Outlook Storage Limit Not Updating After Upgrade

Hi Micaela Sutton,

This usually means the account’s storage entitlement hasn’t fully refreshed yet, the added storage hasn’t finished provisioning, or the purchase was made under a different Microsoft account than the affected Outlook.com address.

For New Outlook for Windows, please try the steps below in this order:

Sign in to Outlook.com on the web and check Settings → Storage / Manage storage there first. This helps confirm whether the account itself is still over quota, or if only the app hasn’t updated yet.

1. Go to Microsoft account > Payment & billing > Order history and confirm that both storage purchases appear under the same Microsoft account as the blocked email address. This verifies that the extra storage was applied to the correct account.
2. If you see a charge on your bank/card statement but do not see the subscription listed in Order history under the correct account, that usually indicates a provisioning issue. This can’t be corrected from the user side. Microsoft Support would need to review the charge, issue a refund if needed, or force the storage entitlement onto the account.

If the purchase was very recent, allow some time for the storage upgrade to appear on the account.

1. If the web account already shows available space, sign out of New Outlook and sign back in. If needed, remove and re‑add the Outlook.com account in the app. (Note: Before removing an account, make sure there’s no unsynced local‑only data.)

If it has been more than a day and the purchases are on the correct account but Outlook still reports that you’re over the limit, contacting Microsoft Support for an account and billing review is the next step, as duplicate charges or missing storage entitlements require account‑side investigation.

If possible, please also share the exact last line of the storage warning (in quotes). That often helps confirm whether the block is coming from mailbox quota, Microsoft cloud storage, or an account sync issue.

Please let me know if this proves useful to you, or if you would like assistance in navigating Microsoft's Support Channel.

I'm looking forward to your reply.

The mailbox and cloud storage quotas have not actually updated yet, so Outlook.com still treats the account as over its limit even though items were deleted and storage was purchased.

Key points from the current behavior of Microsoft unified storage:

1. When Microsoft cloud storage is full:
   • Sending and receiving email in Outlook.com is blocked, even if the email storage itself is not full.
   • Messages sent to the account while storage is full are bounced back to the sender and are unrecoverable.
   • OneDrive becomes read‑only for new uploads/edits.
2. When email storage is full:
   • Sending and receiving email in Outlook.com is blocked.
   • Messages sent during this period are returned to the sender and must be resent after the quota issue is fixed.
3. Getting back under the storage quota:
   • For free accounts: either buy a subscription to increase limits or free up storage using the storage management tools.
   • For Microsoft 365 consumer subscribers: mailbox size is capped at 100 GB; if that limit is reached, space must be freed. For more than 100 GB, only Enterprise plans provide higher limits.
4. If storage or quota has not updated after changes:
   • Check the current storage directly in OneDrive and in Outlook.com under Email storage to confirm the live quota and usage.
   • On mobile, force a refresh by fully closing and reopening the Outlook app, then in Settings → Account → Storage, tap the subscription type (Free plan or Premium) to refresh the storage status.
   • If the account was locked due to being over quota, it can take up to 2 hours after purchasing additional storage for the new quota to show. If the quota still has not updated after 4 hours, direct contact with Microsoft support is required.

Given that:

• Email and OneDrive content have already been deleted, and
• Additional storage has already been purchased (twice), and
• Outlook still reports being over the limit,

the next step is to:

1. Confirm the current storage status using the official storage views (OneDrive website and Outlook.com → Email storage) to verify that usage is now under the quota.
2. If more than 4 hours have passed since the last storage purchase and the quota still shows as exceeded or the account remains blocked, contact Microsoft support using the Outlook.com or Microsoft account support channels so they can correct the quota state on the backend and review the duplicate charges.

During the blocked period, any emails sent to this primary address are bounced and cannot be recovered, so senders will need to resend messages after the quota issue is fixed.
