I am using Outlook 2002 and Windows XPsp2, and have several email accounts which i have been using for some time, with different ISPs. I am able to receive emails from all, but am unable to send using my primary email account "firstname.lastname@example.org" (this is the only one I use as it is the default - I don't know how to send using the others - help req'd also!!). Note that the test facility sends mail successfully!!
I have recently removed Instant Messaging which i did not require/want, as described on the following thread...
The email failure appears immediately after hitting the send button after email compilation, but in theory it should not appear until the "send/receive" button is used!!
Here is the error message: System Administrator - Undeliverable:
"Your message did not reach some or all of the intended recipients.

Looking forward to your help/comments.
