why does email signature in transport rule apply more than once in one mail?

we have a client that use a transport rule to apply a signature, but when he sends a new mail it applies the signature twice or sometimes three times in one mail.  the client does have the same signature in Outlook, but its not set to auto apply on new or replying mail, the client has manually hit the "add signature" button if he wants to use the outlook mail.

it seems OK for everyone else in the organisation, its just this one person.

any help would be appreciated.

when you set outlook to add auto signature, your transport rule don't understand it as signature (it consider it as part of message body)and it actually add signature again as part of disclaimer
The problem is why outlook is unable to add signature automatically to new or replied messages, check that config at outlook level, if auto add checkbox is missing or any else?

Some users refuse to believe that a signature will be added automatically after they send their emails, so they add a signature themselves. First, I would check if it is not that - a quick look at the sender's Sent Items will tell if the signature has been added manually.
Next thing - you might need to add some exceptions to the transport rule. If you modify the rule so that it does not add the signature (disclaimer) when the body of the message includes a specific phrase from the signature/disclaimer - this has two benefits. Firstly - if someone adds a signature manually (you've mentioned that the signatures are the same), the transport rule will not add the next one. Secondly - the signatures will not multiply at the end of conversations whenever someone replies or forwards.
If you need more email signature functionalities, you could take a look at our signature management tool - CodeTwo Exchange Rules. This way, you can add personalized, automatic email signatures to users, make sure they are always under replies and forwards (and not at the end of conversation,) and more.
