Question details

The user needs to consolidate two different Microsoft 365 subscriptions (one direct and one purchased via GoDaddy) to support multiple business email accounts and securely migrate mailbox and OneDrive data.

How to Combine Microsoft 365 Subscriptions and Business Email Accounts

Product: Microsoft 365 / Outlook
Device & OS: not provided
Scenario: A business user has an expiring Microsoft 365 subscription and a new GoDaddy-managed subscription, and wants to consolidate inboxes and data before the old subscription expires.
Observed behavior: The user is seeking guidance on combining multiple email accounts in Outlook, migrating large mailboxes, and transferring OneDrive data to an external drive or a new tenant.

Before you start

Do not cancel your expiring Microsoft 365 subscription until you have completely backed up or migrated all your Outlook mailbox data and OneDrive files to the new account.

Solution 1Recommended

Manually Backup and Migrate Outlook and OneDrive Data

Use Outlook's built-in export tools and local storage to safely move your emails and files to the new Microsoft 365 account.

Since Microsoft 365 subscriptions, user licenses, and email accounts are separate components, the safest way for an end-user to migrate data between two distinct tenants (such as a direct Microsoft tenant and a GoDaddy tenant) is by manually exporting the data.

Export your old mailbox to a PST file

Open the Outlook desktop app linked to your old account. Go to File > Open & Export > Import/Export. Select 'Export to a file', choose 'Outlook Data File (.pst)', select your entire mailbox, and save the file to your computer.

Backup your OneDrive data

If you have a large amount of OneDrive data, connect an external hard drive. Open your old OneDrive folder in File Explorer and copy all files and folders to the external drive to secure your data.

Import data to the new account

Add your new GoDaddy Microsoft 365 email account to Outlook. Once configured, go to File > Open & Export > Import/Export. Select 'Import from another program or file', choose the PST file you created, and import the items into your new mailbox.

Outlook Multiple Accounts: The Outlook desktop application can comfortably host multiple valid email accounts simultaneously, allowing you to manage both inboxes side-by-side during the transition period.

Solution 2

Coordinate Migration with GoDaddy Support or IT Administrator

Work with the Microsoft 365 administrator or GoDaddy support to perform a server-side domain and mailbox migration.

Frequently Asked Questions

Will canceling my old Microsoft 365 subscription affect my old mailbox?

Yes. Depending on the tenant's specific configuration and retention settings, your old mailbox may become entirely inaccessible, and the data could be permanently deleted shortly after cancellation. Always back up your data before canceling.

Can the Outlook app support multiple email accounts from different subscriptions?

Absolutely. The Outlook desktop application is designed to contain and manage multiple valid email accounts simultaneously, even if those accounts are hosted on entirely different Microsoft 365 subscriptions.

How do I migrate a large amount of OneDrive data if my computer lacks storage?

For large amounts of data, it is recommended to purchase or use an external hard drive. You can download the files from your old OneDrive directly to the external drive, and then upload them to your new Microsoft 365 OneDrive account from the drive.

Are a Microsoft 365 subscription and an email account the same thing?

No, they are separate concepts. A subscription provides the underlying licenses and services (like Word, Excel, and Exchange online), while an email account is a user profile assigned one of those licenses. Staff members within a business can technically remain on different subscriptions if necessary.
