While most of us are getting ready for Fall, Office users are digging out from under an excess of mostly nonsecurity updates.
Not all the Office patches are ready to install; the Office 2010 SP2 release still has issues.
MS13-068 (KB2794707) and Office 2010 SP2 (2687455)
Office 2010 SP2 still suffering from minor flaw
Microsoft should soon push out Office 2010 SP2 to everyone getting Windows updates automatically. (Previously, those users might have seen KB 2687455 listed in Windows Update but unchecked for installation.) I’m still not ready to give the full thumbs-up to this major update. As noted in MS forums, some Office 2010 users who installed SP2 continue to receive false error messages in their application event log when they start up Outlook.
The good news: the error is cosmetic. There’s no actual error, but the Office event logs could become cluttered with messages such as “Calendar Folder property is missing.” An event log filled with false errors can make it difficult to find the records of other PC problems — they roll off the log sooner than normal and the event you’re looking for is gone.
This problem can also occur after installing KB 2794707, a September security update for an Outlook vulnerability. We have several shared calendars in my office, and my event log is filled with the Event 27 “Calendar Folder property is missing” error.
There’s currently no ETA on a fix for this issue. Because it’s consider cosmetic, it might be a low priority for Microsoft; however, I don’t find it reassuring to be told to ignore an error. Fortunately, the vulnerability patched by KB 2794707 is difficult to exploit, according to a Microsoft Security Research & Defense post.
What to do: There’s probably no real harm in installing KBs 2687455 (Office 2010 SP2) and 2794707 (MS13-068). But it’s just as probable there’s no real harm in waiting until Microsoft provides a fix for these fixes. I recommend keeping both updates on hold for a while longer.
