We also encountered the same issue. On the global tenant, the plugin calls OfficeRuntime.auth.getAccessToken() normally, but there is a problem with the 21vianet tenant. The desktop outlook client works fine, but there is an issue with the Outlook web.

Thanks for reporting this @leapyear1969 and @mmhforjavaweb.

I'm going to transfer this to the office-js repo where we investigate product issues.
