@Atir_Tahir Hope you are doing well. This working fine with pdf. But in the case of word or excel, it is returning succeeded count zero. Please advice.

@abhratanu

We are further investigating this behavior of the API. Your investigation ticket ID is SIGNATURENET-3456.

Hi @abhratanu

Microsoft documents do not support removing exact Digital signatures from the documents in case if there are many ones.
The best approach with removing Digital Signatures from the Microsoft documents would be to call Delete method that expects SignatureType argument as parameters, like
signature.Delete(SignatureType.Digital);
See example here

But in any case the method to remove digital signature by one or many should return non zero values.
I will double check today and get back with results
Thank you!

@abhratanu, please be aware that this issue was fixed in GroupDocs Signature 21.5 release that will be published tomorrow morning on nuget and GroupDocs web site
