We’re making some changes to the Office 365 group creation process

Hi cfiessinger 

Since we can now set the language of a SharePoint Team site at the time of creation, this is our preferred way of provisioning groups. However, this language information is not passed to the mailbox creation process.

Mark-Kashman answered me that it should flow through but ssquires said it would not for now :-(

What would be the best way to have the Outlook welcome message in French when the default tenant language is English? 

If I scipt an update of the language right after creation of the site, will the welcome message be in the proper language?

If yes, can I invoke a Flow to do that and is there a connector for that?

Thanks
