To work around this issue, use one of the following methods:

Method 1: Verify permissions in the registry

Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

In some cases, this problem is related to a permissions issue in the registry. To determine whether this is the cause of the issue and to fix it, follow these steps:
  1. Exit Outlook.
  2. Start Registry Editor. To do this, use one of the following procedures, as appropriate for your version of Windows:
    • 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 and right-click the following subkey in the registry, and then click Permissions:


  4. Under Group or user names, find your own user name or a group that you're a member of (such as Users or Administrators).

    If you're unsure about which groups your user account is a member of, follow these steps:
    1. Open Control Panel.
    2. From Category view, click User Accounts, and then click User Accounts again.
    3. Click Manage User Accounts.
    4. In the User Accounts window, find your User Name, and review the groups that are listed in the Group column.

      Note You may have to expand the Group column to view all the groups.

    5. Click Cancel when finished.
  5. If you do not see your own user name or a group that you're a member of listed in the permissions, click Add, and then add your own user account.
  6. Click OK.
  7. Select your user name or the group that you're a member of.
  8. View the permissions for your user or group, and make sure that the Read permission has Allow selected.
  9. Click OK.
  10. Exit Registry Editor.

Method 2: Run a repair of Office

Method 3: Revert the Office 2016 Click-to-Run installation to an earlier version

Revert the Office 2016 Click-to-Run installation to the 16.0.6741.2021 version. To do this, follow these steps.
