Wait for Processing and Verify Storage Online
Microsoft storage upgrades often require time to process and sync across servers before reflecting in your account.
Although purchases are typically instant, server synchronization for Microsoft storage allocations can experience delays. It is highly recommended to give the system up to 48 hours to fully apply the new quota to your mailbox.
Allow 24 to 48 hours after your initial purchase for Microsoft's servers to fully process the transaction and sync the new data.
Open your web browser and sign in to your email account at www.outlook.com.
Click the gear icon (Settings) in the top right corner, navigate to 'General', and select 'Storage'.
Check your current storage allocation to verify if the new quota limit has been updated and applied.

Contact Microsoft Billing Support
If the storage does not reflect after 48 hours, manual intervention by Microsoft support is required.
