Cause

This problem occurs if the e-mail activity that you sent has more than 999 continuous characters in the e-mail activity message body.

Some e-mail systems use an unsolicited commercial e-mail (UCE) filter that may be configured to reject e-mail activities that have more than 999 consecutive characters in the body of the e-mail message. A Microsoft CRM e-mail activity may be rejected by the UCE filter in the recipient's organization if either of the following conditions is true:
  • The message body contains more than 999 consecutive characters.
  • The message contains no line feeds or carriage returns.
Note Unsolicited commercial e-mail is also known as spam.
