Linking Sharepoint to Lotus Notes

I recently ran into an issue when trying to create a link in SharePoint to a Lotus Notes document (a Work Request.) The same is true for SharePoint links to both Lotus Notes servers and databases.
 
SharePoint treats the Lotus Notes link as an Invalid URL because of the nonstandard Notes://servername format.
 
The following is a workaround that will allow you to add links to Notes using the Notes:// URL. 

1. Create an HTML file with a link to the Lotus Notes Document/Database.  
   The HTML should look something like this:
   <A href=”Notes:///yournotesserver/notesdocument”>Link to Document</A> 
2. Upload the HTML file to your SharePoint site’s Shared Documents repository. 
3. Click the HTML file in the Shared Documents repository to view it and make note of the file’s URL. I recommend that you highlight and copy the URL.
4. Add the “Page Viewer Web Part” to the SharePoint site’s Web Part Gallery.
   Site Actions > Site Settings > Web Parts > New > Microsoft.SharePoint.WebPartPages.PageViewerWebPart 
5. Edit the Home page of the SharePoint site.
   Site Actions > Edit Page
6. Add the “Page Viewer Web Part” to the home page.
   Add a Web Part > PageViewWebPart 
7. Add the HTML file’s URL to the Web Part Properties. Paste the URL you copied in Step 3 above.
   Edit > Modify Shared Web Part > Enter the URL 
8. Exit Edit Mode
    
   Clicking your new link should take you directly to the Lotus Notes Server, Database, or Document.
