Hi I am trying to troubleshoot an issue whereby some messages on some of our users' Blackberry devices are not being deleted when they are deleted from Outlook. I came across this article here: http://www.port3101.org/featured-blackberry-kb-articles/202-kb04863-permanent-deletion-messages-outlook-do-not-reconcile-bb.html In it, it states: "Email messages selected for permanent deletion in Microsoft Outlook occasionally still appear on the BlackBerry smartphone after email message reconciliation has taken place. This can occur in any of the following situations: The Microsoft Exchange Server permanent delete notification queue has a fixed size. When the notification limit is exceeded, some permanent delete notifications may be lost. Microsoft Exchange will send only 20 to 25 notifications (on average) to the BlackBerry Enterprise Server when many email messages are permanently deleted at a time from the BlackBerry smartphone user's mailbox. Only 20 to 25 email messages will be deleted from the BlackBerry smartphone when hard delete reconciliation is enabled on the BlackBerry Enterprise Server. Note: Permanently deleted email messages cannot be detected by rescans. If the object deleted Messaging Application Programming Interface (MAPI) notification is lost, the email message is not deleted from the BlackBerry smartphone. There is no resolution currently available for this issue because it depends on the permanent delete notification queue limit for the Microsoft Exchange Server. As a workaround, BlackBerry smartphone users should avoid permanently deleting more than 25 email messages at once on their Microsoft Outlook accounts. " So basically, if a userr hard deletes, say, 50 messages from their Outlook at once, then BES may only catch the first 25 due to the notification limit, since Exchange will only notify BES of that first 25? What I am confused about is that, say the 50 were deleted using OWA or something. Then why is it that 'normal' MAPI clients such as Outlook do not suffer this problem and are always up to date, regardless of how many messages were hard deleted at once?

"Why" questions are difficult to answer. The answer could be that while Outlook is designed properly, BlackBerry is not in this case. It wouldn't be the first time. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." . "Pancamo" wrote in message news:a8861d10-0578-43ab-867c-cacbf08c88cd...
