Getting this error on multiple IOS (Iphone/ipad) devices. "This message has not been downloaded from the server". It doesn't effect every message, just randomly. Can be reproduced when messages are sent from one of our partners (nearly every message they send will cause this error on the Iphones). We are running Exchange 2010 SP2 Rollup 5v2.
This doesn't not appear to be an issue with spaces in the Exchange "accepted domains" that generally causes this issue, as we have none.
Anyone have suggestions for us?
Thanks
