Intermittent failure of sending and receiving email

I have an employee that was just moved to another state to open a new office.  He went with his new notebook with his email set up and testing just fine.  He called saying he could receive email but not sent it.  After walking through the settings, we verified everything and pressed the test settings option and all tested fine.  That was this morning and he continued and sent email this morning.  This afternoon he cannot receive or send email.  When we run the test settings option the first 3; establish network connection, find outgoing mail server(STMP) and find incoming mail server (POP3).  But, the last 2 options do not pass; Log on to incoming mail server (POP3) and Send test email message.  
How can you send email and receive for 1/2 the day and then it not work for the second half of the day.  I have had them reenter everything.  I even tried a different set up like my personal one and get the same response.

I added their account to my workstation and all checked out fine, all five points got a green check.

This employee is in a hotel connecting from their Internet connections.  

What could be causing this problem?

Greetings, SharonStys !

The intermittent behavior could be due to slowing of ISP email service. Disabling antivirus and/or increasing the server timeout could make the service less intermittent.

1. Register an important send/receive library file.  Go to Start > Run and type regsvr32 inetcomm.dll

2. Check if antivirus email check is slowing sending and receiving.  Disable it. Check if other programs running in the background is interfering. Disable one at a time the Firewall, antispyware, antispam, and all Norton programs.

3. In the account settings, Advanced settings, change the server timeout time from 1 min to 5 min

4. Check if outgoing mail server authentication is required. Select that option in account settings and use same settings as incoming server

5. Your ISP may be blocking port 25. Try using alternate port 587.

If no joy, you need to use your ISP SMTP server to send out emails.

6.  Check with email provider Tech Support to determine if server is having trouble.

7. See this troubleshooter for not sending

Best wishes!
