Outlook Add-In Management

Outlook Add-Ins extend Outlook functionality to integrate with other applications/services.

Occasionally Outlook disables Add-Ins if they do not properly get loaded, or it may be desirable to disable an Add-In if it is no longer needed.

• Click on File menu
• Select Options

• Click on the Add-Ins tab in the left pane
• In the Manage drop down box, select Disabled Items
• Click Go...

• Select the Add-In you would like to enable
• Click the Enable button
• Click Close
• Click OK to close the Options menu

Enable Inactive Outlook Add-Ins

• Launch Outlook
• Click on File menu
• Select Options

• Click on the Add-Ins tab in the left pane
