M365 Graph for inbound E-Mails

  • Used Zammad version: 6.5.2-1760355405.28ab46c4.bookworm
  • Used Zammad installation type: package
  • Operating system: ubuntu
  • Browser + version: chrome / edge latest

Hi,

we use zammad connected to a few shared mailboxes in our m365 tenant with graph - so far everything works fine.
We also use an e-mail firewall appliance which is also connected with graph and journals every e-mail.

With this firewall we are able to remove e-mails after delivery to all or specific mailboxes.
Since the graph connection, e-mails once “recorded” in zammad can not be removed afterwards - we tried with both options - leave messages in mailbox and without.

I am aware that this is no problem within zammad and more a problem with our e-mail flow and firewall integration, but is there an option to solve this behavior?

In my opinion, switching back to IMAP could solve this problem?
