Allow users to use unsecured port numbers such as 25 with SSL connection as some organization require this or have it enabled.
Need the ability to use unsecured port numbers (like 25 or 110, etc.) with SSL connection due to the settings implemented by the IT Admins or requirements setup at the Server level. Other email clients allow this feature and having this enabled will help a lot of users.

Having migrated from outlook for windows to mac I assumed the capabilities would be basically the same.... now I cannot even send mail unless using an internal IP which is pretty useless as I travel for work. Outlook is useless to me and I will have to use Apple Mail until this is rectified.
Additionally, it took 11 days for MS support team to give me this answer.
