`Add external addresses` option does not exist
Hello. I was trying out Mailbox, and was hoping to set up my email account to use my own custom domain. But i cannot complete the first step of the guide, because the described option does not exist for me.
The guide on: https://kb.mailbox.org/display/BMBOKBEN/Using+e-mail+addresses+of+your+domain says:
Step 1: The mailbox.org security key Log in to your mailbox.org Office and go to mailbox.org Settings in the settings area. The ‘Add external addresses’ option is available under ‘E-mail Aliases’. Enter the desired e-mail address.But for me, that option does not exist.
Is this only because i'm still on a 30-day trial? I have tried to add some credit to my account balance to test, but still nothing.
