ExchangePerflog files being created in the TEMP folder

We are currently seeing a huge amount of ExchangePerflog*.dat files in the Temp folder of our service account.

"C:\Users\<service_account>\AppData\Local\Temp"

 

I have read a few articles online which suggest that this is related to Outlook 2003, but currently we are using Outlook 2007 SP3 on our EV server. I have checked if there are any performance counters running on the server, but could not find any active.

 

Please suggest what can be done for this?
