Workaround to avoid duplicate content marking when using a third-party signature tool?

Copper Contributor

Hi team,

 

Been hitting my head against a wall trying to deal with Microsoft support, so I'm hoping someone here may be able to assist me more effectively!

 

We are adding content marking to emails when certain sensitivity labels are applied, e.g. 'Internal'. We've also started trialing a third-party signature tool (Exclaimer) to apply server-side and client-side signatures to outgoing mail.

 

Unfortunately, since implementing Exclaimer signatures, duplicate content marking is being applied to the emails. Based on the below thread and comment by ratzq, this has been previously logged with Microsoft and they advised it's a bug.

I'm wondering whether anyone has successfully implemented a workaround to avoid this problem, or can confirm whether there is still no known solution.

 

After spending several hours on calls with Microsoft support then being told the "behaviour is expected", I'm not optimistic. I also raised a ticket with Exclaimer, but they weren't able to help - and since it's the content marking which is appearing twice, as opposed to the signature, I don't believe it's anything they can affect.

 

Thanks!
