Outlook 2007 memory keep growing

[Worrow]

Hi,

 

I have an application keep fetching email from Outlook through MAPI for every 15 seconds. I let the program run for like 3 days or more, and I noticed the memory usage of Outlook keep growing--from between 50MB and 60MB to between 70MB to 100MB. My application however remains about the same memory usage for several days run.

 

What cause Outlook 2007 keep allocate more memory? Could I do something in my code to avoid this happens?

 

Thanks in advance.
