Problems Exchange 2013 ActiveSync + Android Client

Hello,

I'm with an access problem by using ActiveSync on Android.

I have a migration environment \ coexistence Exchange 2010 and 2013;

When I use the Outlook app on android access works perfectly when using any other client in android access does not.

I'm using a client called MailWize that works perfectly when my mailbox is hosted on the exchange in 2010, but the exchange in 2013 does not.

Has anyone had a similar experience?

Thanks
