Additional Cloud Storage with Family subscription

It seems that you are experiencing an issue when trying to purchase additional storage for your family subscription. The error message "We are sorry, the page you requested cannot be found" could be caused by several factors:

1. Eligibility of the Plan: Ensure that your subscription plan is eligible for purchasing extra storage. Not all plans may allow for additional storage purchases.
2. Region Restrictions: Sometimes, certain features or purchases may not be available in specific regions. Since you mentioned you are in Hungary, it's worth checking if there are any regional restrictions on purchasing extra storage.
3. Technical Issues: There could be a temporary issue with the Microsoft 365 service or the specific page you are trying to access. It might help to try again later or use a different browser.
4. Account Permissions: Ensure that your account has the necessary permissions to make purchases. Sometimes, account settings can restrict certain actions.

If the issue persists, I recommend contacting Microsoft support for assistance, as they can provide more specific guidance based on your account and subscription details.

by changing en-hu to hu-hu I managed to add the item to the basket and purchase extra storage.

Hello Péter Kovách, thanks for posting this in our community.

When trying to purchase additional OneDrive storage for a Microsoft 365 Family subscription, and you're redirected to a broken page that says "We are sorry, the page you requested cannot be found," this is often due to account eligibility issues or a temporary service disruption.

First, try using a different browser or device. Sometimes cached data or browser extensions can interfere with Microsoft’s purchase flow. Using Microsoft Edge or Google Chrome in Incognito Mode can help rule that out.

Also, make sure you're signed in with the primary Microsoft account that owns the Family subscription. Only the primary account holder can purchase additional storage.

You can try accessing the storage upgrade page directly via this link: https://account.microsoft.com/services/onedrive/storage If this still leads to an error, it may be due to a regional or account-specific restriction.

Kind regards,
