,
or
yes = …​ whether it has been redirected to the G DATA 365 | Mail Protection.

Here you can see whether the domain is linked to the specified Microsoft Online account and whether it has been verified by Microsoft. This prevents outsiders from sending email via your Exchange Online. In this column, your domain must be verified with yes.
Otherwise, email cannot be accepted by G DATA 365 | Mail Protection.
