Hi Subhash,
This is third party agent which is taking longer time to process the message. Therefore this 2 minutes time limit should be set on Third Party Agent code. What do you expect the agent to do if it's not able to do it's job in 2 minutes, let the message go
without disclaimer attached?
Best idea would be to have Vendor collect a dump and find out why it's taking more time to process the message. If it's waiting on some exchange component then Microsoft can be involved to look into those things.
