I have onpremis exchange 2010 which is configured as hybrid with o365.some of my users are in o365 cloud.Now when im checking on the o365 admin portal dns settings, its saying we need to add some dns records in my public dns hoster.But since im having hybrid setup, i cant understand that thing.

Hi Darshana,

Since your question is more related to Office 365, I'd recommend you post it to the Office 365 Community forum:

http://community.office365.com/en-us/f/default.aspx

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
