Here is the INDIANA code:
IC 35-47-2-21
Recognition of retail dealers' licenses and licenses to carry handguns issued by other states
Sec. 21. (a) Retail dealers' licenses issued by other states or foreign countries will not be recognized in Indiana except for sales at wholesale.
(b) Licenses to carry handguns, issued by other states or foreign countries, will be recognized according to the terms thereof but only while the holders are not residents of Indiana.
What confuses people is (b) and IF you have a misunderstanding of MI law. A MI CPL does NOT restrict a carrier to CC only.
