Not Receiving Emails

Question

Not receiving emails in my account. I usually receive 200+ emails a day, today I haven't received any

Answer 1

Check Outlook on the web and Microsoft’s service-health page first to determine whether today’s interruption is service-wide, mailbox-level, or limited to the iPhone app. ^1^

1. Test delivery outside the iPhone

1. Sign in to Outlook on the web from a browser.
2. Send your address a new message from another email account.
3. Check Inbox, Other, Junk Email, Deleted Items, and Archive.
4. Check Microsoft’s service-health page for an active Outlook incident.

Then follow the matching result:

• Missing on the web and iPhone: Continue with the mailbox checks below. If service health reports an incident, wait for Microsoft to mark it resolved before changing the phone configuration.
• Present on the web but missing on the iPhone: The mailbox is receiving mail; repair the iPhone synchronization using section 3.

2. If mail is also missing on the web

In Outlook on the web:

1. Open Settings → Mail → Storage and check whether the mailbox or Microsoft cloud storage is full. A full Microsoft cloud storage allocation prevents sending and receiving; messages sent while it was full are returned to the sender and cannot later be recovered. ^2^
2. Open Settings → Mail → Rules and disable any unexpected rule that deletes or moves incoming mail.
3. Open Settings → Mail → Forwarding and verify that mail is not being redirected unexpectedly.
4. Clear filters, then select Filter → Sort → Date.
5. Review Other and Junk Email again.

If this is a work or school Microsoft 365 account and no incident is listed, contact the organization’s Microsoft 365 administrator. If it is an Outlook.com, Hotmail, Live, or MSN account, use Help in Outlook.com and select Still need help? if its troubleshooter does not resolve delivery. ^2^

3. If messages appear on the web but not on the iPhone

Outlook for iOS app

1. Open Outlook → profile icon → Settings → Accounts.
2. Select the affected account.
3. Tap Reset Account, then check whether current messages synchronize.
4. If that fails, return to the account settings and select Delete Account → Delete From This Device.
5. Add the account again and sign in.

Microsoft documents reset first, followed by deleting and re-adding the account if synchronization still fails. ^3^

Apple’s built-in Mail app

If Apple Mail shows Please enter the password, Account not authenticated, or Cannot Get Mail – The connection to the server failed:

1. Open iPhone Settings → Apps → Mail → Mail Accounts. On some iOS versions, the path is Settings → Mail → Accounts.
2. Select the Outlook or Hotmail account.
3. Open Account Settings or the Password field.
4. Enter the current password and tap Done.
5. Reopen Mail and confirm that the test message appears.

These specific messages indicate an iOS Mail authentication issue requiring another sign-in. ^4^

If reauthentication fails but webmail works, remove and re-add the account using Outlook.com for a personal Microsoft account or Exchange for a Microsoft 365/Exchange account. ^3^
