Running on windows, when I run the script from command line viewpoint works fine and I can check emails. But when I run under task scheduler, I get the failure in viewpoint
<NameError: uninitialized constant Viewpoint::EWS::Connection::Logging
Did you mean? Logger>
C:/Ruby24-x64/lib/ruby/gems/2.4.0/gems/viewpoint-1.1.0/lib/ews/connection.rb:36:in initialize' C:/Ruby24-x64/lib/ruby/gems/2.4.0/gems/viewpoint-1.1.0/lib/ews/ews_client.rb:49:in new'
C:/Ruby24-x64/lib/ruby/gems/2.4.0/gems/viewpoint-1.1.0/lib/ews/ews_client.rb:49:in `initialize'

All other gems run fine, I have reset permissions. Checked that logging is being loaded while under the task scheduler account. It is.
