This related Reddit discussion indicates that it's possible and working at the time. It involves pretending to go to GoDaddy, and then capturing key values from the outlink for manual DNS updating.
https://www.reddit.com/r/Office365/comments/ft15pk/use_personalized_domain_with_outlook_and_office/
Go to outlook, the premium settings and choose the option to "get started" with a personalized domain.
Click the option to buy a new domain with GoDaddy, and a new window opens
Copy the URL of the new window that opens, it should look like this: https://domainconnect.godaddy.com/v2/domainTemplates/providers/outlook.com/services/personalizedoutlookemail/apply?mxRecordValue=XXXXXXXXX&state=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
The part that you need is "mxRecordValue=XXXXXXXXX"
The XXXXXXXXX is the unique ID for verification used in DNS
Go to your own domain DNS settings and add the following settings replacing XXXXXXXXX with your ID found in step 3.
The dot on the end of the external domains is not a typo!
Name TTL Type Value Priority @ 1 hour MX XXXXXXXXX.pamx1.hotmail.com. 0 @ 1 hour TXT v=spf1 | include:outlook.com -all autodiscover 1 hour CNAME autodiscover.outlook.com. _dmarc 1 hour TXT v=DMARC1; p=none; _domainconnect 1 hour CNAME _domainconnect.gd.domaincontrol.com. _outlook 1 hour TXT XXXXXXXXX
Return to the premium settings in outlook to set your custom domain.
Choose the option "I already have a domain"
Enter the domain you just configured
You have to click to login to GoDaddy, do this, but just exit the page it goes to.
Congratulations it should now say you connected the domain with GoDaddy!
I have been with GoDaddy since 2007 with ~26 domains and 80 email addresses. They recently decided to stop doing POP & IMAP email with the CSR(s) telling me that 'your email is going to not work any longer because the industry has stopped accepting those old standards. You have to move to our Office 365 email or your mail will not work.' That BS wording rankled me to no end.
Given the difficulty of moving all of those domains and email, I hunkered down and started the pain of transferring the most entrenched domains to Office 365. Nothing but problems. The most recent problem is that I can not create SharedMailboxes in the admin.exchange.microsoft.com interface as they will not work on my client's Macs. GoDaddy's solution to this is to have my clients all move to an Outlook email client instead of their Apple Mail. Since that was not going to happen, they next suggested that I create the SharedMailbox from a standard email client license. That way the Mac users could log in to the account and just use them like normal email accounts instead of the SharedMailox feature that I was sold as being worth the transfer to the Office 365 email. (Yet another purchase of another email license.)
Another item that may help other Office 365 users was an error when a Mac client attempted to add an Office 365 email account to their Apple Mail program and got an error of 'You are already logged into that account.' as if the email address already existed in their Apple Mail. GoDaddy of course insisted that the user did already have that account entered and just did not see it. Then it was blamed on the 3rd party Apple Mail client and that the user should call Apple.
With all of that non-help to fix the Office 365 Exchange problem, I finally found a MS program 'Microsoft_Office_Reset_v1.9.1' that I ran which removed all of the Office history and then the user could add the Exchange account as needed.
I have two domains and paid Email services programs with GoDaddy over the past 12 years! Last week, I suddenly noticed that I could not access my emails via outlook. Then I re-installed outlook and got noticed that " The license provided by your work or school does not enable access to Outlook for Windows. Please access your email through Outlook on the web instead."
And then by chatting with GoDaddy Online support, I was told to upgrade with $217 for my rest three years contract would be the only options for me to access my email using outlook! I have the 365 email plus signed with GoDaddy years ago!
If I would have offered this type of service, I would not renew my services with GoDaddy two years ago for a 5 yrs max term. Not sure, if anyone else noticed this type of changes to their email services with GoDaddy?
And what would be an alternate option to access email using outlook?
Thank you for any suggestion!
I bought a godaddy domain last year for my new business. A year later i realized that i do not enjoy outlook nearly as much as Google. I now want to take this domain and transfer it to Gmail. In that process i plan to delete my go daddy account. However, i cannot find a simple and quick method to transfer all my data and get that custom domain to google. Online i see a lot of information on IMAP however, that all confuses me. Can someone help explain on how i can go from godaddy/outlook to gmail? WIthout loosing any data and completely cutting ties with godaddy?
