I am receiving the following event in my event log. I have ran a fix with ISINTEG as well as a full offline defrag on my public Folder Store but the error is still being logged. It look like an error with an "Out of office" notification (OOF) but it doest say what object it on. Also I dont see why an OOF would be detected on the public folder store. This message appears about every6 or 9minutes. Any help would be appreciated.
