@Command([OpenCalendar];name)

We have a button that is designed to open the calendar of the notes user whose name is selected. It uses @Command([OpenCalendar];NAME). Some users intermittently receive a message “Cannot open the calendar for NAME”. If that person’s calendar is opened directly and then the button is tried again it works. The problem always goes away after awhile. The problem usually occurs shortly after they first log into Lotus Notes. Any ideas on the cause of this?

What is the format of the NAME?

Also, is this a field on the document or computed by a formula within the button.
