Outlook preparing icloud calendar for first use

I have installed iCloud on my Windows 7 PC and configured it to integrate with Exchange. When I start up Outlook and click on my Calendar, there is a little bubble in the taskbar saying “preparing calendar for first use”. Outlook keep freezing. I seems that everytime Outlook is re-preparing the new iCloud calendars. The Synchronization works fine. How can I resolve “Preparing calendar ….” error?

If you would like to combine a ‘private’ calendar next to your ‘exchange’ calendar in Outlook, you can choose the option “copy to my Calendar” and that seems to create an entry in your exchange Calendar.

  1. I think I’m facing the same issue
    (made a post here – https://discussions.apple.com/message/18272162#18272162)

    maybe with enough input from each other we can nail this down. I’m getting the message as well, more than annoying, it takes ages for my calendar to launch…
    I’ve been working on integrating iCloud (contacts and calendar) into outlook (tried 2007 & 2010). With 3 kids I have to integrate our home and work calendars if we expect to have any chance of remembering anything.

    I thought I had found a solution, using the basic windows iCloud control panel and then using a free piece of software from CodeTwo – http://www.codetwo.com/sync-for-icloud/ – which essentially just keeps any of your outlook folders (contacts, calendar, etc) in sync with one of the iCloud generated folders. One way either direction or Two way.

    This all worked just fine… except…through process of elimination I found that once the iCloud control panel has generated it’s iCloud ‘pst’ and Outlook is opening it; that Outlook takes an excruciatingly long time (minutes) to switch into the Calendar. I don’t see this behavior when switching to Contacts or back to Mail. This persists even if I turn syncing for anything outlook related off at the iCloud control panel, presumably because the iCloud folders are still present in outlook. It isn’t until I remove them, that things go back to normal.

    Curiously, I’m doing this on two different pc’s. One has normal Outlook (local files) and all works fine, while the other has an Exchange Server account, it’s the one that’s hanging.

    windows 7 64bit
    outlook 2007 & 2010 (with an exchange account)
    iCloud control panel 1.1 (64 bit)

  2. I have installed the beta version 2.0 of the control panel but it didn’t solve the problem. As this is really annoying (my Outlook now takes around 10 mins to startup but at the same time I don’t want to lose the iCloud sync), I have been playing around with some settings.
    Finally I have found a workaround that seems to work for me. If set OL to “work offline” before closing and then back to “work online” after starting up (of course incl. the error causing calendar view), the problem does not occur for me.
    Now trying to get this done programmatically with VBA. My first attempt was not successful though, now waiting for OL to start up again 😮

  3. This is the heart of my code in Outlook’s Application_Startup Event:
    myOlApp.GetNamespace(“MAPI”).Folders.GetFirst.GetExplorer.CommandBars.FindControl(, 5613).Execute
    Wait 8
    myOlApp.GetNamespace(“MAPI”).Folders.GetFirst.GetExplorer.CommandBars.FindControl(, 5613).Execute
    Of course you have to declare myOlApp (as Outlook.Application) and set it.
    The above code assumes that Outlook is online, then sets it first offline, waits for 8 seconds, before setting it online again.
    In my case I have added a “If” condition before it, checking for the current connection state. If Outlook is already offline, then I am asking whether it should switch to online.
