I am using Windows Server 2003 SBS version. Since, my boss ask me this question, but I can't set the storage limitation more than 2097151KB. Anyone can help? Thanks.

well, if you don't want to put limitation on mailbox storage size for certain user , you can remove the option fromexchange general, under storage limists under user mailbox properties, where it says to use the default mailbox store default option, by this you will have unlimited mailbox size for this user. if you want to put a limit for certain user mailbox, then you have again to remove the check mark where it says "use default mailbox store ......" under teh storage limits tab, then specify the storage limits there, it should accept more than 2097151KB. please let me know if you need more help, and if my reply did help you in solving your problem.

This is true, you can't have the valua of the warning and prohibit send to be set the same value. you need to set a value lower than the prohibit limit by some migabytes inorder to notify the user that his mailbox will reached the maximum limit and that the user needs to free out some data from his mailbox. if you want to setup the maximum limit for that user to 2097152 , the you can set the following limit settings for that user: Issue a warning at (KB): 2097132 prohibit sent at (KB): 2097142 Prohibit send and recieve (KB): 2097152 by this your seetings will work, try it and let me know the result please. regards Alaa Al-Ankar
