Service Issue with Outlook Calendar Sharing Service

At the end of 2009, there was an issue with the Microsoft Outlook Calendar Sharing service, which enables Publish to Office Online in Microsoft Office Outlook 2007. This issue delayed or prevented customers from publishing a calendar to the service.

The problem was resolved in early January and we are implementing procedures to prevent a similar reoccurrence. We want to share some background on why this outage occurred.

As part of preparing the Microsoft Outlook 2010 version of the Calendar Sharing service, a configuration error was introduced on December 21, 2009, on the pre-production version of the 2010 Calendar Sharing service. An unintended side effect of this change also affected the production service. This prevented some Outlook 2007 customers from being able to login through Outlook and publish a new calendar or update existing ones.

Although customers immediately reported the issue through our support forums on TechNet, the automated monitoring system we use to determine if the service is up and working failed to detect this outage. This delayed our ability to find and resolve the issue in a timely manner.

By January 3, 2010, the issue was resolved for all customers. Everyone should be able to successfully publish calendars to the Calendar Sharing service.

Moving forward, we are taking steps to improve our automated monitoring to ensure that this specific scenario is detected. We are also reviewing other potential areas where our monitoring might be inadequate to detect outages in the service.

We are also changing our internal testing and deployment process for the service to ensure that changes for a new version of the service do not affect existing customers.

We apologize for any inconvenience this service outage might have caused.

  • Christian Miller said: "That being said, you can only use Windows Live Calendar to subscribe to Public calendars; meaning when you publish your calendar you must select the 'Anyone can subscribe to this calendar' field." Okay, I can now access my publicly shared calendar again using my Windows Live ID. But when I try to use the alternate method (calendars.office.microsoft...) which is contained in the invitation that I send to people when I publish my calendar, it still redirects them to the web site that says things will be changing after the release of Office 2010. So are you saying "things have already changed, even before the release of Office 2010"? I.E., from now on, the only way to view a published calendar is by logging on with a Windows Live ID?

  • Have been able to successfully publish a calendar. It was not updating yesterday, but seems to be updating today although the frequency appears to be fluctuating. When publishing, it indicates that the recommended update frequency is 20 minutes, but my last update was nearly an hour ago.

  • I am still having problems....anyone else having problems?

  • I've been testing every which way today; published a bunch of calendars all to individual Windows Live accounts. All of the calendars can be subscribed to from within Outlook and the calendar data is populated. But logging into Windows Live just shows a blank calendar for each and every account.

  • Obviously, things are still not right. Last week, publishing starting working again and when I viewed the calendar through a Windows Live account, it was updating. Today I've published the same calendar several times but it is no longer showing current information in Windows Live. In Windows Live, I right-click on the subscribed calendar and click "Edit" and it says the calendar was last refreshed at 5:09 pm today, but it is not showing current information any more.

  • I have read the comments above and surmise that I need to publish my work calendar so anyone can view in order for my wife to be able to subscribe as she used to. In the past I could publish my calendar SECURELY and she was granted access. I am more comfortable with that approach rather than the approach where anyone knowing the URL can log in and see. Can they also change if they are using outlook 2010?? This really doesn't work because my calendar needs to be secure for so many reasons. Questions: is there an update coming that will allow viewing from either windows live account or an iCals application (not Outlook)? Is there any security in the method you are suggesting? Can someone change my calendar if I do publish it the way you suggest??

  • After my watching my Outlook published calendar on my Windows Live calendar for a few days, the date and time of last refresh does appear to be updating, however, none of the calendar data is updating. Nothing has changed since I first published the calendar although there have been several changes to my Outlook calendar.

  • Okay, let's see if I can clear up a few things. Changes:

    The Office Online Calendar Sharing Web UI has been removed, meaning you can't view your published calendars on Office Online anymore; this doesn't mean you cannot view them elsewhere. If you try to access the old Office Online Calendar Sharing Web UI, you will be redirected to a help page. Private Published Calendars (Only invited users can subscribe to this calendar) can only be shared with users who have Outlook 2007 and Outlook 2010, and to users that have permission to view your calendar. Public Published Calendars (Anyone can subscribe to this calendar) can be viewed by anyone as long as you share the address/location of your online calendar (Example of URL: webcal://calendars.office.microsoft.com/pubcalstorage/q83dq64z190127/my_sample_calendar.ics; guessing this URL would be extremely hard). You have many options to view/subscribe to public calendars, one option we suggest is Windows Live Calendar; however there are others options. You can subscribe to Public Calendars via Outlook; you can also subscribe to them using a third-party calendar sites that support the subscription to .ics files; there are also other email/calendar applications which allow you to subscribe to online .ics calendar files. Please Note:

    We are aware that there are some problems with Windows Live Calendar not updating subscriptions in a timely manner or not at all. We are working with the Windows Live Team on this, and they are expecting a fix to be released in the next two weeks. Questions/Answers: So are you saying "things have already changed, even before the release of Office 2010"? I.E., from now on, the only way to view a published calendar is by logging on with a Windows Live ID?

    - No, I am not saying that. There are many other calendar viewing options out there that don't involve signing into a Windows Live ID. As long as you find a calendar site that allows you to subscribe to a .ics file, you can view the calendar. Please note, the calendar will need to be published so everyone can see it; this doesn't mean everyone will see it, it just means when someone tries to access the .ics file of your calendar they will not need to authenticate. Questions: is there an update coming that will allow viewing from either windows live account or an iCals application (not Outlook)? - You can currently view your calendar using Windows Live Calendar or a any application that supports the subscription to an .ics file. More information can be found here: office.microsoft.com/.../HA103887591033.aspx Is there any security in the method you are suggesting?

    - The only way to share your Private Published Calendar is from Outlook to Outlook. Public calendars can only be accessed if someone knows the address at which the .ics is stored. Example of Public Calendar URL: webcal://calendars.office.microsoft.com/pubcalstorage/q83dq64z190127/my_sample_calendar.ics Can someone change my calendar if I do publish it the way you suggest??

    - No, no one can change your calendar but you. People who subscribe your calendar may only be allowed to view your calendar. Christian Miller

  • > I've been checking this every day since March 3 and today, for the first time, my subscribed calendar is showing current data and getting updates. I hope this means the problem is indeed fixed. I'll monitor it for a few days before I let my people know.

  • We are using Windows Live Calenadr for the first time and it does not appear to updating calendar event at all. I imagine the sync is occuring thru the given email address??? nothing on outlook calenadr is appearing on Windows live calendar? Any help!

  • I've been checking our calendar every day since March 22 when I first noticed that the updating problem seem to have been fixed and it's been showing updates every day. So as far as I'm concerned, it's working okay now. I still wish we didn't have to log into Windows Live (or equivalent) to view published calendars, but I guess I'll get over it.

  • My calendar publishes on another computer, but does not include full details no matter what we do. We never had this problem before, now it only shows limited details.

    I have checked that the full details setting is chosen, but it still does not show the calendar with all of the categories.

  • I am UK based and my client is US based. Her calendar has been published using windows live and I have been given permission to share. I need to be able to edit her calendar however, this option is not available. As I am a freelance virtual PA, I really need to be able to edit a clients calendar in order to do my job properly. Is there a possibility this function can/will be added and when. Many thanks

  • I have moved my family from Comcast mail/tools to Windows Live and hoped to use the calendard to share work with my wife (both have Live accounts). The issue is that I want to share this securely and she is only using Live Mail / Live Calendar. Why can we not publish privately (ie. "Only invited users can view this calendar") with other secure Live members? My friend at work does this with Google calendar. I need to find a tool to share my constantly changing work schedule securely with my family's calendar (currently in Live).

  • Checked syncing of windows live todate with published calendars and they still do not seem to be talking to eachother. Anyone found a fix to this. Outlook says completed successfully but calendar still appears empty on windows live.com
