Hello Everybody. Does anybody know which is the biggest size a mailbox in a Exchange Server 5.5 can support? I mean, a user in my company has 3Gb in his mailbox. He doesnt use pst files. I know pst files can support about 2Gbs or 16000 messages. I am a little affraid his mailbox or the entire priv.edb can be corrupted soon. If someone knows some anything or an article about it, please let me know. Thank You all !! Deniz
