I just installed the update again via Blackberry.com/update but still the same error.
I'm in progress at the moment to get more infos from rim about that problem. Because the issue consists if i use a device which is connected to an BDS 6.2 or if the device is connected directly to our Exchange Server via ActiveSync.
We also opened a ticket with Microsoft, but no response yet.

YES thats true it doesn´t matter if the blackberry is connected via native activesync or BDS 6.x.
But activesync works with a iOS device fine, so i think it is not an Microsoft/Exchange issue but i loved to hear the answer from the Microsoft-Support in this case

I have exactly the same problems with my Z10 devices and T-Mobile.
I then inserted a Vodafone SIM into the device and got the offer for an Update to 10.0.10.99 but the problem persists even with the newer firmware.

I just fixed the problem here!
Open Exchange Management console and go to Server configuration - Client Access. Highlight your Exchange server and edit the Active Sync properties below. Open tab "Authentication" and choose "ignore client certificates".
Immediately after this change I could send photos and attachments from my Z10 without any problem.
I hope this will fix it for you as well.

you right that fixed the issue :-)
But it is one big mess so now i have to choose:
if i want to send attachments from the BB or
authenticate via cert :-(
that´s really makes no fun anymore. In the moment BB 10 is not really Enterprise usable

It's not necessary a mess, It depends. We have our ActiveSync Server in the DMZ. On this one i wouldn't change the cert authentification. But with the BDS you can connect to your intern CAS Servers there i wouldn't have a problem to change the settings to ignore.

DSimmer's fix is good for Basic Authentication only. If certificate based authentication is required for microsoft exchagne activesync, you need to enable the option for "require client certificates". In this case, to make sure you can send, reply, or forward a large attachment from your BB10 device successfully, you need to increase the uploadReadAheadSize value in the IIS metabas on your exchange CAS server accordingly.
The command below shows how to set the uploadReadAheadSize value to 10MB:
appcmd.exe set config -section:system.webserver/serverruntime /uploadreadaheadsize: 10485760 /commit:apphost
