Error code 1429 when trying to email contribution statements

[lynnmarsh]

I am trying to email contribution statements for the first time. I was testing my own as well as trying the entire congregation. I keep getting the same error code Code: 1429 Method: create email file. I have set up the email defaults in the Email under User Setup as well as entered them when going through the process of emailing the statements. I do not require authentication as my Outlook does not have this checked. I entered in my outgoing server as the same as is set up in Outlook. Has anyone encountered this same error code? I would really like to email statements to those that have email rather than stuffing envelopes quarterly. Thanks for your help.
