Hey there! I've multiple alias configured for my outlook mail account, which I can use to receive and send emails (on web). On Thunderbird after configuring my primary account, I'm unable to find any option that would enable me to send email using an alias. It tends to use my primary email address. However I do receive separate emails for each alias in different folders configured for them (subscribed folders).

How to use an alias to send email? In write-email box, the "From" drop down list doesn't contain any alias.
