Hello

I need idea:

I have got exchange 2013 hybrid config with adfs auth without sso. free/busy mailbox move is working correctly.

But after mailbox move to 365 all outlook client prompt password when trying to establish connection to outlook.offiice365.com after enter password connection establish.

I try: change rpc to mapi and back, AlwaysUseMSOAuthForAutoDiscover reg setting but not help.
I think exchange server config error but where....

Any idea?
