Commented Unassigned: MAPI_E_INTERFACE_NOT_SUPPORTED == 0x80004002 [17722]

As the title shows, I'm receiving an error (MAPI_E_INTERFACE_NOT_SUPPORTED == 0x80004002) when trying to export the AutoComplete cache.

I get 3 different dialogue boxes that all say that same error, and my only option is to click OK or X out of it.

When I close all of the boxes, and go to the destination folder where I had told it to export to, I notice I do have data in there.

I'm not sure if this will cause problems with the import of this file I just exported or not..but I wanted to check to see if there was anything I could do about this error message before I go and try this export method on a clients account.

Thanks!

I've just had the same issue. It turns out that the interface dialog contains the descriptive name for the interface and not just the address. When you are prompted for the interface delete anything after the brackets. So the = sign and anything after it should be gone. Then you will get a clean export without any errors.
