I'm using MOSS 2007. Does anyone know if there is a limit to the number of user names that can be passed to the AddUserCollectionToGroup web service? I have around 300 and was wondering if I should break that into multiple calls and if so, how many? Thanks !!
I have verified adding 750-800 users at a time and face no problem and it shouldn't be a problem as well. You can also see the complete WSDL here
