Transport Rules not affecting emails forwarded at mailbox level

Hi JanMaz,

In Office 365, to prevent message loop, the Exchange Online inbox or transport rules sometimes will not work on forwarded emails.

To confirm your scenario, can you please tell me your exact email flow so I can confirm whether it is an expected behavior or an issue? Thanks for your time.

Regards,

Robert

Hi Robert,

Thanks for digging deeper.

The email flow is emails coming into *** Email address is removed for privacy *** has an account forward set for *** Email address is removed for privacy ***.

My transport rule checks for *** Email address is removed for privacy *** AND if SCL=6+ THEN appends Subject line with [TEXT]

So the flow would be:

Transport Rule appends subject line and delivers to mailbox

Mailbox account forwards to otherdomain un appended Subject line

We have tested "Keep a copy of forwarded email in this mailbox" On and OFF.

We have tested with Contacts, Shared mailbox and Regular mailbox - all Office365 accounts).

Hope this is what you were asking for.

Hi JanMaz,

Thanks for the reply.

What do you mean by "My transport rule checks for *** Email address is removed for privacy ***"? Can you please send us the screenshot for the transport rule your set? Meanwhile, is this *** Email address is removed for privacy *** an external email address?

Please send us the screenshot via private message. Click your name on the forum and select View private messages to access it.

Hi JanMaz,

Thanks for the reply.

Please do not use the auto forwarding feature but use the inbox rules to forward the emails.

Click settings -- Mail -- Inbox and Sweep rule. Create a new rule to apply to all messages and forward to the external mailbox. Please test it and let us know the results.

Hi JanMaz,

OK, please test it and let us know the updates when you have time.

Hi Robert,

I tested your suggestion and the emails that end up in the Junk folder are not getting forwarded.

Do you have a best practice established to accomplish the following:

1. Prepend Subject line with [TEXT] if SCL > 4

2. Redirect or forward (without FW: appended to Subject) All emails to other email account not within domain

Thanks!

Jan

Hi Jan,

Thanks for the reply.

If the SCL is larger than 4, it is the expected behavior that it will be in the junk email folder.

Sorry to tell you that there is no such transport rule as you mentioned. Thanks for your understanding.

Regards,

Robert
