I didn't understand the "Print Output Document" from a previous post and
liked what I saw on the preview screen in step 6 so was having the same
problem. I found that I misunderstood the last step which is "Edit
Individual Labels." It is only at this point that Word actually completes
the merge and you can see all the pages and a completed document. You must
complete either a print or edit to see the complete merge.

Can see only one page of 30 labels in preview
Can click over to additional labels past recipent 30 in "Preview your labels"
When I click on "Edit Recipient list" I see in "Mail Merge Recipients" all 900 name/addresses.
Please Help!
