(Communigate Pro)?

Yes, it's possible that Communigate is controlling the output format. One thing to try is adding a dummy POP3 account to the mail profile. You should then be able to access that setting.

I tried your suggestion of creating a POP account and indeed could access
that setting. However, when I sent a new calendar event invitation it still
included the winmail.dat attachment and was still unreadable by Thunderbird.
By the way, thanks for all of your help, Sue!

Sounds like it's under the control of your mail server, then. Maybe Communigate has a setting to make it more Internet-friendly vis-a-vis iCal.

FYI ... I think I figured this out. I had installed "WebEx Integration with
Outlook" which provided a new template or form for the meeting window. I
believe it also sent the invitation in RTF format, over-riding the Outlook
internet mail options and resulting in the winmail.dat attachment. I
uninstalled this program and it seems to have fixed the problem. Again,
thanks for your help.
