Exchange Online - Change primary email address, name and alias of a shared mailbox
When changing the primary SMTP address, it's usually a good idea to keep the old one as secondary, to avoid unnecessary NDRs. So in the syntax you used, make sure to add it as well, or you can use the -WindowsEmailAddress parameter:
Set-Mailbox user -WindowsEmailAddress newuser@domain.com
which basically changes the primary address to the value you specify, while preserving the old one as secondary. Then do the rest of the attributes as needed.

Thank you VasilMichev for your help!
I will add that parameter to the script!
