We use SQL Server Management Studio 2008 R2. IntelliSense works with SA account perfectly. But it is not working with Windows Authentication user. The user has access master db
You can try solution from these questions1 or questions2 and questions3.
Or please try these steps as below:
My schemes were too big. I had to do this:
Tools >> Options >> Text Editor >> Transact-SQL >> Intellisence
Maximum script size: Unlimited
It could also depends on your destination server.
For instance for server 2005, intellisense will not work. Here is a command to check this :
SELECT SERVERPROPERTY('ProductVersion');
If version begin with 8 or 9 it will not work.

A workaround could be to use a sql server plugin as Autocomplete version express
