Making Outlook aliases work

[digitallysane]

@Michal_Burger

I have some rather good news. We’ve done some testing and found out that once SMTP is used for sending instead of AirSync, the “From” address is not replaced and it works as expected. As the Microsoft finally fixed the autentication issue with SMTP, SMTP can now be used for sending via outlook.com.
That behavior (send via SMTP instead of AirSync) can be achieved with adding this key to registry settings:

UseAirSyncSendMail DWORD 0

Checked on the office computer today and I can confirm that this works.
Thanks @Michal_Burger !
