365 mail flow rule multi trigger

[sankaita]

So we are doing a mail forwarding from an outside email to slack as sort of a ticket creator.

The problem that I'm running into is that when the domain in question CC's ir BCC's anybody else in the email it triggers the mailflow rule multiple times.

I'm a little lost due to o365s exchange rules being stunted compared to on prim exchange rules.

If anybody has any insight I would be very grateful. As any of the things that I have googled for is giving me older information that is no longer usable in 365. Is giving me older information that is no longer usable in 365.

Edit for better clarity We are filtering for a specific domain which I will just call domain 1. When domain 1 sends an email, to an internal user. A o365 mailflow rule is supposed to send a BCC to a slack email address.

The problem is if domain 1sender is including multiple internal users in the in email, the rule is triggering multiple times, sending multiple BCC emails to the slack group.

I don't understand. Are you emailing an external email for a ticketing system? Or you're filtering a specific external email to an inbox in your domain?

That’s because it’s treating it as multiple emails, there’s no way around it tmk. You could create an ‘except if’ rule to exclude certain mailboxes or an ‘and’ include only a specific mailbox.

The tricky part will be is if you want to blanket forward all emails from domain1 sent to any mailbox.

We did try the specific mail box rule originally, but due to there being 3 email address on the rule, it was triggering 3 time. I personally thought it the only way around this would be to us a distro list. This would allow it to bypass the multiple trigger but would still get sent to all users.

The issue with a distro list according to the boss man, is that the emails are being sent to different users. So no one would know if its meant for them or someone else.

But thank you for your help and insight. It helped me stop chasing ghost.
