Connect a Microsoft 365 account (formerly “Office 365”) to Zammad.

Email settings panel

Note

Microsoft 365 channels are a specialized kind of 📨 email channel.

This documentation part does not cover 🗝 user authentication.

If you’re already familiar with email channels, you can skip most of this—but watch out for the “Accounts” section, which has a few extra quirks due to Microsoft’s strict security measures.

👥 Accounts

Connect Zammad to your email provider so that it can watch your inbox, send auto-replies, and more.

(Self-hosted users may have already completed this step during new system setup.)

🗂️ Filters

Make sure new tickets show up in the right place with automated, if-this-then-that rules for all incoming email.

📜 Signatures

Customize signatures for all outgoing email.

⚙️ Settings

Manage options like:

  • set the “From:” address on system notifications

  • raise the limit on attachment sizes

  • modify subject-line prefixes (e.g., use “AW:” instead of “RE:”)

Hint

Want to manually edit email subjects or always copy parent messages into your replies?

Check the ✍️ Composer Settings.

📇 Header manipulation

Manipulate auto response behavior or incoming routing.

Warning

🤓 This is a very advanced topic.
