[horde] Can't synchronize older devices with ActiveSync-2.13.2

[Michael J Rubinsky]

Quoting Arjen de Korte <arjen+horde at de-korte.org>:

> I have several (older) devices that stop synchronizing with the  
> latest (2.13.2) version of Horde_ActiveSync. Calendar  
> synchronization has been broken for most of them (and the newer ones  
> too) for quite a while already (see Bug #13022), but now also  
> mailboxes are affected. Some mailboxes will synchronize fine, but  
> others (it seems to be the ones with lots of messages in them)  
> don't. Removing accounts and provisioning devices again doesn't help.
>
> One thing that I noticed is, that now all devices report the same  
> 'Supporting protocol version':
>

> Supporting protocol version: 14,1, Using Horde_ActiveSync v2.13.2

Can you provide the exact string that the client sends in the version header?
