Solution 1Recommended

Modify Delegate Access Settings in Outlook

The primary method to hide private items is by adjusting the specific delegate's permissions within Outlook's Account Settings.

Outlook allows you to explicitly block delegates from seeing appointments marked as private. This setting needs to be configured individually for each delegate you have assigned.

1
Access Account Settings

Open Microsoft Outlook and navigate to 'File' > 'Account Settings' > 'Delegate Access'.

2
Select the Delegate

In the Delegates dialog box, click on the name of the delegate whose permissions you want to modify, then click 'Permissions'.

3
Clear Private Item Visibility

Uncheck the box that says 'Delegate can see my private items'.

4
Save Changes

Click 'OK' to apply the new permission settings and close the dialog boxes.

Frequently Asked Questions

Why can my delegate still see my private appointments after I unchecked the option?

This usually happens due to caching delays or overlapping folder-level permissions. Setting the delegate's calendar permission to 'None' and re-sharing the specific calendar is the most effective workaround.

How do I mark an appointment as private in my Outlook calendar?

When creating or editing an appointment, look for the 'Tags' group on the ribbon and click the 'Private' button (represented by a padlock icon) to hide its details from others.

Does removing calendar permissions affect a delegate's ability to manage my emails?

No. Delegate permissions are categorized by module (Inbox, Calendar, Tasks, Contacts). Setting the Calendar permission to 'None' will not impact their ability to read or send emails on your behalf if Inbox permissions are still active.
