My note 3 below shows how to send to a snapshot which may be the crux of your problem.
In a corporate environment, my initial testing of GFI faxmaker (
shows some promise for portrait report. I had several issues setting it up but seemed to work once I bothered tech support and got answers (the documentation and setup routine for NT 4.0 Exchange 5.5 leaves something to be desired). I think I'm out of the trial period and it quit working for me, I think I'll be registering it. In my browsing this seemed to be the cheapest solution for a small company (25 user license).
Notes:
1 Faxmaker does not support faxing landscape documents (it squishes landscape to fit)
2 To get everything to work I had to send to a snapshot format and load the snapshot viewer on the server. This is not a supported feature by Faxmaker but worked for me.
3 Code to send to Snapshot; this is a modification of what I had in code. If there are errors the important thing is that the Snapshot format is specified correctly:
DoCmd.SendObject acSendReport, strReportName, "Snapshot Format (*.SNP)", strTo, , , strSubject, , False
