We’re noticing a problem caused with the local outlook 2010 client being used in conjunction with the archiving client.  If you have a quota assigned on the exchange server.  From a client side it will add the total used space from the archive & your inbox together – this means you may have only have used 50% of your exchange quota – but the client starts behaving as if the total quota has been used.

Result :  we have to set our quota limits in Exchange to a factor of what we really are using

Anyone is facing this issue as well?

We are using S1 6.7 sp2
