One of my clients is switching from iphones to BB Z10 and i'm having an issue with emails. I'm not using BES due to the fact that they are sharing many accounts with exchange. I may have to start using it tho if there is no fix.
Emails work fine but for some reason the Z10 aren't capable of sending attachments through exchange. Emails with attachments fail to send. I'm using the built in exchange connector.
In the Exchange EMC go to CAS active sync settings. Then "Authentication" tab. Then ensure "Ignore client certificates" is selected. Also I deleted all old expired unused certificates.
