thank you Diane. Yes I do have a 365 Personal subsription on ******@outlook.com

I added a my email as a test and it returns an error of "You can't add a work or school email address as an alias to a personal Microsoft account. Please try another."

I added a made up name to see if this was just my personalised domain it wouldn't accept. It took the made up name, and didn't take my personal one. So yes I see what to do, and thank you for making that clear.

However, this is a live service and I cannot lose email. So preumably it will take time to delete the GoDaddy instance of 365, and in the meantime, what do I do to minimise loss of email? this is a live email service which has been used for decades.

thank you

r/Office365 on Reddit: Migrating from Godaddy M365 to Microsoft 365
July 20, 2023 -

I have a customer who has about 50 email accounts, or about 1.2Tb of data on the GoDaddy Microsoft 365 platform. There are several limitations we are running into and the customer would like to migrate to a true Microsoft 365 Platform.

I have done a M365 Tenant to Tenant migration before and it was not a pleasant experience. Microsoft provided 0 support, and actually told me that it was impossible to do, so I basically had to perform complete backups of all email accounts, then re-upload them.

I do have some concerns about the migration because I basically have to release the tenant name back to public, then re-acquire it after 24 hours, according to what I have seen. The customer has someone (believed to be their previous IT person who may or may not still be in contact with employees at the company) actively trying to sabotage them on a very frequent basis. I am concerned this person may try to acquire the tenant's name during the 24 hours and get it before I am able to.

Beyond that, I am very interested to know what tools you have successfully, or unsuccessfully, used for this process. While I have a fairly fast 500Mbps internet connection, it still seems to take several days to download the entire data set. I would like something I can do a trial run with, then something I can run differential backups with right up until the last minute.

I would also like to set up something to cache all the emails while the system is down. I am thinking something along the lines of a Linux mail server, or maybe a 30-day trial of a mail security program that has that functionality.

How to Migrate GoDaddy Email to Office 365/Microsoft 365?
July 28, 2025 - Use the mailbox credentials to facilitate the migration from GoDaddy to Office 365. Your CSV file is now ready with the requisite information. In this step, it is assumed that you do NOT have a purchased domain that has been configured to work with your Microsoft Office 365, nor do you have a tenancy for Office 365. The created email accounts and the user profiles are now in the Office 365 system.

Under Primary email address and username, select the staging domain from the list. The staging domain will contain “onmicrosoft.” · Save a copy of the username and staging domain, and then select Done. Under Aliases, next to your original username, select More actions. Select Delete alias. Repeat this for any additional aliases using the primary domain. Select Save changes. Repeat these steps for every user on the domain that is migrating from Microsoft, and then remove the domain from your Microsoft account.

Hi, I'm Diane and I'm happy to help you today.

You need to have a subscription =- if you only need one address in the domain, a Microsoft 365 personal subscription is fine. consumer custom domains don't have an admin portal - they use the personal email page in Settings > Premium.

If you have a Microsoft 365 mailbox from GoDaddy, you need to cancel that - then when it is removed from the Microsoft servers, you can add the domain in Outlook.com's Settings (gear icon) > View all Outlook settings > Premium > personalized email and add the alias. (The alias cannot exist on the account in account.microsoft.com - you'll create it on this page.)

Microsoft article on adding a custom domain: https://support.microsoft.com/office/get-a-personalized-email-address-in-microsoft-365-75416a58-b225-4c02-8c07-8979403b427b

As long as you keep the subscription, you can use the address after November. But it needs to be set up before then.

Let us know how it goes, we're here to help you further if needed.

Hi @eg1995 ,

To migrate from godaddy to o365, you could follow these steps:

1.Purchase an Office 365 plan from Microsoft directly.

2.Create mailboxes on the new subscription using the default onmicrosoft.com temporarily.

3.Perform an IMAP migration to move the mailbox data.

4.After the migration, remove your custom domain from your Office 365 plan in GoDaddy.

5.Cancel your Office 365 subscription in GoDaddy.

If you are not clear about above actions in GoDaddy, you may need to consult GoDaddy support for the detailed steps.

6.Add and verify your domain in Office 365.

7.Change the user mailboxes from onmicrosoft.com to the verified domain.

I have extensive experience with tenant-to-tenant migration projects. In my most recent project, I managed the migration of workloads from GoDaddy (Office 365) to standard Office 365.

   The primary difference between GoDaddy Office 365 and standard Office 365 is the login page, which is customized by GoDaddy. Apart from that, the migration process is essentially an Office 365 to Office 365 migration, which is straightforward when using third-party migration tools like AvePoint and BitTitan (my preferred tool). 

These tools are particularly effective for migrating diverse workloads, including Teams chats, Teams Channels, SharePoint sites, OneDrive, and Exchange mailboxes. It's important to note that IMAP migrations only transfer emails and do not include calendars, signatures, contacts, and other data, making third-party migration tools necessary for comprehensive migrations.
