If everything is imported matching the POP3 provider, I would just do it now. because it will be transparent.

On that note, AFK for lunch.

Agreed, as long as the settings are all the same, computers on the internet won't really see a difference.

Here's a question that will help determine if you need to do more for autodiscover to work.
Let's assume your domain is acme.com for email
What is your domain name inside your network?
If your domain name is acme.com, then you will need to add a DNS entry internally to your DNS server for autodiscover just like you did at cloudflare.
If your domain name is something like acme.local, then you need to do nothing.

I noticed CloudFlare did not bring over autoconfig and autodiscover of the POP3 provider DNS settings...will add those with my autodiscover for O365.

Hit a snag...when adding the O365 autodiscover, it gave me this message:
You cannot add a CNAME record when there is already an A, AAAA, or CNAME record with the same 'name' value
The original autodiscover is an "A"...

How long ago did you add them? Assuming there is a poll feature in cloudflare so you can repoll the old DNS hosts, that should pull them, but personally, I'd simply open two windows side by side and compare, any that are missing, just add to cloudflare manually.

So it is there. perhaps on a different page.

I had to manually enter the autodiscover info from the existing POP3 provider into CloudFlare because it didn't carry over...did that...went to add the O365 AutoDiscover info and that's when I got the error...
And both were entered autodiscover.domainname.com
-
Wondering if I should make the name autodiscover.outlook.com as well as the value, since I already have that autodiscover....or will that not work?
-
I've made the move to CloudFlare...just going to have to fix this autodiscover problem with O365

This won't work.
When you configure Outlook it takes your domain name for example [email protected] and looks for a DNS entry at autodiscover.acme.com -

OK hold on a second.. was there an autodiscover record in your old POP3 CP? was it something like A record Autodiscover xxx.xxx.xxx.xxx?
If so, you can't have two records with the same name. That old autodiscover record points to your old POP3 setup... You'll need to delete that record and create a new CNAME pointing to the one provided by O365.
This shouldn't affect anything because the clients that need to talk to the old POP3 are already configured to connect to it (though I suppose that for some craziness, they could be trying to pickup mail from autodiscover.acme.com, and if that's the case, you will break receipt of new mail from the POP3 provider).
Please confirm this by looking at the settings in one of your preconfigured Outlook clients.. what is the server name for POP3 and SMTP, make sure it's not autodiscover.somethingorother.com

Correct...I brought over the old Autodiscover pointing to POP3...so it is safe to delete, add O365 and we can still receive POP3? And thanks for the patience...would rather be safe....

They are all pointing to mail.domainname.com...so should be safe to delete and add the O365 autodiscover...

What is interesting now, is after I moved to CloudFlare and added all but the MX from O365, waited 15 minutes and clicked next in O365, it said it found the info except for MX records and autodiscover. However, a check of all my O365 records now show X's, even 30 minutes later...wonder why I found it at first (after 15 mins) but not now...

From your test machine, open a command prompt and type ping autodiscover.xyz.com does it resolve to outlook.xyz.com and then an IP?

Still points to the POP3...assuming it is still propagating...though I thought the SRV records would be updated by now...

As always I highly recommend that DNS not be tied to a Registrar. The system is designed to protect you and putting the two together eliminates a critical separation of duties.
Given that better DNS providers are free, why use the registrar?
My recommendation is CloudFlare.
I'm only working toward moving DNS back to his registrar for simplicity - I do understand your point on the separation.
No simpler. More complex most likely. CloudFlare is so easy and has such a nice interface.
