Timeout early on custom activity

I made a custom activity for e-mail activities so that all of the bots for the business are consistent and can be updated and managed more easily. Prior to this we had a xaml in each bot program with the same exact programming. Specifically, the issues resides around the timeout of the e-mail activity within those activities. For reading e-mail, we have it set to 5 minutes because one bot can have up to 150 e-mails to manage at a time. With the xaml in the program, it would take about 3 minutes to read the e-mails when there were that many to read. With the new library activity, it now times out at 2 minutes, regardless of the fact that the timeout in the activity is set to 5 minutes. Can anyone explain why this would be happening?
