Error Code 400

Hi AlexMuirVisuals and missyjo2323,

Thank you for reaching out, and sorry about the delay in response.

As mentioned, you get the error when sending the document from signature via the Acrobat Online account. Is that correct?

If so, please try clearing the cache and cookies for the browser. Try opening the account using the new incognito window on the browser or an alternate browser to check if you get the same results.

If the issue persists, check if the problem occurs while sending a particular document. If yes, check if the document is locally or on some shared network drive. 

Also, confirm if the issue started recently after making changes. It will help us understand the reasons that might cause this issue,

Please share the screen recording, as it will help us investigate the root cause of this behavior further.

Thanks,

Meenakshi

Error code 400 means probably that you do not have the right to send out something for signature. That happens on Teams and Enterprise accounts, but may also happen with an ill configured cell phone or computer or a blocking proxy or firewall. 

What is your subscription (individual, Teams, Enterprise), what is your Os and version, what is your Acrobat version.
