cannot get messages in outlook classic

Because the Inbox is empty on Outlook.com, classic Outlook, and the iPhone, check the Outlook.com service status first and then troubleshoot the online mailbox rather than reinstalling or reconfiguring either app.

1. Check the current Outlook.com service status

A widespread Outlook/Microsoft 365 disruption began on November 12, 2026 and affected inbox loading and mail delivery. Open the Microsoft service-health page and check whether Outlook is still reporting an active incident for your region/account ^1^.

• Active incident: Avoid deleting or re-adding the Outlook account. Wait for Microsoft to mark the incident resolved, then sign out of Outlook.com, sign back in, and send a new test message from another account.
• No active incident: Continue with the account checks below.

2. Check whether storage is full

In Outlook.com:

1. Select Settings (gear icon).
2. Search Settings for Storage, then open the storage page.
3. Check both mailbox and Microsoft cloud-storage usage.

If either quota is full, Outlook.com cannot receive new messages. Messages sent while storage was full are returned to the sender and are not delivered later automatically; after freeing space, ask senders to resend them ^2^.

3. Find and recover messages already in the mailbox

On a computer at Outlook.com:

1. Above the message list, select Filter > All.
2. Check Other, Junk Email, Archive, and Deleted Items.
3. In Deleted Items, select Recover items deleted from this folder.
4. Select the missing messages and choose Restore.

Items removed from Deleted Items are recoverable for 30 days. This recovery view must be accessed from a PC or Mac, not Outlook for iPhone or a mobile browser ^3^.

Also search for a known sender or subject across All folders. Outlook.com documents filters, Focused Inbox, rules, Archive, Junk, and Deleted Items as common reasons for an apparently empty Inbox ^4^.

4. Stop rules or forwarding from removing new mail

Using Outlook.com on the computer:

1. Open Settings > Mail > Rules.
2. Disable or delete any rule that moves or deletes incoming messages.
3. Open Settings > Mail > Forwarding.
4. Turn forwarding off if it was not intentionally configured.
5. Send a new test message from a different email account.

If an unfamiliar rule or forwarding address appears, also review the Microsoft account’s Recent activity page for unfamiliar sign-ins and follow the security actions offered there ^4^.

5. If POP or IMAP is enabled

This branch applies only if Outlook.com settings show POP or IMAP access enabled:

1. Open Settings > Mail > Forwarding and IMAP.
2. Disable POP and IMAP.
3. Save the change.
4. Send another new test message from a separate account.

An older computer, phone, or mail application using POP can download messages and remove them from the server. Microsoft also recommends disabling active POP/IMAP while testing receipt problems ^5^.

Disabling POP/IMAP can prevent further interference, but it does not restore messages already removed. Recover those through Deleted Items/Recoverable Items, or request a mailbox investigation.

6. Escalate to Outlook.com support

If Outlook.com remains empty after the service incident is resolved, storage is below quota, and a newly sent test message does not arrive:

1. In Outlook.com, select Help.
2. Enter Inbox empty and not receiving email on any device.
3. Scroll to Still need help? and select Yes.
4. Include:
   • The approximate date and time mail stopped appearing.
   • Confirmation that Outlook.com, classic Outlook, and iPhone all show the same empty mailbox.
   • The sender and timestamp of a recent test message.
   • Whether Deleted Items recovery, rules, forwarding, POP/IMAP, and storage were checked.

Outlook.com support can investigate server-side mailbox data; reinstalling classic Outlook or the iPhone app cannot restore messages that are also absent from Outlook.com ^6^.
