Can you try this patch with:

M-x package-install RET excorporate RET

Then:

M-x customize-variable RET excorporate-configuration RET

then select "Value Menu" and 3, which is "EWS URL OAuth 2.0 
settings (no autodiscovery)".  With your wis-edit.el patch applied 
I still get empty values for:

    INS DEL Argument name: 
            Argument value:

and:
 
    INS DEL OAuth 2.0 setting name: 
            OAuth 2.0 setting value:

and when I apply the setting the value contains: 

  (... (... (#1# . #1#)) 
   (#1# . #1#))

Maybe this is a more complicated case than the test case I 
provided (which does now work for me with your patch)?

Thanks,
Thomas
