Not sure how to do that across mutiple worksheets, but you could consolidate
just the email addresses from each sheet into a separate workbook, then run a
pivot table on the address, which would give you a list of uniques, and a
count of how many functions were associated with each.

Copy and paste as values the result list of addresses

Hi all,

I'm looking to count unique email addresses across several worksheets. All
email address are in field E in each worksheet. I'm trying to avoid
consolidating all records onto one worksheets. Your help is very appreciated
here!

BTW: Each worksheet represents an event where attendees provided their email
address - some users attended multiple events. I'm trying to get an overall
unique count of attendees.
