====== Mail-Addin not working properly in the Outlook desktop application ======

===== Symptoms =====

Some parts of the add-in doesn't work in the desktop application but works when you use the addin in Google Chrome. You might be able to see parts of the UI but can't save a todo.

===== Solution =====

Any add-in that runs in the desktop version of Microsoft Outlook actually runs in Internet Explorer.

Things to verify:

==== 1. Internet explorer 11 ====

Ensure that you have the latest version of Internet Explorer 11 installed.

==== 2. Verify that there is no browser emulation flag set. ====

Sometimes Outlook.exe is configured to run in emulation mode and therefore uses an older version of Internet Explorer than the version installed.

You can check that by opening the Windows registry and browse to 

  HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
     SOFTWARE
        Microsoft
           Internet Explorer
              Main
                 FeatureControl
                    FEATURE_BROWSER_EMULATION
                       outlook.exe = (DWORD) version

If the ''outlook.exe'' doesn't exist it means that it's not running in emulation mode, which is good.

If the key has a value it means that it runs in emulation mode. Solve this by:

  - taking a backup of the ''FEATURE_BROWSER_EMULATION'' folder and then
  - removing the ''outlook.exe'' key.

If you experience problems afterwards, restore the registry key with the backup.
