I also have a messageStore in mapi and ECE interface which I have just
ported to outlook2007 beta2, it seems to be working fine through ECE
although it no longer allows the useage of the v1.1.4322 .NET framework if
you are using it anywhere in your code, it must be .Net 2.0 compliant.

Have you any ideas of where it is crashing, have you captured a crash or
hang dump and looked at what caused the crash? Make sure you are catching
all exceptions as an uncaught exception will take out outlook in most cases.

Hello,

I have an addin wich use ECE interface IExtExchCommands in VC++.
This addin crashes immediatly in IExchExtCommands constructor in Outlook
2007.

Do you have any information about a compatibility problem with Outlook
2007 ?

Thanks
