WM5, Exchange meeting invites not sent

[Guest chucky.egg]

My device (Samsung SGH-I600) doesn't seem to be sending out meeting invites.

I don't know if it's a device issue, or an issue with my Exchange account.

Can anyone (pref with an Exchange account) confirm that their I600/Blackjack is sending meeting invites for me?

TIA

Just tried sending one direct from the Exchange system (using OWA) which came through, so I'm guessing it's the device.

I'm using Papyrus and Facade. (The built-in calendar doesn't seem to have an option for Attendees)

Tasks cant have Attendees, so I can't try them

Emails are still working

Anyone with an I600 have meeting invites working?

I tried from my old SP5 last night and that didn't work either, so this may be a Papyrus issue (the built-in calendar doesn't have that feature)
