Hi @Jitender ,

Based on my research and test, Teams uses UPN address to login in, so in order to separate Teams address from Email address, you may have to change the UPN addresses for users using the domain you want to use for Teams. For instructions about bulk change the UPN addresses, hopefully you can find the thread below helpful:

As regards to the Email addresses, you can consider bulk changing the primary email addresses for the users so that they can use the email addresses to send or receive messages. But per my test, users still need to use the UPN for authentication when accessing OWA or configuring the email account in Outlook.
