I'm trying with iOS Outlook SDK introduced at dev.outlook.com, their source code at https://github.com/OfficeDev/Outlook-SDK-iOS
I tried to register an application via Application registration tool with both an Office365 developer account and Outlook development account(request from Outlook) to get clientId, but none of them is working, I try to authenticate user but get error Application 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' is not supported for this API version
Could anyone let me know how to get a valid clientId to work with this SDK?
