Ok, we are sort of running out of space on one instance, and we noticed that
EmailMessage-s and their accompanying
Tasks take about 60% of our instance (we use a lot of Email2Case here). So the idea is to just offload old emails in closed cases to an external CSV and just remove it from instance. Since these are old completed tasks, the SF moved them from
Problems is that
ActivityHistory does not exist in the Export object list, neither in web interface nor in Data Loader utility. So how do I go about extracting that data (and subsequently deleting it from the said object).
I read this post (Trying To Export Activity History Object), however that doesn't seem to help, when I query Tasks for legacy entries, it returns zero rows, so the answer seems to be inaccurate.
