To search a Shared Mailbox, click the mailbox and use the Current Folder scope. This is a design limitation that will not change with future updates. Go to this Understanding Search Scopes blog for more details about what scopes are supported when.

To work around this issue, you can add the Shared Mailbox as a secondary Exchange account to the profile. First you will need to check if the shared mailbox is already listed as an account in the profile. If so, you will have to remove it. To do this, follow these steps:

• From the File menu, select Account Settings, then choose Account Settings again.

• Double click the Exchange account.

• Choose More Settings, and then select the Advanced tab.

• In the Open these additional mailboxes section, choose the shared mailbox and then select Remove.

Add Shared Mailbox as a secondary account to the profile by following these steps:

• From the File menu, select Add Account.

• In this dialog put the full name of the mailbox, e.g. support@company.com.

• When prompted for a password, choose the option Sign in with another account and use the Exchange account credentials that has permissions to the shared mailbox.

When you search a shared mailbox added as an additional mailbox you may see this error:

• "We're having trouble fetching results from the server. Some items may not be included in your search results."

This will occur if you're using a perpetual volume license (MSI) version of Outlook. This is currently a limitation with perpetual versions of Office.

To work around this, you can disable server search as a short-term solution. To do this, follow these steps:

1. In Windows, right-click Start, and then select Run. In the Open: box type regedit, and then click OK. This will open the registry editor.

2. In the registry editor dialog box, find this subkey in the registry, and then click it:

   • HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Search

3. Click Edit > New > DWORD Value.

4. Type DisableServerAssistedSearch for the name of the DWORD, and then press Enter.

5. Right-click DisableServerAssistedSearch, and then click Modify.

6. In the Value data box, type 1 to enable the registry entry, and then click OK.

7. Close the registry editor, and then restart Windows.
