title: How to change default email client in Dynamics NAV?
body: <p>We are switching from Ms Outlook to Lotus Notes as our default email client. The problem I have is that some customize button to print and send PDF are not longer working and instead return this message: "Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client"</p>
  
  <p>What I tried so far was</p>
  
  <ol>
  <li>Change the default email client in the ControlPanel --> DefaultPrograms --> Set Your Default Programs settings and made my Lotus Notes Mail and then clicked on the "Set this program as default". </li>
  <li>This did not work, so I went back into the same settings but instead clicked on "Set program access and computer defaults", from there I went under the section of default e-mail program and chose Lotus Notes, still no go. </li>
  <li>Went into regedit navigated to "HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\mailto\UserChoice" changed the key "Progid" (of type REG_SZ) to the value of "LotusNotes.URL.mailto"</li>
  <li>Googled it a lot but still cannot find anything that is working.</li>
  </ol>
  
  <p>Dynamics NAV seems to have the Outlook very deep inside it, but I really have no choice but to switch to Lotus Notes. Any help would be appreciate. We also have both Windows 7 and Windows XP at our location.</p>
  
  <p><strong>EDIT</strong>: 
  Looking into the codeunit has the function call of <code>Mail.NewMessage()</code> which again was working correctly with Outlook but I can't get it to work with Lotus Notes</p>
