The user is using outlook 2007 as the client and we have Exchange 2003 on the server. The user does not have any filters or spam settings different than anyone else(default). What might I look at or where should I start?I'm not an expert with Exchange Server so please be patient with me.Thanks all...-ct

Hi,Please check the email in OWA to see if it would be a outlook related issue or Exchange related issue.Please check if other users have full access permission on this mailbox How to Manually Grant Send As Permissions to a User with Full Mailbox Accesshttp://technet.microsoft.com/en-us/library/bb125118(EXCHG.65).aspx How to Give a User Full Access to Another User's Mailbox http://technet.microsoft.com/en-us/library/aa998707(EXCHG.65).aspxBesides,please check if you have any related rules have been created on Outlook.Regards,Xiu

Would it be possible for you to take a MFCMAPI session to the user mailbox & see if he has some hidden rules like re-directing mails to his .pst. Also can you run this command on the user desktop or laptop. Outlook/ CleanrulesMost probably taking a MFCMAPI session & looking for some hidden rules I hope so would solve the issue.RegardsKiran

Thanks for the reply guys, but neither of these things worked. and what's weird is that internal or external mail may come in to my mailbox on the server and then it will go away after a few minutes...and some emails never come in at all. it's intermittent and quite frustrating.

BUMP!still having these issues on my client only. I'm sure it's a server issue but i'm not sure where to look.the same still happens if i use the OWA client.a new meesage will come into the mailbox, i can see it and it will be there for about 2 minutes or so, and then disappear.if i goto Tools -> Recover Deleted Items, they all show up there.but why oh why would they e forced to be deleted from my mailbox on the server?please, any help is much appreciated.thanks to all....-ct
