OK. so now I really am running beta 6. That was strange. Anyway Outlook working smoothly after upgrading this morning to latest version on the beta channel and MAC OS Monterey Beta 6.

See they want any additional logs from anyone else. Happy to shoot them whatever they want.

If you get a report crash page do so. At least they will know what is going on. They may not be aware of how serious this unless Apple is telling them.

They pulled that 16.53 update package.

Pulled th 16.53 from the link and now outlook doesn't crash but it just hangs with the spinning ball icon.
