not receiving emails in Outlook 365 in a week.

Question

Somehow I am not receiving emails on my desktop outlook as well as the web app too.

Answer 1

Hi, I'm John! I will help you with this.

To help narrow down the issue:

1. Are you using Outlook on the web, Outlook for Windows/Mac, or the Outlook mobile app?
2. Is this happening on one device or on all your devices?
3. Have you checked if Focused Inbox is turned on and if your emails might be going to the Other tab instead of the main Inbox?

In the meantime, I recommend checking out this Microsoft support article:

• "Can't send or receive email in Outlook.com" https://support.microsoft.com/office/can-t-send-or-receive-email-in-outlook-com-d39e3341-8d79-4bf1-b3c7-ded602233642 Please scroll down and take a look at the sections titled "Can’t receive mail in Outlook.com". It walks you through some helpful steps that usually resolve this kind of issue.
• Check your mailbox settings to confirm nothing is filtering or blocking those emails.
• Make sure your Focused Inbox is turned off, so all messages show in one place. https://support.microsoft.com/office/focused-inbox-for-outlook-f445ad7f-02f4-4294-a82e-71d8964e3978
• Try adding their email addresses to your Safe Senders list to make sure Outlook doesn’t block or redirect them. https://support.microsoft.com/office/add-recipients-to-the-safe-senders-list-in-outlook-be1baea0-beab-4a30-b968-9004332336ce

Check any Outlook rules:

• In https://outlook.live.com/mail go to Settings > View all Outlook settings > Mail > Rules and Mail > Forwarding to make sure no one has set up rules to forward or delete your messages.

Follow these checks and fixes in order:

1. Confirm internet connectivity
   • Open a browser and go to http://www.microsoft.com or http://www.bing.com.
   • If these do not load, fix the network first using the steps in Fix network connection issues in Windows.
2. Check Outlook is online and syncing
   • In Outlook for Windows, go to the View tab and select Sync to force a manual sync. Watch the status bar for sync progress.
   • If using Outlook for Mac, make sure Outlook > Work Offline is not checked.
3. Verify mailbox/storage is not full
   • If Microsoft cloud storage is full, sending and receiving email stops.
   • Check mailbox storage using the storage link described in the article and free space if needed.
4. Make sure the account password is correct
   • If the password was changed recently on the email provider’s website, update it in Outlook:
     1. Select the icon next to the email account name in new Outlook.
     2. When prompted, select Continue and sign in with the current password.
   • If Outlook asks for an “app password,” generate it on the email provider’s site and use that in Outlook.
5. Check for rules or filters diverting mail
   • In Outlook desktop, review rules that might move or delete new mail (for example, diverting to RSS or another folder).
   • In Outlook.com/Outlook on the web, check Settings > Mail > Rules for any rules that move or delete incoming messages.
6. Check blocked senders and junk
   • In Outlook.com/Outlook on the web:
     1. Sign in.
     2. Go to Settings > Options/Mail.
     3. Open Blocked senders or Block and allow.
     4. Remove any addresses or domains that should be allowed.
   • In Outlook 2016/Classic Outlook:
     1. Home tab > Junk > Junk Email Options.
     2. Blocked Senders tab and remove any legitimate senders.
7. Confirm messages are not filtered by the view
   • Ensure the Inbox view is not filtered to an old date range or custom filter (for example, “Favorites inbox set to Tuesday”). Reset the view or switch to the main Inbox folder and show All messages.
8. Use Outlook troubleshooters (Classic Outlook)
   • If using Classic Outlook (not the new Outlook toggle), run the Classic Outlook troubleshooters from the Classic Outlook troubleshooters page to detect and fix profile, version, or licensing-related issues.
9. If still not receiving mail
   • Contact the sender to confirm messages are actually being sent and not bouncing.
   • If none of the above resolves the issue, use the contact support option referenced in the troubleshooters article for deeper investigation (delivery issues, tenant configuration, etc.).
