Supported character sets for remote domains in Exchange Online

Remote domains define settings based on the destination domain of each email message. All organizations have a default remote domain named "Default" that's applied to the domain "*". The default remote domain applies the same settings to all email messages regardless of the destination domain. However, you can configure specific settings for a specific destination domain.

For more information about remote domains, see Remote domains in Exchange Online.

For remote domain procedures, see Manage remote domains in Exchange Online.

The following table describes the character sets that you can configure in remote domains.
