You receive a 500 error (server error 500) when attempting to send a document for signature to TaxFolder, from TaxCycle.
This issue occurs when the message in the email cover letter template selected when printing contains more than 1024 characters.
Shorten the text in your email cover letter to a maximum of 1024 characters.
We strongly recommend that you keep your emails short and put detailed information into the PDF file itself as email is not a secure form of communication. You can always create another letter template to add to your print set and include the relevant information as a cover letter to the PDF.
