Was bedeutet "Mailplattform"?

The mail platform of a project specifies for which mail service new permissions are created – Exchange or standard Mail (mailin). No permissions can be assigned for the other mail service.

Depending on the mail platform or mail service of an account, different web mailers as well as different settings are required when setting up a mail programme:

Good to know: If the project's mail platform is changed (e.g. to Exchange), the mail service and settings for existing accounts in the project do not change.
