Hi!Here is how is it determinedhttps://docs.microsoft.com/en-us/azure/active-directory/b2b/invitation-email-elementsAnd here is how it can be changed via the Azure Active Directory B2B collaboration API https://docs.microsoft.com/en-us/azure/active-directory/b2b/customize-invitation-api
And Message Language is here
Array of Recipient
An array of additional recipients the invitation email message should be sent to. Currently only 1 additional recipient is supported.
Customized message body you would like to send rather than the default message
ISO 639 language format. Default is en-US. Ignored if the customizedMessageBody property is populated.
Hope it helps and answers your question!Best, Chris
