How can I update my Google account email following a domain change?
To update your Google account email following a domain change, you should follow these steps:
If you use "Log in with Google", log out from Missive then log back in. This will update your login email.
Just reconnect your email account (this admittedly isn’t very intuitive): open your Accounts preferences, click Add account > Gmail or Google Workspace, and select your same account. This won’t duplicate the account, it will only refresh the domain. It doesn’t matter which options you pick for Email history, Team Inbox or personal, etc. These options will be ignored when connecting an existing account.
