I've been asked many times over the years how to get Outlook (up to 2010 anyway) to display a desktop notification for mail that arrives in any folder (due to incoming mail rules), as the in-built 'New Mail Desktop Alert' will only display for mail that is delivered directly to the Inbox.

Symptoms
If you have Microsoft Outlook 2013, Outlook 2016, Outlook 2019, or Outlook for Office 365 running on Windows Server 2012 or Windows 8, you no longer receive new email desktop alerts (toast notifications). Additionally, Outlook is no longer listed under Search and Apps Notifications.
Cause
This issue may occur for one of the following reasons:
The Outlook shortcut is missing from the following location, depending on your version of Outlook:
Outlook 2013: C:ProgramDataMicrosoftWindowsStart MenuProgramsMicrosoft Office 2013
Outlook 2016, Outlook 2019 or Outlook for Office 365: C:ProgramDataMicrosoftWindowsStart MenuPrograms
Desktop applications that send toast notifications must have a shortcut installed to the Start screen or in the Apps view.
The Remove common program groups from Start Menu Group Policy setting is enabled.
Resolution
To fix this issue, first you must determine whether the Remove common program groups from Start Menu Group Policy setting is enabled. To do this, follow these steps:
Exit Outlook.
Start Registry Editor. To do this, press Windows Key+R to open the Run dialog box. Type regedit.exe, and then press OK.
In Registry Editor, locate and then select the following subkey:
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorerLocate the NoCommonGroups value, and view its data.
If this registry value is set to 1, the Group Policy setting is enabled. If this value does not exist or is set to a value other than 1, the Group Policy setting is not enabled.
Exit Registry Editor.
If the Remove common program groups from Start Menu setting is enabled, disable it.
The Remove common program groups from Start Menu setting is located under User Configuration > Administrative Templates > Start Menu and Taskbar, as shown in the following screenshot:
If the Remove common program groups from Start Menu setting is not enabled, you can fix this by running a repair of your installation of Microsoft Office.
Note
To complete the repair process, you will have to restart Outlook, and you may also have to restart Windows.

The message contains diagnostic information for administrators, such as the following:
