Hello,
At an customer of ours we have an problem that on monday 08:00 the CPU is pulling 100% and Outlook is not workable on the clients. When we dive deeper in this issue we see that the IIS Worker Process is pulling this CPU, more specificly the MsExchangeMapiFrontEndAppPool on the application pool. When we reboot the server everything is solved till the next monday morning 08:00.
We can't figure out what is causing this issue and why this only happens on monday around 08:00. We can't find any scheduled tasks as far as we know.
I could appreciate some help here.
