Every time I am trying to sync my calendar, notes and mail account with my iPhone through iTunes I keep getting a notifactions saying 'Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client'.

The problem is that Outlook IS the default client.

Why can iTunes not complete this task for me...

Microsoft Office Professional Plus 2010 Build 14.0.4536.1000 64-bit.


Custom Made Computer., Windows 7, Intel Core 2 Duo E7400, 1TB HDD, 4.00GB Memory, 2 22" Inch Screens.

    That's because outlook 2010 is not supported in 64-bit, yet.

    Outlook 2010 is still in beta and so is not supported yet. You need to be using Outlook 2003 or 2007 until Apple releases an update compatible with the final Office 2010 sometime after that is released

    Outlook 2010 has supported 64-bit since day one, in fact it has 2 different versions to use. 32 & 64. Not just one for all.

    Thanks for the response.

    My love for Apple just grew even more, and that HTC HD2 is looking better by the day.

    Same here Macka.
    Apple's inability (or is it stubborn refusal) to get the iPhone to sync tasks properly with Outlook 2007 on a PC is also a joke.
    As for syncing anything with Outlook 2010 64-bit, I can't see that happening for a long time.
    I can now buy a HTC HD2 outright for a reasonable price so the iPhone looks like going to eBay or one of the kids.

    Unfortunately, from the information that I have gleaned, you will not be able to get the HTC HD2 to work either with the 64 bit version of Outlook 2010. Evidently, the Windows Mobile Device Center also needs to be updated to support a 64 bit version of Office and MSFT has yet to get around to it. Sorry - I'm in the same boat....

    Anyone still watching this thread? I'm trying to sync with Outlook 2002. Stopped syncing after I installed last iTunes update a few days ago. Can anyone help?

    I'm getting this and it's really annonying. The Nokia PC Suite provided a basic but functional PC calendar. Surely there's a simple PC client for the iPhone Calendar somewhere. I use Outlook Express and started using Outlook 2002 to manage my calendar but since a recent iTunes upgrade it's stopped working, giving this "default mail client" error. When I set Outlook to be the default mail client it made no difference.

    Apple - you've scored an own goal here. Something that did work now doesn't work, and the only thing that's changed is your software.

    I don't doubt it's down to compatability with M$ Outlook Add-ins, but they've not changed.

    As specified in all Apple's Support articles on syncing with Windows, you should be using Outlook 2003 or 2007 to sync with an iPhone:


    So, you'll probably have more luck if you use the software that's specified to work with it.

    If you do a search, there is a thread where someone contacted Microsoft and they were told by Microsoft not to use the 64 bit version of Office 2010 if you are syncing with the iPhone. You may use the 32 bit version, they stated it worked. There is no support yet for the 64 bit and the iPhone. Microsoft ways they will fix soon.

    I'm having this problem with the outlook 2010 beta... I love the 2010 version though.

    Is it even possible to downgrade and have Outlook 2007 read the newer .PST files?
