the account cannot be used to authorize arcgis pro as it has already been configured in offline mode on some other device

Please i cant use my arcgis pro

That happens when you allow Pro to be used offline on one machine, then try to use Pro on another.

Just go back to the original machine and go back online.  Until you do so, the license will remain checked out.

If you can't... because the other machine is broken, or you are in another location and you can't get someone to check it back in there... then you have to call Tech Support

I'm sorry but that doesn't work, I'm on the machine it happened and I have been logged out.
