I’ve now got more evidence of this:
Note that this is on Vista, which has proved substantially better for Outlook 2007 than XP. You might think there is nothing very exceptional about Outlook.exe grabbing nearly 40% of the CPU time, but consider the context:
I took this screenshot while troubleshooting another problem. Interesting point: I had not opened Outlook since the last reboot. Msconfig does not show it as a startup app either. Maybe this is some Office pre-loading trickery; or more likely it has been started by Vista’s desktop search engine. Yet this is meant not to interfere with your work.
RSS sync in Outlook is turned off.
Outlook isn’t grabbing this CPU all the time, but in regular brief bursts.
I’d like to know what it is doing.
