We have storage group which default size limit is 500 MB, we have created one new user on same SG and set size limit is 2 GB, in next day size limit showing 500 MB for that mailbox. How is it possible to revert default size limit whether we have set manually 2 GB size for mailbox? We have other user/mailbox which having 2 GB size limits, all are working fine.Dinesh S.

Where does it show that the limit is still 500 MB and which specific limit are you referring to?

it is for Mailbox Storage Limit.Dinesh S.

So the send and receive limit? Where does it show that its still set to 500MB?

This is for mailbox limits like Issue warning Prohibit Send Prohibit send and receive Default store size is 500 MB for all mailboxes, when I'm changing for single user mailbox size 2 GB manually after on maintenance it revert in 500 MB automatically, I checked all event on server did not found anything.

Hi Dinesh, Please refer to the following article to make the mailbox size limits take effect immediately and check whether the individual mailbox revert to the default size limit. http://technet.microsoft.com/en-us/library/bb684892(EXCHG.80).aspx I look forward to hearing from your update.
