Subject: [MSUNAG] Exporting Old Exchange Mail for a Mac User without MS Office?

Hi everyone,

One of our users is retiring. Of course over the years, she has accumulated a rather sizeable PST of Exchange email. At home, she currently has a Mac, but I don’t believe she owns a copy of MS Office. I’m looking to export her email into some sort of usable format, preferably organized with the same folder structure as her PST. Any ideas as to the best way to go about this?

Thanks,
