Cannot create unknown type ‘{http://schemas.microsoft.com/netfx/2009/xaml/activities}OutArgument({clr-namespace:UiPath.MicrosoftOffice365.Models;assembly=UiPath.MicrosoftOffice365}Office365Message)’.
Welcome to the community
Looks like one of the Arguments you created is wrong or is having issue…if you have changed the office 365 version from 1.11.1 to above versions there are changes in drive item types…please check the same and recreate those variables again to get the right type
cheers
