      Very good info guys and as Scott says, good "knowledge base" info.

      Let me digress for a second...because I may end up needing help here...

      Our domain name is registered with Network Solutions and is currently pointed to our POP3 provider who also hosts our webpage. The webpage actually has a pointer to our WIX page, which we have set in the POP3 providers control panel. So when the POP3 provider shuts down all of our services, do I simply point the domain to the Wix page or will this be a little more complicated with the MX records and such? Thanks...

      This old post tells me that your DNS provider is really your POP3 provider, not Network Solutions. Which is it? If Network Solutions is pointing to your POP3, then you should change that to either Network Solutions or another provider that you have greater control of first (Scott suggests CacheCade - which is free for a low end account). This will take upwards of 3 days to propagate throughout the internet (but could be far less).

      Once you move your DNS, then you can start on confirming the ownership with MS for O365.

        Sorry, I guess things get lose in the thread or I am not explaining it clearly. Here is a repost from above:

        Our DNS is at Network Solutions. It lists all 4 of our owned domain names (though we just use the one for everything.) All 4 domain names point back to our current POP3/IMAP provider and website host. At the POP3/website provider, it has a ton of entries that cover Name, TTL, Class, Type, Record. When we leave the POP3 email provider, all of that will go away.

        Under the name heading, we have things like:

        domainname.com
        localhost.domainname.com
        mail.domainname.com
        www.domainname.com
        ftp.domainname.com
        cpanel.domainname.com
        whm.domainname.com
        webmail.domainname.com
        webdisk.domainname.com
        autoconfig.domainname.com
        autodiscover.domainname.com

        Most of these are configured with 14400 TTL, are with the CLASS IN, and TYPE A. The main.domainname and webmail.domainname are CNAME's. Most records are to a specified IP address with the CNAME's going to the domainname.com

        So, network solutions is our registrar...however, with our POP3 provider, in their control panel, we have the options for setting the Name, TTL, Class, Type, Record.

        I pray I am explaining what you were asking...LOL.

        Basically, I want nothing to do with the POP3 provider come the day I update the MX records and go live with 0365.

          WoW.. I love the 'value' they put on those services - what a load!

          Except for this "hour training" I get, yeah, no real value...and they couldn't schedule it until Wednesday either and I wanted to get going on this TODAY... 😞

            garak, can you post a screenshot from Network solutions, you can blackout the exact domain names and IP addresses.

            That will give me a good start to see if we are on the same page.

              Here are my current options on Network Solutions, the domain registrar...

              dns01.jpg

              All of the pointers point to our POP3/Website provider.

              And these are the advanced DNS options on the POP3 provider site:

                You need to start by moving your DNS to another provider. You can simply move them back to network solution if you like, Click on the Manage buttons I've circled below:
                1.JPG

                When I click on Manage on one of my Network Solutions accounts I see the following:
                2.JPG

                Now I click on Change where my Domain Points and I get this

                3.JPG

                If I pick what I have labeled as 1:
                4.JPG
                Only choose this if you have already setup another provider to be your DNS provider on the web (such as CacheCade) Otherwise choose option 2

                For option 2:
                5.JPG

                You will now have Network Solutions provide your DNS for you. Once you accept this page, you'll need to create all of the records you saw on your POP3 control panel.

                  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.

                      Excellent...thanks...

                      Back to exchange online...what can I really accomplish today/this week before I do all of this? Looking back at your suggestions,

                      @Dashrender said:

                      This would seem to be a pretty good way to have the users experience as little change as possible.
                      Here are some steps:

                      1. create all users on Exchange
                        a) log into the web interface for one user and make sure you can send an email from that account and it appears to be coming from your domain, if not, you need to fix this first
                      2. create DNS records for autodiscover as directed by MS (DO NOT CHANGE THE MX RECORD, yet)
                      3. 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
                      4. Now you can change your MX record to O365's settings. You'll start receiving your new mail directly in O365
                      5. after at least double your MX records TTL (if set to 24 hours, wait 48 hours) you can visit the client workstations and
                        a) remove the POP3 account from the Outlook profile
                        b) disconnect the PST file
                        c) import the contents of the PST to O365 (depending on the size and how fast your internet connection is, this might take a while)

                      I can go up to step 3 today, correct? Was going to start with my ID...

                        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.

                                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.

                                      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...

                                          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.
