Hi
We have Exchange 2010 with Hybrid setup to Office 365. The on-premise servers are with Exchange 2010 and two Exchange 2013 Hybrid servers are there and we have few users moved to Office 365 and everything working fine,
Now we would like to install latest CU for Exchange 2013 servers. What would be the impact while installing CU on Hybrid servers?
Will there by any impact to cloud users, mail flow, free busy, mailtips and etc?
