Hello Tim,
unfortunately this is a known issue we can not do anything about it. Outlook does not support the use of Aliases from external Mail Clients, only from it’s webmail.

Same Problem here, bad so emclient is useless to us…
senders email address ist shown like [email protected] instead of [email protected] (this is the primary alias in outlook.com)
