If you need to enable POP3, you just need to run the below command.

Get-Mailbox | Set-CASMailbox -PopEnabled:$true

If you need to disable POP3, run the below command.

Get-Mailbox | Set-CASMailbox -PopEnabled:$false

My pop3 is enable. i can received the emails but unable to to sent the email.

What is the error you receives when you try to sends via POP3, take in your consideration most of ISPs (Internet Service Providers) blocking sends through POP3 with the default port for security reaso

What is the alternate way?

If you working with Exchange server, so you just need to work with the default protocol (MAPI) and RPC over Http, more secure than uses POP3 or IMAP.

If yo still need to working with POP3 protocol make sure that your ISP is allowing your mail traffic through POP3.

If you are able to receive emails, then there is NO problem with POP3 service/settings.

So, stop troubleshooting/checking stuff regarding POP3.

If you are not able to send emails, then the problem is due to Outgoing server.

I would check the below things:

What's the SMTP server your client is pointing to ? Is it the same (exchange server) ?

Can you telnet to the smtp (outgoing) server over 25 ?

If it's exchange server, then you may need to check on the receive connectors configuration.. (we have default receive connectors to receive emails from clients but I think that's on a different port 587..)

You may also need to check the authentication option for Outgoing server..

You can also try sending an email using a different email client like Thunderbird or something else just to isolate the issue from the client side.

I was have the same problem, solved by our ISP, they were blocked us to send VIA POP3.
