Weve recently built an Exchange Server 2007. My boss occasionally gets an error saying the administrator has limited the amount of messages open simultaneously ( I apologize for not having the exact wording, he closed it out before I could get there to see it. Once this occurs he cant open any more messages and has to restart Outlook. ( He is running Outlook 2007). I was wondering if Im just missing something easy here but havent found any answers by goggling it. Thank you for your help. Sean
