I am running Outlook 2007 with exchange 2k7, I have only 1 user with this issue. When he opens outlook, he gets a error saying he's exceeded his mailbox size limit, and it gives him several different options. One is to look at local data/server data, archive, empty deleted etc. Only problem is, there is no store limit set up on his account or for his mailstore. Even with the exchange 2k7 default of 2gb, he's only at 1.6GB. As he is the only one experiencing this issue, i am baffled. Any help would be appreciated.
