How to stop receiving Event ID 27 Errors after uninstalling Office 2010 sp2

I'm in a Windows 2008 R2 domain and after installing Office 2010 sp2 on wsus3 client (windows7 client) I started receiving "Event ID 27 error messages string data: Calendar Folder property is missing" I then uninstalled sp2 via the WSUS3 server and the errors stopped. I later reinstalled it with all the other MS patches for September and errors started appearing again. I then uninstalled service pack 2 manually but the errors have continued. How can I resolve this issue?

The Outlook Team is aware of this issue and is investigating it for a fix.
There is no hard done to the system and log files will not flood over so my advise would be to have SP2 installed and wait for the fix comes out.

But its filling up/cloging up the event viewer with lots of these error messages and even removing it has not resolve the issue.

Your applicationlogs are no bigger then 20MB by default so this could do no harm because once full the logserver will delete the latests info.
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

I have found a temporary work around. It involves uninstalling security patch kb2794707 and office 2010 service pack 2. All Event ID 27 warnings will definitely stop. The one drawback is that you would receive all of the emails that you have already received for the month of September once again.

Any updates on this?

It is still happening on my Windows 8 and Windows 7 computers using Outlook 2010.

I contacted MS and they said they was working on this but wow it has been a long time.

Like I have indicated in my previous post above it is a definite workaround that does actually work although its not the desirable fix. That will have to come from Microsoft.

Because it definitely works as a work around.
I believe I may have a clue to the problem.  

My configuration is Windows 2008 R2, Exchange Server 2010, Outlook 2010 on each workstation.

Through trial and error here is what I have discovered.  
1.  I cleared the Application log of all entries.
2.  When I opened Outlook, which also opens my data file "Archive.pst", the event 27 entries were added to the application log.

3.  I cleared the Application log of all entries a second time.
4.  I went into the control panel, clicked on Mail, and removed the data file "Archive.pst".
5.  I opened Outlook
6.  I checked the Application log, and there were NO event 27 entries.

7.  Just for fun, I decided to run folder cleanup again, and selected to archive only the "Drafts" folder (which contained no mail items).
8.  I chose a NEW Archive filename and clicked Ok
9.  The cleanup ran just fine, and when I checked the Application log, sure enough, several event 27 entries appeared in the log.

Workaround:  Remove all Data Files from the Outlook account, and NO 27 entries will appear in the Application Log.

Of course, we all like to archive our mail, so we just wait, and wait, until Microsoft provides a solution.
NB: I too got event 37 calendar folder property is missing with SP2 and uninstalled it. Then, this week, with 11/14's rollout of patches, I installed KB2837597 security update for Outlook 2010 and my event log filled with event 37 errors of calendar folder property missing. Uninstalled that update and errors again were gone. I have a question for Microsoft: with a user database that dwarfs almost all other email clients, PIMS and organizers put together, why aren't they giving this priority? (Because it doesn't generate a revenue stream?) Outlook is cranky enough without MS building bugs in Outlook updates.
