Here is another one that got me… IBM Technotes to the rescue! (This one is IBM Technote #1414908 – Group Document Print and Print Preview only shows First Three Group Members):

Question
When you Print or Print Preview a Group document, the output only shows the first three member names in the members field

Steps to reproduce:

Open a Group Document, either in the Personal Address Book (Contacts) or in the Domino Directory. Ensure the Group Document Members field has more than 3 names. When you Print or Print Preview the document, the output only shows the first three member names in the members field. The field itself appears to be truncated in the print output.

Cause
New print functionality was introduced in 8.5.1. The user must now select “expand the name fields content when printing” in the print options before printing the group document.

Answer
This issue was reported to Lotus Notes Quality Engineering in SPR WTON7XAJ8N. It was determined that this is working as designed. New print functionality was introduced in 8.5.1. The user must now select “expand the name fields content when printing” in the print options before printing the group document.

I knew that would work for emails (the To: CC: and BCC: fields), but I never thought about the Members fields in group documents.

Hopefully this will help someone else…
