Some users can't send email

Need some help on this.

Running windows 2003 Small Business server, for a couple years now, and I've got roughly 10 users on the system, most are for email only (never could figure out how to create an email account without allowing local log-in)

Anyways, 2 accounts for sure can NOT send email through Outlook express no mater what I do.

I've got several accounts that get used daily, I've got the server requring username/password to send email, however

My Administrator account goes to send, and I'm asked for username and password (when requiring authentication is enabled) after I enter it, it pops up again asking... I have one other account that I created recently that does this.

I'm guessing this must be some setting or something specific to these accounts as other accounts work perfectly, on the same computers, I've checked the users in the Active Directory Users against known working ones, all settings appear the same... I've checked the settings under "accounts" in outlook express again all the same, but for some reason these 2 accounts can not send mail through outlook express, they can through Outlook Web Access, but not express

For the one account its just anoying that I can't figure it out, however the Admin account is one I use, and am unable to send through it, I'm forced to use my other accounts I don't want known to people.


I posted this elsewhere on the web as well, and so far got told I should be using Outlook, not Outlook Express, because of the added features, the fact that licenses came with SBS (which I still haven't found them, or how to use them), as such I'm currently testing it out on one machine, but may not be the solution due to the users I'm working with not being very computer proficient, they are used to using Outlook Express and know how to use it.

In addition, is there any way to add an email account for a user without making them a user of the system/network... all my accounts have been created through the active directory and all are listed under my SBSusers area, all have access to network resources just like the admin account and accounts created for the local computers... I need about 10 email accounts, but only have 4 computers logging onto Server resoures (hard drive shares)

Please help.

The pop3 and smtp server are the same box? Did you check the smtp server configuration on the outlook express for the account that are no working?
Can you receive e-mail from those accounts?

 

have you checked whether all IP address is granted for relay purpose?

check your smtp protocol
