Outlook not showing accepted invitations

I send out invitations for online client meetings. Once accepted the meetings are marked as confirmed. If clients don't confirm, I keep following up until they do. Some of my clients (always the same ones) accept but the acceptance message doesn't come through and the meeting shows that the client has not accepted the invitation. How can this be resolved thank you.

    Hi Koala2861

    Thank you for posting your question in the Microsoft Q&A forum.

    Based on your description that your Outlook application is functioning correctly. The issue stems from the specific button your clients are clicking when they accept the invite.

    Please note that your Outlook calendar can only update to "Accepted" if it receives a digital receipt from the client. It appears these specific clients are selecting the option "Do not send a response" or uncheck the "Email organizer" box. When they choose this, the meeting goes onto their calendar, but the acceptance message will not come through, and your Outlook cannot receive the signal to change the status from "No Response" to "Accepted".

    Since this is a client-side action, I recommend sending a quick note to the clients who frequently do this to ask them to please ensure they click "Send Response Now" or check the "Email organizer" box.

    For MacOs devices: (click to edit RSVP to edit response)

    I hope this clarifies the situation! If you have any further questions, please feel free to let me know.

    If your clients are accepting meeting invitations but the acceptance messages are not coming through, and the meetings still show as not accepted, there are a few troubleshooting steps you can consider:

    1. Check the Receive Folder Table: Use MFCMAPI to verify that the IPM.SCHEDULE.MEETING entry exists in the Receive Folder Table. If it does not, you may need to set the receive folder correctly.
    2. Delete Old Associations: If the entry is present but still not functioning correctly, you can try deleting any existing associations for the IPM.SCHEDULE.MEETING class in the Receive Folder Table and then refresh it to see if that resolves the issue.
    3. Inspect Inbox Messages: Look for messages in the Inbox that have the message class IPM.Rule.Version2.Message. If any of these messages have a PR_RULE_MSG_PROVIDER property value of Schedule+ EMS Interface, deleting them might help resolve the issue.
    4. Client Configuration: Ensure that your clients are using compatible email clients and that their settings allow for proper handling of meeting invitations. Sometimes, issues can arise from the client's email configuration.

    If the problem persists after trying these steps, you may want to consult with your IT department or Microsoft support for further assistance.
