Outlook doesn't display your manager's team calendars

Original KB number:   3163350

Symptoms

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

Cause

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, select 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 select OK.
    • Windows 7: Select 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

    Note

    The 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 select 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, select Change.
  3. Browse the directory to find the user's manager, and then select the manager.
  4. Select OK.

To set the Manager attribute in Exchange Online, follow these steps:

  1. In the Microsoft 365 admin center, select Users, and then select Active users.
  2. Select the user's name, and then select Mail.
  3. In the More settings section, select Edit Exchange properties, and then select organization.
  4. Next to Manager, select Browse.
  5. Select the user's manager, and then select OK.
  6. Select Save, and then select OK.

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.
