Gmail email POP3 issue using Outlook 2010 - Not getting then on pc when zoho mail is attached

Gmail and our outlook has been working just fine. Been using it POP3 for years, We need to keep the data files for security reasons.So we cant use IMAP 

When I originally set up the CRM and the mail, The outgoing was fine but nothing came in,

Then I found the trick to getting the 2 way email responses to work under the mail addon app.  The next day I realized something,, I had no new emails in my outlook,nothing changed I just attached the Zoho Mail app from the CRM to my Gmail emails POP settings.

When I went and looked, all the emails that day went in the zoho box and never made it on my PC.  So I checked the gmail app on my phone. All emails were there.. 

I then download thunderbird. Installed my gmail (it defaulted to IMAP) and BINGO there were all my emails..

Previously to this, I called support, and some rude guy said I should hire an IT to figure this out.... I dont think that's, since it probably a setting or something,,,,


So since I cannot use IMAP and MUST use POP3 accounts for our office pc;s...  
PLEASE WHAT DO I DO to get this to send mail to the CRM and for outlook to receive the messages????


THANK YOU
