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.

Right...going to do all but 3 today/this week...I think you and @Dashrender have both demystified most of this for me...E-Mail is crucial at this place...and DNS is not my strong suit but improving...

I would want to move my DNS records at night or some other time when no one else is working. And you'll need to prep everyone that email is going down.

Yes...was planning on that this Friday evening...

Moving right along...continuing my setup on the Office 365 portal and verifying my domain ownership, it is asking me to create a txt record. Since my POP3 provider handles my advanced DNS, I will do it there.
Assuming the TXT entry is benign at this point, correct?

Correct.
But Add the text record in both places as you will be dumping that DNS provider.

OK...adding the TXT entry now...

TXT entries went fine...imported my users but "Plain Jane" (just email and name) as our HR VP didn't want any other info in the shared contacts. Been busy with other things today so not much more progress made.
So really, all that is left now is how/when I plan to update Outlook, mobile users and the time for the DNS/MS entry moves...

Quick Update - I am doing my one hour "training" at 11PM today...much of those were answered in this thread!

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.

Especially as messed up as this config seems to be.
- Move everything to Network Solutions.
- Get the migration handled.
- Move DNS to another provider.

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?
