There are 115 languages currently in D365. D365 provides the ability for any user to set their preference to be any one of these 115 languages.
However, the System Administration module requires the system language to be specified.
Typically, the system language should be configured depending on where the Production environment has been deployed to. For example if production was deployed to:
- United Kingdom the System Language would be set to en-GB
- United States the System Language wold be set to en-US
- Canada the System Language would be set to en-CA
