My company changed our email domain. Is there a way to update all user email addresses?

[Al Gresto]

My company recently changed our email domain because we changed our company name. For example, my email used to be al.gresto@kusbottles.com. It is now al.gresto@kushco.com. I was able to change my own email address, but my team is wondering if there is a way to transition all @kushbottles.com domains to @kushco.com domains? Or a way for IT to manually change email addresses to avoid asking every employee in our company to change their email address on their own?

Thanks in advanced.

Not a supported way out of the box. There is an unsupported option. Make sure you have a backup and then make the changes to a copy of the backup
