** UPDATE: Office 2010 x64 support is available in the v5.2.0 production release **

Preliminary Office 2010 32 bit support is available in the v5.0 release. See this cross post from our beta forum for information on Office 2010 64 bit support:

Thanks so much for the feedback. Office 2010 64 bit beta testers are truly on the "bleeding edge" of software testing!

It is clear that there is a great deal of interest from our customers for 64 bit support. As we have said from the beginning, we will support the Office 2010 64 bit RTM release due out sometime next year. That said, 64 bit support will not be available in the initial v5.0 release. Once we get v5.0 out the door, we will investigate the steps required to convert to 64 bit and post our findings/timeline for support.

FYI - there are a couple of things that make 64 bit support harder than you might expect:

* Office 2010 is in BETA, meaning that we are currently developing against a shifting target.
* Many of the Microsoft development tools that we use have not been adapted for 64 bit support yet.

I suspect the above impacts every Office development shop, slowing 64 bit support for most add-ins.

I want to reiterate - we hear your requests loud and clear and we will support 64 bit Outlook 2010 just as soon as it is possible to do so! Thanks as always for your feedback.

Please comment here if you would like to be notified when 64 bit support is available. Thanks.

I was a little dissapointed to see x64 not support at release of 5.0.

<Tip for advanced users />

Windows 7 x64 tip as a gap fill until until ClearContext is released / supported under x64 OS's. There is a feature in Windows 7 (Windows Virtual PC XP Mode Applications) ... nload.aspx that once installed will setup a x32 XP virtual sandbox within your Windows 7 environment. I installed the x32 bit version of Microsoft Office 2010 beta 2 in the Windows Virtual PC XP environment and then it's possible to run from the Windows 7 host (x64) just a single application (Office 2010 Beta 2) within the x32 virtual environment that makes it appear to the user that it's running natively in Windows 7. Opening new messages, reminders, and even the poppup toast with new mail in the task bar runs as it should in Windows 7.

Again this is not ideal due to the overhead of having a virtual environment running consuming system resources but it's a good work around for the short term until x64 CC is released.

Rogerla - I think the easier thing to do is to downgrade to the 32 bit version of Office for the time being. 64 bit Office isn't required to run on 64 bit Windows and unless you are using more than 4 GB of RAM, doesn't provide a lot of advantages. Slipstick, an excellent resource for all things Outlook, has this to say in their latest newsletter:

Will my add-ins work with Outlook 2010 Beta?
I mentioned this a few weeks ago but it’s worth reminding users: Do not install the beta on a mission critical machine and do not install the 64-bit version of Office 2010 if you need to use add-ins or applications that access Outlook data. This includes sync software for PDAs and Smartphones. Add-ins will need to be rewritten and compiled as 64bit add-ins before they will work in the 64-bit build of Outlook.

Your best chance of add-ins and sync working as expected is to use the 32-bit build. There will be some add-ins that don't work with it, but most will. Most developers will update their add-ins for Outlook 2010 32-bit promptly, but 64-bit versions many not be available for months

x86 Office 2010 beta2 on x64 host would probably be a good option for most users who don't mind running betas on their primary machine(s) and incurring the additional marshaling overhead.. for those that would like a side by side release vs beta solution or for folks like me who develop applications and need to have x64 office on the host on host in a sandbox setup works best.

On the Microsoft site ( once you get to the download page, they say (bolding mine):

64-bit Office
A 64-bit version of Office Professional Plus 2010 Beta is also available. The 32-bit version offered above is recommended for most users on both 32-bit and 64-bit operating systems. The 64-bit version enables users to take advantage of the increased memory capabilities of 64-bit operating systems. Excel users who need to work with extremely large files (larger than 2GB) should consider testing the 64-bit version. However, users should expect compatibility issues with Office add-ins. Please review the TechNet article on 64-bit editions of Office 2010 before downloading.

I'm running the 32-bit Office 2010 on 64-bit Windows 7 with no glitches (I still don't like where the CC toolbar buttons are on Office 2010, but they work correctly)

The Office team just announced that they will be releasing Outlook 2010 on May 12. Will you have a 64 bit version of Clear Context by then? ... orrow.aspx

Thanks for your interest. We don't have an estimate at this time for 64 bit support. We remain committed to supporting it, but we have not been able to obtain a date on when the development tools we require will be updated to support it. Please see this blog post for more detail on Office 2010 64 bit and the pros and cons of installing it:
The Office 2010 team has posted comprehensive information regarding the 64-Bit release of Office, including details on who should install Office 2010 x64:

“If you’re trying to decide between 32-bit and 64-bit Office, you should ask yourself what your needs are. Are you an Excel power user working with huge amounts of data? Do you need to work with file sizes greater than 2 GB? If so, then you would benefit from 64-bit Office being able to utilize more memory. If not, we’re recommending 32-bit Office 2010 as the default installation on both 32-bit and 64-bit Windows mainly due to compatibility with existing 32-bit controls, add-ins, and VBA.”

Additional detail:

“Both 32-bit and 64-bit versions of Office are largely indistinguishable, except that 64-bit Office has a much higher memory capacity. As mentioned above, the extra memory capacity comes at the cost of some compatibility with existing extensions to Office, such as 32-bit versions of ActiveX Controls and some 3rd party add-ins, in addition to 32-bit versions of programs that interface directly with Office. New versions of these extensions will need to be obtained, and it will take some time for 64-bit compatible extensions to be made available.

For these reasons, we recommend running 32-bit Office 2010 even on 64-bit Windows operating systems for better compatibility. On 64-bit Windows, more applications and documents may be opened at once, and switching among them will be faster because the machine can have more physical memory for the processes to share. When the 64-bit ecosystem for Office is more mature, you’ll be able to easily migrate to 64-bit Office!”

In the near term, if you want to run ClearContext in Outlook 2010, you should install the 32-bit version of Office 2010. For information on future ClearContext support for 2010 x64, see this forum post.

Office 2010 is RTM. Any updates on CC x64 support?

Though we do plan to support 64 bit, the tools we require to convert are still not available.

Please note that MSFT advises that all customers install the 32 bit version unless they absolutely require the additional memory capabilities of 64 bit.

Obviously I'm interested in O2010x64 support. I'm commenting just to be notified.

But I have a question: is Office 2010 32bit fully supported in CC v5.0.2? I read that there's only preliminary support in v5, could you please clarify?

v5.0.2 was released when Office 2010 was still in beta. Because we didn't have the final version of 2010 in house, there was a possibility that the future release would break CC functionality in some way. It did not and v5.0.2 fully supports Outlook 2010 32bit. We do plan to make some minor enhancements in v5.1.

Please notify when x64 support is ready -

Any ideas as to when it will be in beta form?
