Question Marks ? Appear in Sent Emails

Thanks for the swift response, Ernie. Let me add this observation:

The character which Outlook places at the end of the sentence only appears if there's a space before the return. Using number symbol for space, here's what I send:
----
Sentence 1.#

Sentence 2.

-----

What gets sent back from the Outlook user is:

Sentence 1.Â

Sentence 2.

The evidence is that the combination of space and return causes this random character; and the suspicion is that double spaces trigger the question mark. Simple, though unsatisfactory, solution: don't have a space before a return, and don't use double spaces.

In response to your question, my prefs in Mail prefs / Composing : Responding are:
Use same message format as original message : Unchecked
Quote text of original message: Checked
Increase quote level: checked
When quoting text in replies or forwards: Include all of the original message

Luke,

Please test without checking to increase quote level. What I am suspicious of the colored, vertical lines that are added with increased quote level, but I don't have a quick way to test this. My one PC is using Thunderbird.

I think the increased quote level brings in Rich Text that Outlook does not handle well.

Anyone have any updated information about this? Does 10.4.5 address this?

Are you using 10.4.4 or 10.4.5? I called up Applecare and they want to know. It might be a conflict wiht 10.4.5 and Outlook. Thanks.

Ernie:

All of my accounts are POP3. Everything is local.

In response to having Display Remote Images checked, in the emails that I have been testing contain no remote images. They are RTF emails.

Ernie,
Thanks for your interest in my problem.
I have a POP account.
I called and emailed AppleCare support as well.
Thanks.
Peace,
Glen
