Ahh, thanks for the clarification! I've done precisely the steps detailed in this thread, but similar threads don't seem to be showing up for me
Thread Display Options > Show Similar Threads?
YES
Message Searching Options > Automatic Similar Thread Search
YES
Maintenance > Update Counters > Rebuild Similar Threads
DONE
But similar threads aren't being listed when I tab out of the Title field and into the message body field. Any ideas?
