The handle is invalid

Has anyone ever seen this error using emClient to send attachments?

Using Communigate Pro Server for email.


I need to ask you if you are using templates or sigantures. Also if you could send us file called “Main.dat” on [email protected]

you can find that file in C:\Users\your name\AppData\Roaming\eM Client

with regards


Thanks for the response. The user uses a signature but I don’t think she uses a template. I’ll check and will also send you a copy of her main.dat file. This seems to happen every once in awhile when attaching PDFs to her message. She can usually delete the attachment and add it back and it sends. Does not happen with every send.
