Using aliases - trial account
I'm testing out mailbox to see if it will meet my requirements so I have a trial account for 30 days. I have created the one alias I'm allowed however I do not appear to be able to send as that alias. I see that there should be a drop down upper left to select this (based on the FAQs) however only my mail identity is there.
Am I missing something or is it an issue with the trial accounts (makes it hard to test an alias out if that is the case!).
