Outlook cuts off ending of email addresses

[Bine79]

Hi!
I am using Outlook 2007 with Vista and since a short while ago I cannot send
any messages from one of the two accounts (from different email servers) I
have set up. When I type an email address and make extra sure there are no
typos and then click "send" I immediately get a message that the email
address was not valid and the address displayed in the error message is
lacking a couple of letters at the end. Example: (e-mail address removed) comes
back as john.smith@ms
Does anybody have an idea where that problem stems from? Is it Outlook or my
server?
Thanx in advance

Is the "message" a popup dialog window from Outlook that displays on
your screen, or is it an e-mail that gets sent back to you that you read
inside of Outlook?

What does the recipient's e-mail address look like in the copy that was
saved in your Sent Items folder in Outlook?

Yet tried disabling the superfluous e-mail scan function in your anti-
virus program? What AV program do you use?

Is (e-mail address removed) (as an example you used above) your e-mail address
or is the recipient's e-mail address? If it is your e-mail address then
check the problematic e-mail account defined in Outlook. You may have
misspelled your own e-mail address in the E-mail field.

Hi VanguardLH,

here the info you requested:

Is the "message" a popup dialog window from Outlook that displays on
your screen, or is it an e-mail that gets sent back to you that you read
inside of Outlook?

it is not a popup dialog but an email from "System Administrator" (not
further defined) with the subject "Undeliverable:title of undeliverable email"

What does the recipient's e-mail address look like in the copy that was
saved in your Sent Items folder in Outlook?

when I open the mail from the folder Sent Items the addresses are all like I
wrote them originally but interestingly in the error message all that appears
is my own sender's address. For example I send from (e-mail address removed) to
(e-mail address removed) and the returned message says:" '(e-mail address removed)' on
07/07/2009 22:57
504 5.5.2 <bine79@live>: Sender address rejected: need
fully-qualified address" so somehow on the way the real recipient's address
gets exchanged for my own sender's address which is always truncated

Yet tried disabling the superfluous e-mail scan function in your anti-
virus program? What AV program do you use?

I use Kaspersky Internet Security 8.0. Haven't yet looked there but I will.
I f that solves the problem I'll post it here

Is (e-mail address removed) (as an example you used above) your e-mail address
or is the recipient's e-mail address? If it is your e-mail address then
check the problematic e-mail account defined in Outlook. You may have

see second answer above about this, I don't know is this is relevant but
receiving from that account still works fine

Thanks for the pointer to the anti-virus programm, maybe I'll luck out.

problem solved, I've been sooo blind. It was the SENDER'S address that kept
being rejected because for some reason it got changed in my account settings.
I only realized it after re-reading my answer to your post, VanguardLH, so a
huge THANKS to you!!!

it is not a popup dialog but an email from "System Administrator" (not
further defined) with the subject "Undeliverable:title of undeliverable email"

Then the receiving mail host was sending you an NDR (non-delivery
report) as a new e-mail to tell you about the problem. They didn't like
your e-mail because of invalid syntax in one of the headers.

504 5.5.2 <bine79@live>: Sender address rejected: need
fully-qualified address"

There's the clue. You are the sender. YOUR e-mail address is invalid
(it is incomplete). As you mention in your next reply, you misspelled
your own e-mail address in the account parameters defined in Outlook.
The TLD (top-level domain) of ".de" was missing.

Odd that this problem just cropped up (i.e., that your setup was working
before and this was a new problem rather than this problem always
existed since you defined the account in Outlook). Either you were
fiddling around with this account's settings in Outlook or you recently
installed something that modified Outlook's accounts.
