SendTo Mail Recipient not working after Windows 10 Creator July 2017 update

To Fix...

Ensure Outlook is set as the default Mail client

Close Outlook

For 32 bit versions of Outlook...
Delete Msmapi32.dll located C:\Program Files (x86)\Common Files\system\MSMAPI\1033\

For 64 bit versions of Outlook...  (I think this is the right path??)
Delete Msmapi32.dll located C:\Program Files\Common Files\system\MSMAPI\1033\

Run fixmapi.exe

Open Outlook (Outlook will replace & register the Msmapi32.dll and then open).

Try the "Send To > Mail Recipient" again.
