Once it's removed from "email addresses" in the portal, its not shown against the mailbox user in powershelgl, but is shown against the corresponding msoluser. And there doesn't seem to be a command to edit that field.

Speaking to MS Support yesterday, we worked out that if we add the new user with a different address, the system allowed us to add the correct address after the mail account had been created and it all works.

The proxy address is still listed against the proper, and the old user, but mail is only delivered to the correct "emailaddress".

Gut feeling is that some info that was used in the old DirSync days is still showing in the system, and under certain circumstances is used for verification, but isn't actually used in day to day operations.

I'm sorted now, and if I get further ADSync related issues I'll push it further with MS.

Thanks
