Hi,

Exchange team has announced that this feature will be possible in the nearest future: http://blogs.technet.com/b/exchange/archive/2014/02/04/extending-message-trace-to-90-days-in-exchange-online.aspx

You can also be updated thru Office365 roadmap: http://roadmap.office.com/en-us

that is fine but we want to more than 90 day like 400 day, any other option available.

90 days is the limitation in Office 365 - nothing you can do about,.

any third party tools available for the same, to save trace logs in other location so we can retrieve message whenever required beyond 90 day,
