I'm part of a group that's just brought in 1,000s of messages from Yahoo. Trying to clean up some of the messages by adding tags and merging topics together.
I'm searching for topics I know are repeated and want to merge but the merge option isn't available from the drop down.
I've found it is available when I filter on a specific tag.
What's the best method for finding and merging a huge backlog of old messages?
