I want to apply policy tips to my office 365 trial account to generate the popup message when user sends some sensitive info  but it does not work . 

For this I have to create policy tip from EAC console . Then create the DLP policy and apply it.

Thanks  

Sunny

Hi Sunny,

Policy Tips is an Exchange Online/Exchange Server feature. For better support experience, I would suggest you post your question in the dedicated forum - Microsoft Online: Exchange Online, where you can get more experienced responses:

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.
