- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Managing delegate access and privacy settings for personal calendar appointments.
- Observed behavior
- Delegates can view private calendar appointments unless their access permissions are explicitly restricted in Outlook settings.
Ensure you have the necessary account privileges to manage delegate settings and verify which users currently have delegate access to your Outlook calendar.
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.
Open Microsoft Outlook and navigate to 'File' > 'Account Settings' > 'Delegate Access'.
In the Delegates dialog box, click on the name of the delegate whose permissions you want to modify, then click 'Permissions'.
Uncheck the box that says 'Delegate can see my private items'.
Click 'OK' to apply the new permission settings and close the dialog boxes.

Restrict Calendar Permissions and Share Manually
If delegates can still see private appointments after modifying settings, you may need to completely remove their calendar permissions and share the calendar manually.

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.
