I marked myself Full Access and Send On Behalf shared mailbox permissions. Then in the from field do not appear shared mailbox so i type manually in
other email address:
firstname.lastname@example.org and click ok. Then once i try to send i receive error:
Your message did not reach some or all of the intended recipients. Subject: test Sent: 2016.12.06 09:07 The following recipient(s) cannot be reached: My Name on 2016.12.06 09:07 This message could not be sent. Try sending the message again later, or contact your network administrator. You do not have the permission to send the message on behalf of the specified user. Error is [0x80070005-0x0004dc-0x000524].
My Global Address List is updated, but i do not see it in GAL. Previously there was a user with same email as shared mailbox, but now user no longer owns that mailbox adress, it is now renamed.
What am i missing here?
