How to Migrate Data Between Multiple Microsoft 365 Accounts

When you change jobs, rebrand your business, or merge personal and professional workspaces, figuring out migrating Data Between Multiple Microsoft 365 Accounts becomes a critical task. Moving emails, contacts, and terabytes of cloud files manually can lead to corrupted data or lost correspondence if not handled correctly. this guide explains the native workflows to securely transfer your Outlook data and OneDrive files from one account to another without relying on expensive third-party migration tools.

Transferring Emails and Contacts Using Outlook PST Export

The most reliable native method for transferring mailbox data requires the desktop version of Microsoft Outlook. Web-based forwarding does not retain folder structures or historical calendar events.

To begin, open the Outlook desktop application while logged into your source account. Click File in the top left corner, navigate to Open & Export, and select Import/Export to launch the wizard. Select Export to a file, click Next, and choose Outlook Data File (.pst). You must select the top-level mailbox folder, which is typically labeled with your email address, and ensure the Include subfolders checkbox is actively ticked. Save this .pst file to your local desktop so it is easily accessible.

Next, add your destination account to the same Outlook desktop client. Go back to File and click Add Account, entering the credentials for the new profile. Once the new inbox populates in your left sidebar, reopen the Import/Export wizard via File > Open & Export. This time, select Import from another program or file. Choose the .pst file you just saved to your desktop. In the final prompt, select Import items into the same folder in and choose your destination email address from the dropdown menu.

To verify the process, click the Send/Receive tab and click Update Folder. You will see the status bar at the bottom of the screen syncing the imported data up to the new cloud server. Executing this PST method is a foundational step while working on migrating Data Between Multiple Microsoft 365 Accounts safely.

Shifting OneDrive Files Across Accounts Locally

Downloading large directories directly from the OneDrive web browser interface often results in corrupted zip files or server timeout errors. Using the Windows File Explorer sync method is significantly more stable for bulk file transfers.

First, ensure the OneDrive desktop client is running. Click the OneDrive cloud icon in your system tray, click the Gear icon (Settings), navigate to the Account tab, and click Add an account. Log in with the credentials of your destination Microsoft 365 account. Once configured, open Windows File Explorer. You will now see two distinct OneDrive folders in the left navigation pane—one for the source account and one for the destination account.

Open the source OneDrive folder. Press Ctrl + A to select all your files and folders, then press Ctrl + C to copy them. Navigate to your new destination OneDrive folder and press Ctrl + V to paste the items. Do not use the cut command, as keeping the original files intact serves as a backup during the upload process.

Monitor the sync status icons next to your pasted files. A blue circular arrow indicates the file is currently syncing to the new tenant, while a solid green checkmark confirms the file is successfully uploaded and secured in the new cloud. Syncing locally prevents browser timeout errors, making this the preferred strategy for migrating Data Between Multiple Microsoft 365 Accounts.

Managing Documents with WPS Office Post-Migration

Transitioning between Microsoft subscriptions often involves temporary license lapses or a deliberate decision to downgrade a costly plan. While WPS Office cannot natively execute server-to-server cloud migrations or alter Microsoft tenant permissions, it serves as an excellent offline bridge for your actual document workflows.

If you cancel the source Microsoft 365 subscription before the destination account is fully configured, your local Office applications may enter restricted mode, preventing you from editing your Word, Excel, and PowerPoint files. By installing WPS Office, you can instantly open, edit, and save all your downloaded .docx, .xlsx, and .pptx files directly from your local drive without encountering license activation pop-ups.

WPS Office provides a unified, tabbed interface to manage your spreadsheets, presentations, and documents locally. Once you are comfortable with migrating Data Between Multiple Microsoft 365 Accounts, you might realize you no longer need multiple another paid subscription. WPS Office offers robust PDF editing tools, built-in AI writing assistance, and seamless format compatibility, allowing you to maintain full productivity on your newly transferred local files while avoiding dual subscription fees.

FAQs About Migrating Data Between Multiple Microsoft 365 Accounts

Can I migrate my data entirely through the web browser?

No, transferring massive amounts of data exclusively via the web interface is highly prone to timeout errors and connection drops. Browsers compress large OneDrive downloads into zip files that often fail to compile. Using the desktop Outlook client for emails and Windows File Explorer for OneDrive ensures a stable, trackable transfer.

Will exporting my Outlook data delete it from the original account?

Exporting to a .pst file creates a copy of your mailbox data at that specific moment; it does not remove or alter the original emails, calendar events, or contacts from the source Microsoft 365 server. Your data remains completely intact on the old account until the system administrator explicitly deletes the user profile.

How do I handle OneNote notebooks during this transfer?

OneNote notebooks do not migrate smoothly through the standard OneDrive copy-paste method because they are synced via unique web shortcuts rather than standard file formats. You must open the specific notebook in the OneNote desktop application, click File > Export > Notebook > OneNote Package (*.onpkg), save it locally, and then unpack it into your destination account's OneDrive directory.

Do shared permissions transfer when I move my OneDrive files?

No. When you copy files from one Microsoft 365 account to another, you are creating entirely new file instances in the destination tenant. Any previous sharing links, password protections, or collaborative editing permissions tied to the old account will break permanently. You must manually generate new sharing links from the destination account once the sync is complete.
