You can find it in : [Your Project Name] settings -> build -> plateform target (x86 | x64 | Any CPU)

If you are trying to determine the bitness of your code at run-time, use IntPtr.Size - 4 in x86 and 8 in x64.

Since Outlook loads your addin, its bitness will always be determined by the bitness of the parent process (outlook.exe). Unless there is a very particular reason to compile your code as x86 or x64, compile it as "Any CPU" - both 32 and 64 bit versions of Outlook will be able to load it.

If your addin is running, it means it was successfully loaded by Outlook, and the bitness of your addin will always match the bitness of Outlook. – Dmitry Streblechenko Jul 08 '21 at 15:29
