Mail flag - FollowUpStatus field problem

I want to set mail flag using lotusscript. But setting FollowUpStatus in script doesn’t show in the mail fields. The item is not saved or something like that. Any idea why, any solution? Thanks

doc.FollowUpStatus = “2” ’ no effect, not set

doc.FollowUpDate = “”

doc.FollowUpRemoveFromInbox = “”

doc.FollowUpText = “”

doc.FollowUpTime = “”

Call doc.Send(False)

Subject: Follow Up flag

The router removes all Follow up flag data from an email when it is mailed. Follow Up flags are specifically for the saved message (for reference by the sender only).

When Follow Up feature was implemented back in R6, customers did not want email recipients to see what kind of follow up (or follow up text) might have been set on emails they sent.
