Fortimail 6.2.5 FM200d Server Mode increase Domain Disk Quota not working

Hi:

I select a Domain and User Domain then select a Domain 

Edit Other      Service Settings +          and I Enable Domain Level Service Settings

and change Max user Quota from 1000 to 1500 and I also tried 2000

It accepts this and if you edit again it is there.

When I then go to  Domain User the user still shows 90% 900MB of 1000 but should now be 900MB of 1.5GB 60%

The quota does not reflect on the user account. I even rebooted the FM200d but it has no effect - the quota stays at 90%.

Is there any work around for this - I do not see anywhere else where the storage can be defined.

My mailbox disk shows 743Gb free.  Log disk is 181Gb Free

Thanks,

Scott
