Hi Eero,
Thanks for the reply, we did in fact install the Fix Pack 1 (as recommended by IBM on our support ticket) on 22nd May and the missing document issue was resolved. Not sure what the root cause was but it would appear that the default off-peak settings were over-riding the actual settings that had been applied in the server config document. We didn't get a chance to test that out as we applied the Fix Pack immediately before changing the config document..
We also had an issue around Japanese fonts not showing correctly when being sent to Internet Mail Providers (Gmail, Yahoo, iCloud...). Some characters were being displayed at a black diamond with a white ? in the middle. Was being displayed fine Notes to Notes and looking at the email code there were missing code characters once delivered to Gmail/Yahoo/iCloud.
Thanks
Paul.
