POP3 receive location is not able to connect to mail server

Question

I've added a receive location in biztalk sever console and I'm getting the warning saying it's not connecting.

I've checked the connection outside biztalk and it's working. Based on that the problem must be with biztalk console definitions or properties and not with the mail server or the machine.

Is there some definition that enables outgoing ports for biztalk console or something similar that could fix the issue?

Testing the connection:

Connection succeed:

The username and password are correct:

Setup of the location:

Warning I get:

  POP3 
       The POP3 adapter could not establish a connection with the POP3 server. This could be due to the following reasons: 
1) The POP3 server host and port information is incorrect. 
2) The POP3 server is not running or is not reachable due to network issues.

Answer 1

Check if any component is inactive with the command:

Get-ServerComponentstate -Identity <Entity Name>

If it is, activate it with the command:

Set-ServerComponentState -Identity <Entity Name> -Component <Inactive Component Name> -Requester HealthAPI -State Active

Note: If you don't know the name of your entity you can get all entities in the server with the command:

Get-MailBox | FL Identity
