Hi,

if I create macro in Outlook 2010 32-bit and sign it using code signing certificate, everything works great in 32-bit version of Outlook 2010. But if I copy vbaproject.otm to computer with Outlook 2010 64-bit, Outlook reports error "Warning: the digital signature has been tapered with after the content was signed. This content cannot be trusted".

Same thing happens if I sign code using Outlook 2010 64-bit and then try to run it using Outlook 2010 32-bit.

Is there any way I can use same signed OTM file using both 32 and 64 bit versions of Outlook?

Thanks,

Denis
