Hi everyone, While trying to update a calendar item, one of my users received an error saying "The message store has reached its maximum size. To reduce the amount of data in this message store, select some items that you no longer need, permanently (shift + del) delete them." From the Exchange 2010 server side, the get-mailboxfolderstatistic cmdlet shows that the FolderSize of the "Versions" folder of his mailbox, which has the FolderType as RecoverableItemsVersions, is 29.9G. Could someone please give me a suggestion on how to fix this problem? Thanks in advance, Eric Z

Thank you Martina. I will schedule installing E2010 SP2 RU3. Thanks again, Eric
