Currently when the user receives the meeting invitation from an external domain (e.g.- Gmail) and when the user accepts that invitation from Notes Client, then a response with "Accepted" message is sent to the original sender of that meeting. Now when this Gmail sender checks the "Accepted" response, it shows the Notes user name like below.
e.g.- Testuser One/Acme has accepted this event.
Even using Calendar compatibility mode, this Notes user name is not stripped off.
This Notes user name is present in "Attendee" field of "ics" file. When we capture the ics file, we can see this name as well. There are no known methods to remove this Notes user name from "Attendee" field in "ics" file and even option to remove specific Notes item from MIME document cannot remove this particular name. If we try to remove this field then "ics" file would be broken and will not be recognized by external domains.
So there is a feature request to allow and option to fully remove this Notes user name from "Attendee" field in "ics" file, so that this name is never seen by external domain users in hierarchical format.
