Fix Microsoft Storage Capacity Not Showing in Outlook
Question details
The user recently purchased a 1 TB Microsoft storage subscription, but Outlook continues to show a 5 GB limit and displays a mailbox full error.
- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Upgrading Microsoft storage subscription to resolve a full Outlook mailbox.
- Observed behavior
- Outlook fails to recognize the new 1 TB storage capacity, continuing to block new emails by reporting a 5 GB limit and a full mailbox status.
Ensure that you are logged into Outlook with the exact same Microsoft account that was used to purchase the new 1 TB storage subscription.
Allow 24 to 48 Hours for Storage Synchronization
Microsoft subscription changes require time to fully sync across backend services. Wait for the system to process your recent purchase.
When you purchase additional Microsoft storage or upgrade your Microsoft 365 subscription, the new capacity does not immediately apply to all linked applications. The servers need time to process the payment and synchronize the new quota to your Outlook mailbox.
Log in to your Microsoft account online and navigate to the Order History section to confirm the 1 TB storage subscription is marked as 'Completed'.
Allow up to 24 to 48 hours for the new storage limit to automatically reflect in your Outlook account.
After the waiting period, completely close and reopen your Outlook desktop app, or refresh the Outlook web page to prompt a status check of your mailbox capacity.
Contact Microsoft Online Support
If your Outlook storage capacity hasn't updated after 48 hours, you will need to contact Microsoft Support to manually verify and sync your subscription.
Try WPS Office for a Seamless Productivity Experience
While waiting for your Microsoft storage issues to be resolved, consider using WPS Office. It is a highly compatible, free, and lightweight alternative to Microsoft Office, offering powerful word processing, spreadsheets, and presentation tools without expensive subscription fees.

- 2. Download the installer: Click the 'Free Download' button to save the installation file to your computer.
- 3. Install and launch: Run the downloaded file and follow the simple on-screen instructions to start using your new office suite.
Frequently Asked Questions
Why does Outlook still say my mailbox is full immediately after I bought more storage?
Microsoft's backend servers can take between 24 and 48 hours to synchronize newly purchased storage quotas across all associated applications, including your Outlook email and OneDrive.
How can I check my current Outlook storage limit?
In Outlook on the web, click the Settings (gear) icon, navigate to 'General', and select 'Storage'. Here you can view your current mailbox usage and your total available capacity.
Will I lose emails sent to me while my mailbox is full?
Emails sent to you while your mailbox is full will typically bounce back to the sender with a non-delivery report. You will need to ask senders to resend their emails once your new storage capacity is active.
Can I speed up the storage synchronization process?
No, the synchronization process is handled automatically on Microsoft's servers and cannot be manually accelerated. However, logging out of your account and logging back in across all your devices can occasionally help refresh your local application status.
