Exchange Online Migration From POP3

Once you do step three, your old email system is cut off from receiving email. DNS determines where email goes. Once you change that, you've switched over.
That's not correct.

- create new local Outlook profiles for everyone
a) connect users to O365
b) attach POP3 account to profile, delivery of the POP3 items needs to go to Office 365
c) Import contacts only from PST to O365 (contacts alone won't take but a min or two on average)
d) attach their PST file to that profile (they'll have two sets of inboxes, sent mail, etc, but at least they will have access to their old email)
e) TEST
Doing step three didn't change the MX record that comes in step 4.
You can do everything including step 3. But once you do step 4, the email will start being delivered to O365, not the POP3 provider.

I might add that I hate Network Solutions. They are a horrible web host. Their portal is hard to use. The cost is stupidly expensive compared to pretty much everything else out there.

Well, my "free training" got rescheduled...AGAIN...LOL...but I think I am on my way...looks like a lot of work this Friday night though...
Question - I don't remember if this was discussed earlier but should I expect SOME lost emails? Basically, before I move to O365, I will to one, final download of email to the users PST file before moving the PST to the cloud...I should expect any emails still going to the POP3 while it is still up to still go there and perhaps I won't be able to retrieve them, correct? Just wondering what will go on during the crucial DNS and set up period...

I am looking at cloudflare for the DNS move this weekend...

You can move directly from the POP3 DNS to cloudflare.
Process- create cloudflare account
- create duplicate records in cloudflare to those in the POP3 control panel
- in the network solution control panel, change the DNS providers to the cloudflare IPs.
finished.

There's no reason you should lose any emails if you setup the Outlook accounts to have both the POP3 and O365 in them.
If you follow my setup, and have all new messages (after the first visit to the desktop) delivered via Outlook to the O365 account, you won't have to worry that any new messages sent aren't in the PST, because they'll already be in O365.
As soon as you make the DNS switch, you could start visiting the workstations immediately, this time uploading the PSTs to O365, but you wouldn't want to remove the checking of POP3 mail for at least 7 days to ensure DNS propagation.

Excellent...thanks....about to head into step 3 with my account right now...

Of course you can. But the Network solutions DNS seemed to already be setup, all he would need to do it take control back. I personally would just move them to CloudFlare first also, but I am comfortable with changing DNS stuff.

Step 3 Question real quick. When I connect users to O365, it will be my domainame.onmicrosoft.com account right and it will ALWAYS be that, even when DNS moves?

If your DNS is setup right with the autodiscovery url, you can use your correct domain name now, because that will not affect delivery of your mail. That is the MX Records. And since POP3 does not use autodiscovery, it will not cause any changes there either.

Thanks man...giving it a shot now!
-
When you are in your portal, you can make all of these DNS setting changes EXCEPT the MX record (First line).

Sweet...printing this out...thanks...

@garak0410 well i hope you print the one form your portal not mine!

So, this having been said, should I make a move to CloudFlare now or just update these on my current POP3 providers DNS settings (sans MX record)...? The Advanced DNS settings with my POP3 provider doesn't' allow for the SRV type for sure...

You need to make the changes where ever your DNS is currently at. If you have already signed up and tested out CloudFlare, I would personally just move everything there now.

Looks like I'll need to...current DNS (at POP3 provider) doesn't allow for SRV type...

His screenshots showing the setup of DNS entries was from his POP3 CP, not Network Solution CP. If Network Solutions isn't your DNS provider, you can't even get to the page where you would manage DNS records.
-
You don't need an SRV type for now. You only need to add the Autodiscover record for now.
-
Assuming you want to move to Cloudflare, follow the setup sets I listed earlier, then tonight before you go home, log into Network Solutions and change the IPs for your DNS providers from your POP3 to the ones provided by Cloudflare.
