Outlook doesn't display your manager's team calendars

Applies to: Outlook 2016Outlook 2013Microsoft Outlook 2010


In Microsoft Outlook, your manager's team calendars aren't displayed in the Calendar module of the navigation pane.


This issue may occur for one of the following reasons:
  • The Show Manager's Team Calendar setting isn't enabled in Outlook.
  • You have a registry setting configured to disable the manager's team calendar.
  • The Manager attribute in Active Directory isn't configured.
  • The manager has more than 100 direct reports.
To resolve this issue, use one of the following methods, depending on the cause of the issue. If you don't know the cause of the issue, try each method in the order in which they are listed.

Method 1: Enable the Show Manager's Team Calendar setting in Outlook

  1. In Outlook, open the Calendar.
  2. On the Home tab, click Calendar Groups.
  3. Select Show Manager's Team Calendars.
Note If the Show Manager's Team Calendars setting is unavailable, follow the steps in the remaining methods until the issue is resolved.

Method 2: Modify the registry to enable the Manager's Team Calendar

Important  Follow the steps in this section carefully. Serious problems might occur if you incorrectly modify the registry. Before you modify it, back up the registry for restoration in case problems occur.
  1. Exit Outlook.
  2. Open Registry Editor. To do this, use one of the following procedures, depending on the version of Windows you're using:
    • Windows 10, Windows 8.1, and Windows 8: Press Windows key+R to open a Run dialog box. Type regedit.exe, and then click OK.
    • Windows 7: Click Start, type regedit.exe in the search box, and then press Enter.
  3. In Registry Editor, locate the DisableReportingLineGroupCalendar registry value. It's located in one of the following registry subkeys: 
    • HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook\Options\WunderBar
    • HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\x.0\Outlook\Options\WunderBar
    NoteThe x.0 placeholder represents your version of Office (for example, "16.0" = Office 2016, "15.0" = Office 2013, and "14.0" = Office 2010).
  4. Double-click DisableReportingLineGroupCalendar.
  5. In the Value Data box, type 0 (zero), and then click OK.
  6. Exit Registry Editor.
Note If the DisableReportingLineGroupCalendar registry value is located under the \Policies hive of the registry, it may have been created by using Group Policy. Your administrator must modify the policy to change this setting.

Method 3: Set the Manager attribute

Note You must be an administrator to complete these steps.

To set the Manager attribute on an on-premises Active Directory server, follow these steps:
  1. In Active Directory Users and Computers, open the Properties dialog box of the user account.
  2. On the Organization tab, under the Manager area, click Change.
  3. Browse the directory to find the user's manager, and then select the manager.
  4. Click OK.
To set the Manager attribute in Exchange Online, follow these steps:
  1. In the Microsoft 365 admin center, click Users, and then click Active users.
  2. Click the user's name.
  3. In the More settings section, click Edit Exchange properties, and then click organization.
  4. Next to Manager, click Browse.
  5. Select the user's manager, and then click OK.
  6. Click Save.

Method 4: Reduce the number of direct reports to fewer than 100

Note You must be an administrator to complete these steps.

If a manager has more than 100 direct reports listed in Active Directory, Outlook doesn't display the manager's team calendar. This is by design. If it's possible, reduce the number of direct reports listed in Active Directory for each manager to fewer than 100.
