Microsoft Exchange Online (EXO)
This page is only available in English.
The following list shows all approved and requested mail apps for Exchange Online.
The permissions and privacy policies of each requested mail app are checked. If app permissions are too extensive or data is not handled in accordance with ETH guidelines due to the privacy policy, the Cloud Service Center reserves the right not to approve mail apps.
Mail apps are generally approved, i.e., there is no self-registration.

GNOME Evolution (Gnome) | APPROVED | offline_access Calenders & Contacts Mailbox & Mail Tasks EWS.AccessAsUser.All User.Read User.ReadBasic.All |
Last update on | Only Linux client with full calendar integration! Linux Mail Client released Evolution requires a lot of permissions. One critical example is “Calendars.ReadWrite,” which potentially allows access to all calendars. Statement from documentation (Microsoft Graph permissions reference): Administrators can configure application access policy to limit app access to specific mailboxes and not to all the mailboxes in the organization, even if the app has been granted the Calendars.ReadWrite application permission. This means that EXO must ensure that Evolution cannot view all calendars! Last update: User.Read & User.ReadBasic.All have been added. These permissions are necessary for shared mailboxes. |
