I'm trying to update owners of appointments due to an import issue. I'm new to the Dynamics Export/Import process, but my understanding was that when I export to Excel, I need to reimport without changing any columns.
As a test, I only exported three records. When I tried the re-import with only the owner name changed, I received the invalid file error. I then tried only changing one character in the Subject, I still received the error. I haven't had this issue with other imports. Anything I might be missing with this?
