When setting up email integration in Zoho CRM, it's worth understanding that there are two entirely separate passwords involved, and Zoho Admins, and Zoho itself, don't have access to one of them.
For Gmail and Microsoft 365 accounts specifically, Zoho CRM now typically connects via OAuth authorisation rather than a stored password at all, so the underlying account password is never entered into Zoho CRM in the first place. This distinction is more relevant for providers connected via IMAP or POP, where a password, or an application-specific password if 2FA is enabled, is used directly.
Because passwords for IMAP or POP accounts can expire independently, and admins can't see or manage them directly, a user's email sync can quietly break without an obvious signal to the CRM administrator. Zoho CRM doesn't currently provide a clear "sync broken" indicator on the Email Sharing or Zoho Mail Add-on Users pages, so an admin managing many connected mailboxes may need to check periodically with individual users, particularly after they've changed their email password, rather than relying on the CRM to flag it.
