Re: Sending email from an alternate email address (same office 365 domain)

Hi Aaron,

I tried to setup a test distribution group before deploying everything to a user, and so far, things don't work well for me.

Here's what I'm getting.

First of all, I've added a new distribution group ("testing"), with myself ("mkornienko") being a member.

Then added permissions to SendAs from PowerShell. And here's how output looks like:

PS C:\Windows\system32> Get-RecipientPermission "testing"

Identity                Trustee                 AccessControlType       AccessRights            Inherite

--------                -------                 -----------------       ------------            --------

testing                 mkornienko              Allow                   {SendAs}                False

Also, actually, there doesn't seem to be a need for PowerShell after all, as it seems to be possible to add SendAs permission from the new Exchange admin center > Groups UI

(Groups > Edit > Open Group Properties > Group Delegation > Send As).

I have also confirmed myself being in the list there as well (screenshot here: https://dl.dropboxusercontent.com/u/296505/Distribution%20Group.png )

With that set up, when I try to send an email as testing@<ourdomain> user (using my mkornienko account, and switching the "From:" field of outgoing email in Outlook 2010  (New mail > From : Other E-mail address : testing@<ourdomain> ), I'm getting the following bounce:

Your message did not reach some or all of the intended recipients.

      Subject:Testing from testing@<ourdomain>.com

      Sent:5/13/2013 9:24 PM

The following recipient(s) cannot be reached:

      'mike@<recipientsdomain>.com' on 5/13/2013 8:24 PM

            This message could not be sent. Try sending the message again later, or contact your network administrator.  Error is [0x80070005-00000000-00000000].

Not sure what I'm doing wrong. Could you advise?

Thanks!

Mikhail.
