I am not receiving Teams invites from anyone

Hi @Helene Randle,

Welcome to the Microsoft Q&A forum.

I would like to provide you with the following information:

When someone sends you a Teams meeting invitation, it will appear in your Outlook.

Please follow the steps below to check:

1/ Check whether the invitation appears when you use Outlook Web.

2/ Check whether the email was accidentally moved to the Junk Email folder.

If so, right-click the email > select Report > choose Not Junk.

3/ Try clearing the Outlook cache.

To clear the Outlook cache, please follow these steps:

a/ For Outlook Classic:

• Step 1: Completely close Outlook
• Step 2: Press Windows + R
• Step 3: Enter the following path: %userprofile%\AppData\Local\Microsoft\Outlook\HubAppFileCache
• Step 4: Delete all files and restart Outlook

b/ For Outlook New:

• Step 1: Completely close Outlook
• Step 2: Press Windows + R
• Step 3: Enter the following command: olk.exe --devtools
• Step 4: Click on the Application tab
• 
• Step 5: Under Local Storage and Cookies, right-click and select Clear for outlook.office.com

You may also refer to the following documentation:

4/ Contact your organization’s IT department.

I noticed that you have tagged your post as Education, so I would like to provide additional information related to Education accounts:

Typically, Education accounts are managed and configured by the school’s administrators (such as the IT department or administrative office).

In this case, you can contact them for assistance in checking your Outlook license and performing a message trace to determine why the Teams meeting invitation is not delivered to your mailbox.

 After contacting your IT department, you may provide them with the following documentation:

I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.   

Thank you for your patience and your understanding. If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.

I look forward to continuing the conversation.

Try these checks and fixes, focusing on where Teams invitations can be blocked or misrouted:

1. Check Junk/Spam and blocked senders

• Ask senders to confirm the invite was actually sent to the correct address.
• In your mailbox (Outlook.com/Outlook on the web or Outlook client), check the Junk/Spam folder for missing Teams invitations.
• Review your Blocked senders list and remove any legitimate senders or domains:
  • Outlook.com / Outlook on the web: Settings > Mail (or Options) > Blocked senders / Block and allow.
  • Outlook desktop: Home tab > Junk > Junk Email Options > Blocked Senders tab.

2. Make sure your email address is correctly set on your account If your user profile does not have a valid email address, notifications (including Teams invites) may not be delivered.

• A User Administrator (Microsoft Entra) or User admin (Microsoft 365) should:
  • In Microsoft Entra admin center:
    1. Go to Identity > Users > All users and select your account.
    2. Confirm User type is Member (change from Guest to Member if needed).
    3. Select Edit properties > Contact Information and set the Email property to your correct address, then Save.
  • Or in Microsoft 365 admin center:
    1. Go to Users > Active users and select your account.
    2. On Account tab, under Username and email, choose Manage username and email.
    3. Under Primary email address and username, edit the username and domain so they match your correct email, then Save changes.

3. If the invites are for Teams webinars Teams webinar invitations are sent via the Microsoft Dynamics 365 email delivery service and can be quarantined by spam filters.

• Ask your organization’s email/security admin to:
  • Add the IP addresses used by the Dynamics email delivery service to the allow list in your spam filter.
  • If using Microsoft 365 Defender:
    1. Go to Anti-spam policies in the Microsoft 365 Defender portal.
    2. Open Connection filter policy (Default) (don’t tick the checkbox).
    3. Select Edit connection filter policy under Connection filtering.
    4. Enable Always allow messages from the following IP addresses or address range and add the Dynamics email IP ranges.
    5. Save, and if prompted, enable organization customization. If customization is blocked, the admin may need to run Enable-OrganizationCustomization in Exchange Online PowerShell and then add the IP ranges again.

4. Check for mailbox rules or redirects

• In Outlook/Outlook on the web, review Rules to ensure no rule is moving or deleting meeting invitations.
• Remove or disable any suspicious rules and test with a new Teams invite.

5. Ask senders to confirm delivery status

• Have a sender check if they receive any Non-Delivery Reports (NDRs) when inviting you.
• If they see delivery failures, your organization’s mail admin should review message trace and anti-spam policies.

If, after these checks, invitations still do not arrive, provide your IT/admin with the details above so they can verify your account configuration and mail flow at the tenant level.
