[solved] Adding Office 365 shared Mailbox


I’d like to add another shared mailbox to my zammad instance.
I do already run one live instance with 6 shared mailboxes.

On the second instance I added one shared mailbox successfully.
Configuring Incoming succeeds randomly - outgoing is always failing with: error 501 (5.1.7 invalid adress).

The tested settings are below. I tried changing the users from "user@tld.de" to "user@tld.de\shared@tld.de" forth and back.

Is there a way to “clone” an email-channel / mailbox w/o verification, and edit the entry after adding it unverified? Though I just have to edit the channels email adress? Can I do it via the CLI?



type: imap
host: Outlook.office365.com
user: user@tld.de\shared@tld.de
pw: ***
SSL: yes
port: 993
keep messages: yes

Host: smtp.office365.com
User: user@tld.de
password: ***
Port: 587

  • Used Zammad version: 3.1.x
  • Used Zammad installation source: package
  • Operating system: Ubuntu 18.04.2 LTS
  • Browser + version: Chrome 75.xx

Expected behavior:

  • Create Email-Channel of shared mailbox

Actual behavior:

  • fails randomly at inbox verification
  • fails always at smtp verification

Steps to reproduce the behavior:

Is this a new Feature that i can add shared Mailboxes from Office 365 into Zammad? I thought this wasnt possible?

It works, first you have to use an user with license, then change the eMail address to an shared mailbox.


Thanks @Joe, that was the workaround I was using and couldn’t recall.
