Are they on some kind of limited bandwidth data plan? They may be getting throttled and the download speed is so low it's timing out. Also, are they out of hard drive space?
</div>


<div>
Is it a public service that is being used? .. I think you were on the right track with what you were doing above:<br />
<br />
<br />

<blockquote>
 I have changed ports, tried SSL, created a new email address, created a new data file, created a new profile
</blockquote>
<br />
It is very possible that the hoster changed some of the security or port settings without letting you know.<br />
<br />
If you are able to log into the server and receive but not send then that would indicate that there is a problem with either security or the mail server you are attempting to connect to.<br />
<br />
Something else you may not have tried, most services that have POP enabled have IMAP enabled as well.. Maybe you should try to connect to the IMAP server using the ISP's help pages and see if that server works or if that is failing as well.

First of all, thanks for thinking outside the box. Wiiliam, not limited bandwidth, and just checked the HD--plenty of space.<br />
ITGuy565, I have 80+ other users using the same email (1and1) no other problems reported.<br />
I just tried setting up IMAP. still the same issue. It actually reports an error when trying to sync the inbox. <br />
The current error is 0x800CCC0B
</div>


<div>
Is it related to a specific email maybe?

Make a new, test Windows User Profile (Account). Log into the new Windows Account and set up Outlook. Does it work now?<br />
<br />
Note: &nbsp;Windows Profile is not the Outlook Profile (which you did make a new one).

Not related to a specific email. &nbsp;I have created a new email account, created a new profile, data file, etc..
</div>


<div>
John, I created a new Windows Profile. Same problem.
</div>


<div>
Thanks for the update. I would back up the machine, reinstall Windows and then the software. Windows 7 is getting quite old now, and there are probably things gone wrong in this computer.
</div>


<div>
Looks like you have tried everything but a Repair Install of Outlook.
</div>


<div>
Just did a repair install. &nbsp;Still the same issue.
</div>


<div>
You said it is a VERY remote user...what do you mean by that, exactly?
</div>


<div>
Just not a site I can visit. &nbsp;7 hours from our corporate office.
</div>


<div>
This might be a silly question but is the user out of hard drive space where the PST file is located?
</div>


<div>
Not a silly question, but something I already checked. Not out of HD space. Thanks
</div>


<div>
and is the pop server in outlook the correct one?
</div>


<div>
Nobus, Yes. &nbsp;I'll take any suggestions, but I have checked that several times. &nbsp;The strange thing is it connects to the pop server just fine, just won't download new messages. If there are no new emails on the pop server inbox, then outlook completes the send/receive with no errors.
</div>


<div>
did you try sending &nbsp;amail to yourself?

Windows 7 with Outlook 2016.<br />
This is a VERY remote user that POPs email.<br />

Outlook will send just fine. &nbsp;The strange part is that Outlook logs into the POP server just fine. &nbsp;<br />
I know this because it passes the send/receive test on initial setup. And, I can log into the account online, move all of the new messages out of the inbox, and Outlook completes the send/receive. &nbsp;It only gets stuck when it is trying to download a message.<br />
