Quick shoutout to this blog post by Tony (cached copy as I can’t access the original). The cmdlet has a -ContentFilter
switch where you can specify the date and other parameters by which you can filter out what is exported. Very irritatingly the date parameter expects to be in US format. And even if you specify it in US format to begin with, it converts it to US format again switching the date and month and complaining if it’s an incorrect date. Thanks to this blog post which explained this to me and this blog post for a super cool trick to work around this. Thank you all!
