Mail Merge to email - can I send to Drafts folder in Outlook to edit BEFORE sending?

I setup a mail merge to Outlook thinking I'd be able to edit the messages before they sending, as I need to copy different info (from a list in Excel) to each one. But once I click the last OK, they're gone - no chance to edit. Is there some way to send the merged emails to the drafts folder so I can edit each one, then send? (I thought I'd ask just in case there actually is a way around direct email send)...

Thanks, I hadn't considered working offline... now that I have 20 individual emails setup, is there a way to edit those for the next mailing (minor changes to each) as a group, or do I really have to edit each email separately?? I suppose I'm just trying to find the best way to edit a group of emails (not exactly an Outlook whiz)... (Because I have different data from Excel in each email, I thought it would be easier to make the same edits to the body of each email, rather than re-merging, then having to individually copy the Excel data to each)
