InBox and auto refresh/new mail

Am having a problem with a user’s inbox.I have tried all sorts of things and nothing seems to work, I have searched this and other forums and have not found a solution. New mail arriving into an inbox is not showing up. The user is forced to click on the refresh button before anything will show in the inbox. User Preferences are set to check for new mail every 5 minutes. This particular user is the only one experiencing this problem. I have seen posts in which others have had this problem but did not see what the solution is.

Can anyone elaborate on this?

Subject: Find the following couple of lines in the Notes.ini file

and delete them:NewMailSeqNum=55694

NewMailSeqNum052562FB:0081888D=55694

the second line will be different for your mailfile’s replica id.
