Exchange 2016 new install - Hybrid Deployment check invalid login

On prem I have Exchange 2010 SP3 running as our hybrid server. Currently installing a new Exchange 2016 VM to replace it.

Office 365 tenant version 0.20 (15.1.361.13)

During install it says "Setup has detected that you've configured a hybrid deployment with Office 365..." Enter credentials of an Office 365 account that is a member of Organization Management. I enter the credentials of a global admin, but get the error "The username or password is invalid" even though I can login to the portal with the same username and password.

Tried several different global admins and all have the same error. Not sure where to go from here because I know the credentials are correct.


After much troubleshooting, I found that I cannot copy/paste the password into the Exchange 2016 hybrid config. If I type the password it works, if I copy paste, it does not.

I can copy the password from notepad, then paste into O365 portal and it works fine, if I paste into the installer, it says it is invalid. Strange bug in Exchange 2016 installer I guess.
