Terribly slow when connecting and some questions

[SelaO]

I'm trying to connect to EWS like in the example: service.autodiscoverUrl("mymail@address.com", new RedirectionUrlCallback()); but it just hangs in that function for over 3 minutes and nothing happens. I see in the debugger it stays on static native int connect0(int var0, InetAddress var1, int var2) throws IOException;.

So a few questions:

1. Why is it taking so long?
2. Will this library work if we want to connect with Microsoft cloud like (1) in the link here? https://support.office.com/en-us/article/Archiving-third-party-data-in-Office-365-0ce338d5-3666-4a18-86ab-c6910ff408cc
