Is it possible to export posts and replies for the last year? I need to be able to provide this information to my management team to evaluate. I did research this question but only found the option for the description.
There isn't an easy way to do this at this time when it comes to the replies.
What you could do is filter in conversation management by topics posted within the past 12 months which would show the topics created in the past 12 months. You can then export that view.
For the replies, filtering by topics with the last activity date in the past 12 months and then exporting that view is going to be your best bet. That will pull in the entire conversation and not just the replies though, so it may be more than what you need but would also give context for the replies.
