I am not receiving emails when new meetings are added to my calendar on Teams/Outlook. I have gone through all my settings and can't find the problem. Anybody else have issues with this?

    Hi @Valdez, Jennifer M,

    Welcome to the Microsoft Q&A forum.

    Based on your description, I understand that the meeting has been added to your calendar; however, you did not receive any email notification.

    Could you please provide the following information so I can assist you further:

    1. Which version of Outlook are you currently using (Outlook Classic, New Outlook, etc.)?
    2. Please check whether the issue also occurs when using Outlook on the web.
    3. Kindly verify if there are any active rules that might be causing this issue

    Additionally, you can try the following steps and check if the issue is resolved:

    1. Please check your Junk Email folder to see if the notification emails were mistakenly delivered there. If so, please mark them as “Not Junk.”
    2. You can perform a message trace through the Exchange Admin Center to check the status of the notification emails. Running a message trace will help determine the delivery status and identify why you did not receive the email.

    To perform a message trace, you may refer to the following documentation:

    Message trace in the new EAC in Exchange Online | Microsoft Learn

    (Note: Message trace can only be performed by a tenant administrator. If you are not an administrator, please contact your IT department for assistance.)

    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.

    For Teams/Outlook meeting invitations and updates that are added to the calendar but no email is seen, the most common causes are spam/junk handling, rules, or filtering in the mailbox.

    Work through these checks in Outlook/Outlook on the web:

    1. Check Junk/Spam and "Other" inbox
      • In Outlook.com/Outlook on the web, check the Junk Email folder and move any valid meeting invitations back to Inbox using Mark as not junk.
      • Also check the Other tab (if Focused Inbox is enabled) and any custom folders where rules might move messages.
    2. Check blocked senders
      • In Outlook.com or Outlook on the web:
        1. Sign in to the mailbox.
        2. Select Settings > Options or Mail.
        3. In the left menu, select Blocked Senders or Block and allow.
        4. If organizers’ addresses or their domains (for example, @contoso.com) appear there, remove them from the blocked list.
      • In Outlook desktop (for Microsoft 365/Outlook 2016):
        1. On the Home tab, select Junk > Junk Email Options.
        2. Open the Blocked Senders tab and remove any legitimate organizers or domains.
    3. Check rules and forwarding
      • In Outlook.com/Outlook on the web, review Rules and Forwarding settings to ensure meeting invitations are not being:
        • Automatically moved to another folder (including RSS or archive folders).
        • Forwarded to another mailbox and deleted.
      • In Outlook desktop, review File > Manage Rules & Alerts for any rules that might move or delete meeting-related mail.
    4. If this is about Teams webinars specifically
      • Webinar invitations are sent via the Dynamics 365 email delivery service and can be quarantined by tenant spam filters.
      • An admin should:
        1. Go to Microsoft 365 Defender → Anti-spam policies.
        2. Edit Connection filter policy (Default).
        3. Under Always allow messages from the following IP addresses or address range, add the IP ranges used by the Dynamics email delivery service as documented in the public IP list.
        4. Save and, if prompted, enable organization customization (or run Enable-OrganizationCustomization in Exchange Online PowerShell, then retry adding the IPs).
    5. If meeting responses/updates are missing from Inbox
      • For some Outlook desktop scenarios, the receive-folder mapping for meeting items can be wrong. Admins can use MFCMAPI to verify that the Receive Folder Table contains an entry for IPM.SCHEDULE.MEETING pointing to the correct folder, following the documented procedure. This should only be done by someone comfortable with advanced mailbox tools, as incorrect changes can damage the mailbox.

    If, after these checks, invitations still do not appear anywhere in the mailbox, the organizer should be asked to confirm any non-delivery reports and, if using Outlook.com, follow the sender guidance in the Outlook.com sender support article.
