Federation certificate expired for hybrid Exch 2016 server
Hi we have problem with already expired exchange federation certificate for hybrid Office 365, also expired exchange oauth certificate, i have renew oauth certificate already but how to proceed with renewing federation certificate, federation trust was created in exchange 2010 era, now we have exchange 2016 on windows 2012r2 server, can we simply renew trust to o365 with builtin hybrid wizard through ecp on exchange or we must somehow renew federation with o365, i have read that newer exchange does not need to create federation trust anymore (this was exchange 2010 era), how to proceed with this and dont broke something, email are flowing but we see some rdns hello errors on our sophos utm email gateway. Thanks OSO1KViews0likes2CommentsProblem with kb KB5018411 on domain controllers

Hi, we have problem with application server which resides in tree domain dm1.domain.com, we need to manipulate users and groups (crerate user, add to group e.t.c) in our root domain dm.domain.com, this application server (linux based) uses AD ldap to connect to tree domain, there is no direct connection to root domain controllers. Wee need to create users and groups through this application server in root domain. Is this possible to configure somehow? Thanks2.3KViews0likes10Comments
