I'm going through setting up templates with the ARM v2 Template Generator and all is working apart from being able to enable MAPI without setting the "Allow user to Toggle MAPI" too:
If I tick enable MAPI without the "Toggle" option:
The template generates the following output:
and when I go to create a new user the option is there, but its not editable or enabled
However, if I edit the json file and set "DefaultValue" to "true" I get the outcome I want
Is this a bug or by design?
