Question details

The user wants to prevent a delegated user from receiving meeting invitations that are intended for the primary mailbox owner.

Product: Microsoft Outlook
Device & OS: not provided
Scenario: Managing mailbox delegation and configuring calendar meeting invitation routing.
Observed behavior: The delegated user receives meeting invitations addressed to the primary user in their own inbox, even when explicit calendar permissions were not granted.

Before you start

Ensure you are logged into the Outlook desktop client as the primary mailbox owner (User 1), as delegate settings can only be modified from the host account.

Solution 1Recommended

Disable the Delegate Meeting Message Option in Outlook Classic

By modifying the delegate permissions in Outlook Classic, you can stop meeting requests from being copied to the delegate's inbox.

When full mailbox delegation is granted, Outlook automatically forwards copies of meeting requests to the delegate by default so they can manage the calendar. You must manually disable this feature from the Account Settings menu.

Access Delegate Access Settings

Open the Outlook Classic client, click on the 'File' tab in the top-left corner, go to 'Account Settings', and select 'Delegate Access'.

Select the Delegate

In the Delegates dialog box, click on the name of the delegate (User 2) who is receiving the unwanted meeting invitations, then click the 'Permissions' button.

Clear Meeting Notification Option

Locate the checkbox labeled 'Delegate receives copies of meeting-related messages sent to me' and clear it (uncheck the box).

Apply and Save Changes

Click 'OK' to close the Permissions dialog, then click 'OK' again to close the Delegate Access dialog. Restart Outlook for the changes to fully synchronize.

Version and Synchronization Check: If the issue continues after updating these permissions, check your Outlook client version. Server-side delays may occasionally require a few minutes for the permission updates to take effect across Exchange.

Frequently Asked Questions

Why does my delegate receive meeting invites when I didn't specifically share my calendar?

When you grant someone access to your mailbox or set them as a delegate, Outlook's default behavior is to send them copies of meeting-related messages so they can help manage your schedule. This default setting must be manually unchecked.

Do I need to be an IT administrator to change these delegate settings?

No, the primary mailbox owner can change their own delegate settings directly from the Outlook desktop client under File > Account Settings > Delegate Access.

Will unchecking this option prevent the delegate from viewing my calendar?

No. If they have 'Reviewer' or higher permissions for your Calendar folder, they can still view your calendar. Unchecking this option only stops the meeting invitations from automatically landing in their email inbox.
