In addition to the new version being unusable, the older version is a dumpster fire as well. I came here to find a solution for export/import of calendars because that function is a joke on Mac. It restores to 'on my computer' (which leaves a heap of garbage on your Mac when you finish as a "bonus"), and there is apparently no way to merge it into the desired account so that it syncs with Outlook. I "get" that msft would love for everyone to use their products only, but that is NOT reality. Other companies who have both platforms and products develop their products the same across platforms. The answers on here are not helpful either... :-(
If only there were a regedit type hack tool for outlook.....teheeeheeee.
