Rules for Aliases in Office 365

I found out this week that it is not possible to create a rule for email sent to an alias created in Office 365.  If you wanted a rule that would file emails into a folder based on which email address it was sent to then you can't simply use an alias to do this.

What you need to do instead is:
1. Create a distribution list named as the alias (e.g. accounts@organization.biz) with the intended recipient in it
2. Make the distribution list accessible from outside the organization
3. Create the rule based on the distribution list

I hope that helps some of you.
