HiI have an issue whereby when mail in a public folder is read by one user it causes the same mail to become unread for other users, I have set 'Maintain per-user read and unread information'and all users are Owners.Exchange and server are at SP2.Thanks

Hi, First please understand that the state changes from Unread to Read only for the user who viewed the item. When you select this setting for a public folder, the items in the folder change from the Unread state to the Read state for each user when the items are viewed by the user. When another user views an item that has been viewed by other users, the item appears in the Unread state for that user. When the item is viewed by the user, the item changes to the Read state. Therefore, the Read or Unread state for items is maintained per user. The status is not maintained per public folder. When you clear Maintain per-user read and unread information for this folder check box, you must dismount the public folder store and then remount the public folder store for the change to be completed. More detail information for you: Description of the "Maintain per-user read and unread information" setting in Exchange Server 2003http://support.microsoft.com/kb/929396 If it is the case,then please feel free to let me know. Hope it helps. Xiu
