Understand the Difference Between Microsoft and Google Storage

Clarify how Microsoft 365 Basic storage limits apply compared to Google One storage.

Microsoft 365 Basic and Google One are two separate cloud ecosystems. Purchasing a storage subscription from Microsoft does not increase your storage capacity with Google.

Identify Microsoft 365 Benefits

A Microsoft 365 Basic subscription adds 100 GB of cloud storage. This is exclusively applied to your Microsoft services, primarily OneDrive and your Outlook.com mailbox.

Identify Google Storage Constraints

Gmail storage is managed entirely by Google and is shared across Gmail, Google Drive, and Google Photos under the Google One umbrella. Microsoft 365 plans cannot expand this Google storage quota.

Using a Gmail Address for a Microsoft Account: Even if your Microsoft account login is a '@gmail.com' email address, the Microsoft storage benefits will only apply to Microsoft services (OneDrive) and not your actual Google inbox.

Frequently Asked Questions

Can I use Microsoft 365 Basic with a Gmail address?

Yes, you can register a Microsoft account using a Gmail address. However, the 100 GB of storage provided by Microsoft 365 Basic will only apply to Microsoft's OneDrive and an associated Microsoft webmail profile. It will not increase the storage capacity of your actual Google-hosted Gmail inbox.

Why is my Outlook mailbox still full after buying Microsoft 365 Basic?

This usually happens if OneDrive files are consuming your entire Microsoft storage quota, or if the subscription was purchased on a different Microsoft account. Check your storage breakdown at account.microsoft.com and clear out large OneDrive files or empty your Outlook 'Deleted Items' folder.

How do I check my current Gmail storage limit?

You can check your Gmail storage by scrolling to the very bottom of your inbox page on a desktop browser, where you will see a storage progress bar. Alternatively, you can visit one.google.com/storage to see a detailed breakdown of your usage across Google Drive, Gmail, and Google Photos.
