I'm using Novell Data Synchronizer Versie: 1.2.4 Build: 966. (just upgraded because of my problem, but the problem remained. Prev build: 730)

I have 10 iPhones. They work(ed) fine. Now I'm trying to get iPad's (with the same iOS 5.1.1) working with groupwise.

Just text messages work fine, but with an attached file the're not send. No error message, just "1 message not send". The message remains in the outbox with an exclamation mark!!

iPhones send messages fine.
