I use cached exchange mode and my inbox is only 1.5GB why outlook increase OST size to 49GB. how can i fix it?

I Try another computer and have same problem with that account.

Hmm, thinking out loud here...

Have the admin DOUBLE CHECK the user quota.

If I recall, using the Exchange Management Console (EMC) one sets the limits in KB, or if using the Exchange Management Shell one uses MB to set the limits.

It is really EASY to be "off" by a few digits so "5GB" becomes "50GB" (where 50GB becomes a 49GB file on the local hard drive) especially if you think you're using MB when it should be KB.

Keep us posted!

user quota on server is true. i use GUI and set it in KB. on server side i think all is ok.

Server value in KB = 5242880

Can you confirm?
