I contacted outlook IP service and they presented me with the list of email addresses to send validation link.
However, after my attempt to create user "email@example.com" MIAB responded it wasn’t possible and that I use alias instead.
How do I do that ?
PS All I want is to receive email from MS Outlook IP service, which presents only postmaster and abuse options.
Check your default ‘aliases’ list… You should already have an alias (and others) already created as firstname.lastname@example.org forwarding incoming emails to your default email@example.com email address
An alias hasn’t, It just forward all emails sent to it to the ‘destination’ email address inbox.
I guess outlook would send you a validation link email to your firstname.lastname@example.org then this email will be forwarded, by default, to your ‘alias’ email@example.com and again to your email address inbox firstname.lastname@example.org
As said… the email will be forwarded from ‘alias’ email@example.com to firstname.lastname@example.org (that it is an alias, too) and will be forwarded again to your email@example.com that it is your default email address inbox.
Pay a look to your aliases list in your admin panel to see all your, created by default, aliases and spend few minutes to understand them and how they work.
