When I tried to add "BOX" to file storage in Adobe Acrobat DC, I got an error message "disabled by administrator".
I checked with my Box reseller and got the following answer.
"Adobe Acrobat DC is identified by BOX as an unpublished application, and obtain a client ID for this application from the application vendor."

What is the Client ID for BOX of this application?

Althogh your customer support instructed us to do the following, which did not improve the situation
1.Clear the browser cache
2.Temporarily change the default browser

The following applications are supported in our "BOX" environment.
Adobe Acrobat for Box
Adobe Acrobat desktop connector to Box

Please tell us the Client ID for BOX of this application.

Thank you for your cooperation.
