How to Prepend distribution group name in subject for all distribution groups

Question

Hi,

I see that I can create a rule to prepend something to a given distribution mail

https://learn.microsoft.com/en-us/exchange/security-and-compliance/mail-flow-rules/manage-mail-flow-rules#use-exchange-online-powershell-to-create-a-mail-flow-rule

But is there a way to create a rule to prepend [distribution group name] to all distribution groups of the tenant ?

Hi @Juan Cabrera Jamoulle ,

Yes, there is no built-in option to add different prepend subjects to the messages send to different distribution groups at once.

As a workaround, you can refer to this script to create rules for all distribution groups in bulk:

$DG=get-distributiongroup
foreach ($DG1 in $DG){
New-TransportRule -Name "Mark messages send to $DG1" -AnyOfToHeader $DG1 -PrependSubject "[ $DG1 ]"
}

 

In addition, many features of our current products are designed and upgraded based on customer feedback.

You can submit relevant design ideas in this forum: Exchange Server · Community (microsoft.com)

As such demand increases, the issue is likely to be released in the future.

Thank you for your understanding and support!

Hi @Juan Cabrera Jamoulle ,

 

To prepend different distribution group names for messages sent to different distribution groups, you need to set up mail flow rules for each group.

It is recommended that you create rules in Mail Flow in the EAC.

Hi @Aholic Liang-MSFT

Thank you for your answer.

So this means that it is not possible to create a global rule to decide that the subject in all distributions groups will be prepend by [name of the group].

I hope this option or rule will be add by Microsoft.
