imap and pop3 on exchange 2010

We currently have exchange 2010 server with outlook 2007/2010/2013/2016. I have been told to setup pop3 and imap for users on it. What is the best solution to accomplish this?

imap/pop3 services have been enabled. ports have been configured 25/587.authentication set to secure. Do i need to buy a x.509 certificate? i already have certificate how can i check if it is x.509 or not

How to configure it on client after setup on exchange 2010. Please list the steps for server and client

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

IMAP normally uses port 143. It usually encrypts at least passwords.
POP3 normally uses port 110. It usually does not encrypt anything, and SENDS THE USER CREDENTIALS IN CLEAR TEXT
POP3 also only allows a copy of the users inbox to be received, while IMAP syncs all folders.

Hardly anyone uses POP3 these days, due to the huge security risk and lack of support for syncing all folders. It is sometimes used internally, but hardly ever on the public internet.

Enabling it is pretty straightforward:
0. Advise management of the security implications of sending credentials in clear text fro POP3, get a written authorisation.
1. Forward ports 143 or 110, on your firewall.
2. Set the Microsoft Exchange POP3 and Microsoft Exchange IMAP4 services to automatic, and start them.
4. Use the EMC to enable POP3 and IMAP4 on desired mailboxes. (Recipient configuration, Mailbox, {mailbox name}, mailbox features.

You don't need to buy a separate certificate. Existing certificate for SMTP can be used too. Just enable the POp3 and IMAP services on it.
Most probably it will exist already.
