Can add-ins be installed with Outlook 2010? I read this: http://social.technet.microsoft.com/Forums/en-US/ilm2/thread/7a6fa67f-292e-4672-a112-281195a7ee13 and this http://technet.microsoft.com/en-us/library/ff512684%28WS.10%29.aspx and saw that it isn't officially supported.

FIM Add-in for Outlook: Supported: Office 2007 SP2, 32-bit Not Supported, but works (probably): Office 2010, 32-bit Does not work: Office 2010, 64-bit This comes from a FIM Webcast (talking about FIM RTM)http://setspn.blogspot.com

Thomas is correct. "While no official declaration of support for using the FIM Outlook Add-in with Outlook 2010 exists, it does work, but only for the 32-bit version. We suspect that support will be forthcoming with an upcoming update or Feature Pack (or whatever it is called – FIM 2010 R2 anyone?)." "Don’t worry about installing “Smart Tag .NET Programmability Support,” as part of Outlook 2010 because it isn’t there. However, this sub feature is a must for Outlook 2007." -- FIM Best Practices Volume 1 chapter 6 page 128 But you do need: microsoft forms 2.0 .net programability support .net programability support for office outlook.David Lundell, Get your copy of FIM Best Practices Volume 1 http://blog.ilmbestpractices.com/2010/08/book-is-here-fim-best-practices-volume.html
