Another notice from the field support front.
If a user always send mails with a wrong sender name and all settings seems to be correct, look for a field in the sent mail called ‘$AltPrincipal’. If the wrong name is in this field create an action that corrects a field in the calendarprofile.
This issue is caused when the initial setup and configuration of the notes client was made with another users id file or the user has an ‘Alternate Name’. You may correct the owner of the mail file, but the ‘AltOwner’ field will not update.
