Inbound emails getting ignored and moved to junk folder due to inactive user locked outIssue Incoming emails to the instance may get skipped and not be processed, with their state in received-ignored. The email logs traces errors like:Skipping <Inbound_Action_Name>, User Guest User with email guest@example.com is locked outSkipping <Inbound_Action_Name>, User Guest User with email guest@example.com is inactiveCauseWhen a user sends an email to the instance from an email address which is not present in the sys_user table, the system impersonates the Guest user account and updates / creates a target record. In order for emails to get processed by unknown addresses, the Guest account with email address guest@example.com should always be present and active in the sys_user table. Even if the administrator creates a new account with user_name as Guest and email address as guest@example.com, this would not work. The default Guest user account must be active in the system if you want to allow unknown inbound email addresses.ResolutionEnable the default Guest user record and make sure Active = True and is not locked out. You can then reprocess the emails which were ignored, if necessary.Related LinksEmails being received-ignored with an unknown error string Reviewing emails getting ignored by inbound actions
