I was wondering if anyone had success with switching to the 64-bit version of Office after the latest Timeslips update. Notes show it's compatible now, however when we try to send out we get a Failure : Unknown Error using the MAPI64 email client.

Not sure if it's something on our end, or if it's a case where 64 bit Office wasn't actually supported yet. Update is relatively new so most things about 64-bit being not supported is (maybe) outdated.
