Yes, I'm aware of http://support.microsoft.com/kb/2606009 which doesn't offer a resolution.  The Exchange admin doesnt seem concerned with either of these errors to troubleshoot further.

As far as I can tell, my Exchange Calendar is working properly. No missing meetings, notifications, can browse others calendars, people can schedule meetings with mine, etc.

Any way to find out exactly what Outlook is unhappy about?

In File, Options, Addins, is the Exchange add-i

I have the same problem. I cannot find an answer anywhere in Google search.

I applied the 6/11/2013 Hotfix for Office 2010 programs from Microsoft on 6/18/2013 which updated my Outlook version to 14.0.7101.5000 (32 bit). I do not use Exchange or any servers. This is a stand alone installation.

BTW, my calendar is working FINE and have no problems with Outlook, only the Event Id 27 and the cryptic message - "Calendar Folder property is missing"

Anyone have any thoughts?

The add-in adds unified messaging, email permissions, and calendar availability. I'm not sure any of these features affect the error message and if everything is working, including Free/Busy, I probably wouldn't worry about the error. 

With the add-in disabled, outlook works and connects to exchange, only the features relating to voice mail, some calendar features relating to free/busy, and whatever email permissions affect (i think its Send As type stuff) are affected.

Note This release is not available at this time. We are investigating a problem with this release.

I think that answers your question. <g>

Was this update installed before your problems started?

Yes. There were no event log entries until after I installed the update.

Is there a way to undo the hotfix?

Is the update listed in Add Remove programs? If not, try System Restore, if you have restore points back far enough. Support filed a bug report for it but no resolution at this time.

The update was pulled for an unrelated problem, although I have no idea what that problem is.

All of the Office 2010 July 2013 CU's have been pulled.

I removed KB2817371 and it appears to have resolved the Calendar Folder property is missing event log spam.

Same problem is back after installing Office 2010 SP2 :(

Per the change log downloadable spreadsheet, "Service Pack 2 also includes a rollup of all Cumulative Updates through April 2013, and all Public Updates through May 2013".  Doesn't seem like that is a true statement as it must've also included some aspects of the July 2013 Outlook CU.

i have the same error too with sp2.

I'm not using Exchange

i have the same error too after installing Office 2010 x86 SP2: in the event viewer.msc a lot of advices about Calendar Folder Property is missing, after each time I run Outlook.

Before SP2 nothing about this very annoing problem

• Edited by oreste_ Friday, July 26, 2013 6:04 PM added eventi viewer

same issue on 7 computers running Office 2010 pro 32bit on Windows 7 64 bit, including 2 of my own computers

none of the computers are related to each other, each seperate clients of mine

all are stand alones and none are using an exchange account just a regular pop account

Seems this error msg is all over the internet on several sites

Whoever installed Sp2 seems to be having the same error msgs when opening Outlook

Well Nazir79 I hope that your test on the "Outlook-x-none.msp" from SP2 will be the solution of the problem.

I wanted to add my voice to the chorus to help validate the urgency for a solution whether from Microsoft or someone with knowledge and compassion that would not have otherwise allowed Microsoft push out a bad product.

Error ID 27

Calendar Folder property is missing

Calendar Folder property is empty

The warnings are generated when Outlook 2010 SP2 opens and each time I interact with Outlook [make a calendar entry, create a task, open  a contact]. The event log fills up like drinking water from a fire hydrant.

I know this was triggered by SP2 because I had examined the event log the day before the "update" and it was normal with no warnings. The only update I did was SP2 for Microsoft Office Home and Business 2010.

This is more than just an annoyance. I am concerned that future use will escalate issues to a point of major failure.

For what it is worth, I can sync successfully my outlook calendar and contacts with my Galaxy S4 using Samsung Kies.

please see the post and response by Tony Chen about this issue

Having the same issue after SP2 upgrade.  User got to have several shared calendars to manage.  Uninstalling SP2 will work but we need to have it fix....

I have this problem too and it is resolved(for me)  by uninstalling the July updates.

Look forward to hearing from MS that the problem is acknowledged and to seeing updates to resolve the problem. Until then I have hidden these updates and will not be re-installing them.

Does MS perform testing prior to releasing updates?  Curious that such a simple/obvious issue could slip past some pretty smart and capable people.  Sad to say, my Application Log looks like BSOD2600's (thanks for the "Data Visualization").

Where I used to work, we always performed "rollout tests" in a duplicate production environment to find/fix problem prior to release.  And the few times that anything did slip past that testing, we certainly pulled it prior to re-releasing.

They are not ignoring the issue and a fix is targeted for the August or September update (depending on further investigation and testing results). There is no negative side-effects known to this issue other then the Event

Robert, could you please direct me to an article that suggests this target fix date of August or September? I'd like to keep track of it so I can begin test deployments again as soon as this problem is resolved.

Currently, there is no article about this issue and it hasn't been fixed in the August update either nor will it be available for the September update/hotfix. The latest information I got was "it will take a couple of months".

The investigations still indicate that the issue is "purely cosmetic" but getting it out of the code takes a while.

To keep track of the issue yourself, open a support incident with Microsoft. Since it is a known bug, no support charges will apply but you might need to supply credit card information to register your support request.

Just downloaded the most recent Office updates today 9/11/13.  The problem is still NOT Fixed.  When I uninstall Office SP2, the warning goes away.  But my updates are always reminding me to update ..Uh!

Why has this issue gone on so long without a fix????

Sorry for the answer proposals-click of the mouse.

If you follow the thread http://social.technet.microsoft.com/Forums/office/en-US/f96903c9-c3ff-4e9d-9363-0882cffe4de8/ol2010-error-id-27-since-sp2-quotcalendar-folder-property-is-missingquot-quotcalendar you will find more on the subject error message. Both SP2 and KB2794707 generate this error message and both need to be uninstalled to stop it. Some machines may hang due to the error messages being generated and you can safely uninstall these updates without affecting Outlook, you simply won't have the other features that come with those updates. Microsoft are aware that there is a problem thanks to http://social.technet.microsoft.com/profile/oldguy23/?ws=usercard-mini and we are all waiting for a fix to the problem.

We have found that this error relates to shared calendars in Outlook. The more shared calendars you have, the more errors. Also, the errors are generated each time you LEAVE your calendar view. If you watch the event log, you'll see that visiting the calendar view does not cause the errors, but as soon as you switch back to your inbox, the errors are generated.

At least, this is the case in my environment. If anyone else cares to confirm, please do, but I doubt it will speed the fix process :-)

win7 32bit.

Office 2010 (14.0.7106.5001) 32bit 

no Exchange.

Same issues.

Appears after SP2 installed.

When click on Inbox in logs 27 generated.

No shared calendars

It may be related to calendars in archive folders.  If you have archive folders open, close them.  Close and open Outlook.  Check for Event 27.

The properties of calendars in archive folders do not have a Permissions tab.  I think the Permissions tab is the missing property referenced in the Event 27 message.

SP2 and KB27947070 may have some code that looks for permission on calendars, even calendars in archive folders.  Prior to them calendars in archive folders may not have been checked for permissions.

still comes up after closing all archive folders and restarting outlook.

also the errors still roll in even just being @ the inbox, not touching my calendar at all.

kind of annoying, but other than a few KB more logs per day doesn't seem to be a big deal.

We see that error appearing here as soon as someone adds a calendar from SharePoint to Outlook. The calendars work fine though.

-Peter

In our case, on further checking, the problem is not archive folders per se; it's the lack of permissions on calendar folders in .pst files. We use Exchange 2010, so the only .pst files users had were archive.pst.  If a user closed their archive.pst file, using Outlook did not generate Event 27.

If you don't use Exchange, you probably have a .pst file as your primary Outlook data file, so you can't do without it.

We don't use SharePoint, so the only comment I have is if there are no .pst files in use, I'd be surprised if Event 27 is generated.

In our case the event dissapeared after uninstalling KB2794707

I was able to reproduce the problem in the following way:

My Machine:   Windows 7 Ultimate SP2, Outlook 2010 SP 2 (KB2687455).

Steps:

Start Outlook

Create a new, empty PST file on my local hard drive, "MyTemp"

Create a new, folder for Calendar items inside the "MyTemp" PST file, call it "MyTempCalendar"

Create one new calendar appointment, call it MyTest.

Use the event viewer and look at the "outlook" application log.  note the time

Open (i.e. click) the MyTest appointment, note the time.

Look at the new entries in the "outlook" application log: ID 27, "Calendar Folder property is missing"

This repeats every time I open this appointment.  

Now wait for a FIX from Microsoft.

Same here. Waiting for a

Event ID 27, "Calendar Folder property is missing," after you apply Office 2010 SP2:

Good news it's acknowledged.  Bad news, there's still no fix.

What in the hell does this mean in English??

Your first sentence is gibberish.

i had a similar problem ..... i had set 4.2.2.2 as a statistic DNS on my pc

Even Outlook web access was not opening 

I changed it to obtain DNS server address automatically, that fixed the issue 

Two things seem to cause this issue for me:

• If I have users in Calendar Groups that are either no longer in Exchange (2013) or do not have calendar information set, then Outlook will kick out this error.
• There is a SharePoint company calendar that's pushed out to Outlook that appears to cause this as well. I can delete the calendar and the error goes away for the session, but it comes back once Outlook is closed and opened and the shared calendar is pushed back out.

In both instances, the error is only committed to the log when leaving the calendar view.

Another month passes and no resolution of this issue.

Yes it solved it for me. Thanks for posting the link.

Thanks for the Hotfix! Works fine!

Instant response, good documentation and fast fix of the problem... as you would expect from a market leader. *insertironicsmileyofyourchoice*

Hi,

For those who have trouble installing extracted file from "471202_intl_i386_zip.exe", you may also use a utility like Winzip to extract the file for a second time, and you would get this file: outlook-x-none.msp 

Right click the file and click Apply.

Hope this helps.

To go one (or a few) steps further, if you need to apply this hotfix to many computers on a network, try the following (working in my environment):

1. Extract the msp file from the exe as SoHard noted above.

2. Place the msp in a centrally accessible location.

3. Create a batch file (like OutlookHotfix.bat) with the following contents:

net use t: <insert path to msp file here>
c:\windows\system32\msiexec.exe /p t:\outlook-x-none.msp /qn
PAUSE
net use t: /delete

4. Create a .txt file with a list of computer names to receive the hotfix (each on separate line)

5. Run psexec (downloadable tool) with the following command from command prompt:

psexec.exe @<insert path to computer list> -u <insert admin username> -p <insert admin password> -c <insert path to batch file>

This will execute the batch file for each computer in the list, in order. The batch file maps the folder containing the msp file as a "t" drive, then executes msiexec with options to apply the msp. It then pauses (to avoid issues with trying to unmap before process completely finishes), and when user hits enter (i had to hit enter twice in some cases), then unmaps the "t" drive. Edit: The psexec command copies the batch file to the target machine (that's what the "-c" does), and executes it.

I ended up doing this because psexec will not directly execute the msiexec/msp command correctly, I believe due to using a unc path. If you place the msp file in a location that's already a mapped drive, you may not have to use this workaround, but in the interest of being thorough, I have included it here.

Hope this saves someone some time!

• Edited by OneJeremias Friday, February 07, 2014 1:25 PM included what the psexec command does

See this:

http://www.assistenzainformatica.tv/forum/errori-windows/3-calendar-folder-property-is-missing-evento-27.html

It's in italian.

Hmm, why even map a drive, just use the UNC ...

I had these errors in my event log without having SP2 installed. I installed SP2, then the hotfix and the errors are gone. Thanks Microsoft :)
