Hi guys. Just got Office 2016 package installed and now all my models with external excel lookup files prompt for a password although file is not password protected. Even Setting a Password in those Excel files won't do the trick. Anybody with an idea what might be the reason? Thanks in advance.

Hi Diego,
To further investigate on this behavior, can you provide what Office 2016 variant and Monarch version are installed in your machine?
Also, can you confirm whether all the Excel files are not password-protected?
Thank you very much!
Regards,
