I've been poking around the forums and I see a lot of items around SendAs permissions, but this one (AFAICT) hasn't been asked yet:
I have a non-Office 365 email address assigned to me by an email forwarding service (Say...lee.nomail@nospam.net). I can point this forwarding service to deliver mail to Office 365 with an issue, but I'd like all outgoing email to have the From field to have lee.nomail@nospam.net so receipients don't get "Sent on behalf of" and when they hit reply the mail is sent to the forwarding service.
Can this be done in Office 365, and if so how?
Hi C.A. Dahl,
Thanks for your reply on the forum.
Hi Lee Brink,
If you would like to send messages from a non-Office 365 account directly in Office 365, one option is to add this account as connected account. However, for connected account, if you send messages from this account, the sender field would be as "your Office 365 account on behalf of your non-office 365 account."
If you do not want to have the "on behalf of" in the sender field, another option is to verify your domain in Office 365 and make it an Office 365 account.
Just for your information, Send As permission could only be applied to Office 365 accounts, you could assign Office 365 users with send as permission to send messages as another Office 365 user, however, this could not apply to non-Office 365 users.
Here are some links for verifying domain in Office 365:

Hello Lee,
In order to prevent domain spoofing issues, if you want to be able to send from a domain address without the "on behalf of" statement, you have to first verify the domain with O365, then add the address as a proxy address to an O365 mailbox.

That seems straight forward enough, but being ignorant of the verify process could you give a brief description? Is it like a typical activation email or more like verify I own the domain? The former would be pretty straight forward and easy to do; the latter impossible.
Ok, so it's not like Exchange where a proxy address can be put on an account and set to the PrimarySMTPAddress. And it sounds like if I'm using an email forwarding service there is no way to pass verification.
Not what I was hoping to hear. That makes Office 365 unusable for me.
