Office 365: Error 80070005 to send-as from a Shared Mailbox

March 18, 2014 by Paulie 3 Comments

When trying to send email from a different address in Outlook on Office 365 you may receive Error 80070005 :

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

Subject:    test

The following recipient(s) cannot be reached:

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

Error 80070005 in Outlook when using Office 365 to Send-as from a shared mailbox or distribution group

 Quite a few people have reported that creating a new Outlook profile solves the problem but this did not work for me. I believe the cause of the issue in those instances is related to the auto-complete cache in Outlook.

Add the correct send-as permissions using Powershell to resolve Error 80070005

Even though I had already added the correct send-as permissions within the Office 365 web based administration system I decided to try adding them again within Powershell to see if this gave any different results.

After adding the permissions with Powershell I was able to send-as no problem at all and the error 80070005 ceased.

Adding send-as permissions with Powershell is easy and I have written a separate post on how to do it here

    Thank you … you gave me a hint what to do and it worked. The powershell command worked, though it said, that there was a permission already = which was a bit unreliable, as it didn’t work without the powershell command ๐Ÿ™‚

    Thank you

    OMG thank you for sharing this solution!!! I’ve been trying to figure out why new messages were bouncing from a shared mailbox, but as soon as I ran your PS command, BOOM! Problem solved! ๐Ÿ™‚

    I also received this exact message/error after setting up a new shared mailbox in Office 365. The problem was traced to checkbox for “Hide from address lists” It’s a setting in the EAC at the bottom of the General window for the specific user. As soon as I unchecked, I could open as another user and send as from Outlook with the from set to my new shared mailbox. This setting is not turned on by default.
