lost emails

Use Outlook.com in a desktop browser to check Recover items deleted from this folder before changing anything else, because messages absent from Deleted Items may still be recoverable there for 30 days.^1^

1. Check the hidden recoverable store

This is different from the Deleted Items folder you already inspected.

1. On a PC or Mac, sign in to Outlook.com with the MSN account.
2. Select Deleted Items in the left pane.
3. Above the message list, select Recover items deleted from this folder.
4. Look for the missing messages. Select messages carefully, then choose Restore.
5. Confirm that restored messages return to the Inbox before taking further action.

Do not select Delete, Empty folder, or anything described as permanently deleting messages. Recovery from this hidden store is unavailable through Outlook mobile apps or a mobile browser. Messages removed from Deleted Items remain recoverable for 30 days; messages in Junk Email are also automatically removed after 30 days.^1^

2. Rule out a display-only issue

If the messages are not in recoverable storage:

1. Return to Inbox.
2. Select Filter above the message list, then select All.
3. If Focused Inbox is enabled, inspect the Other tab. Moving a message from Other to Focused changes its classification; it is not necessary merely to verify that the messages exist.
4. Check Junk Email. If a legitimate message is there, select it and choose Report > Not junk.^1^

You have already established that Archive is empty and that Deleted Items contains only the 158 expected deletions, so there is no need to repeat those checks.

3. Check whether an automated action moved or removed them

On a computer, open Outlook.com Settings and review Mail > Rules. Look for an Inbox or Sweep rule that moves or deletes messages. Disable or edit an incorrect rule, but do not create new rules while investigating.^1^

Also consider whether Sweep was selected while sorting by sender. Sweep can delete all Inbox messages from a sender, retain only the latest one, or delete messages older than 10 days. That could affect substantially more messages than the few visibly selected.^2^

If a rule or Sweep action explains the disappearance, recover the messages from Deleted Items or Recover items deleted from this folder rather than attempting another bulk operation.

4. Check for access from another device or person

Review the Microsoft account’s Recent activity page for unfamiliar sign-ins, devices, or applications during the last 30 days. If anything is unfamiliar, secure the account after completing the recovery check.^1^

Also pause any phone, tablet, desktop mail program, or third-party mail application connected to the account until the investigation is complete. Do not remove the account or delete local data.

5. Escalate while recovery may still be possible

If the messages are absent from Inbox views, Junk Email, Rules destinations, and the recoverable store:

1. In Outlook.com, select Help on the menu bar.
2. Enter a missing-email query.
3. Scroll to Still need help? and select Yes.
4. Include:
   • The approximate date and time the Inbox count dropped.
   • That sorting was Sender, Z to A.
   • That selections were made with Shift in groups of 1–4.
   • The Inbox count before and after.
   • That Deleted Items contains 158 intended deletions.
   • That Archive is empty.
   • Whether recoverable items, filters, Other, Junk, rules, and recent activity produced any findings.

Ask support to investigate mailbox activity and recoverability. Avoid further cleanup or bulk moves until that review is complete.^1^
