Default HELP - Bes V4 with exchange 2003

Please Login to Remove!

Hello to everyone newbie here

Yesterday I set up a Bes server v4 running alongside MS exchange 2003. I configured the devices yesterday and they were then turned off over night ready to be given out today.

During the day numerous emails have been and as the devices have been turned off they sat in the pending queue on the BES Server once the devices were powered on the emails were fired down, great all working fine.

However people are now complaining that there are numerous emails that have been sent down onto there blackberry devices that they have deleted from the outlook mailbox's. Is this because the devices were turned off hence the mails have just sat in the pending queue and have been fired down straight away or as they have been deleted shouldn't they have been sent to the blackberry's.

When the devices are turned on should the mailbox and the blackberry be a sync ie an old email is deleted from the mailbox and it is also removed from the blackberry and they same the other way. Also is there a delay time between the mail hitting the outlook mailbox and been fired out to the blackberry via the bes server ie time for the user to delete the email.

Also is any of the above effected by the setting that are set on the device

Many thanks in advance if anyone can answer any of my questions

Look at this as wireless redirection as one step (to the BlackBerry infrastructure) and then wireless reconciliation as another step (the delivery to the handheld and status synchronization - read/unread/deleted).

Now, for an email to have the status reconciliation, it has to have the email on the Exchange mailbox (on the server) in order for it to have a source to base the handheld message status on - i.e., if the item is to be removed from the handheld, then the email will have to be present in the Deleted Items on the server for that user; if the item is marked as read, then it needs to be present in the user's Inbox on the server.

As far as I know, once a message is sent to the BlackBerry infrastructure for delivery to the handheld, it is there in pending status until it reaches the handheld or times out on the network (I believe this is 4-7 days or something like that). Once it reaches the handheld, it will then query the user's mailbox for the status update (mark it as read, leave it alone, delete it) ... if it has nothing to query as a source, then it simply leaves it alone (BES 4.1 will allow you to take this into account and have the messages removed if not source is found, aka "hard" delete support).

It's a good idea to have users remember this if they 1) are hardcore deleters who empty their Deleted Items ever minute or two, 2) have a secretary who manages their mailbox for them (there will be no source if they delete the item, so they'll need to move the message to the user's Deleted Items), 3) use a PST/Archive file for an ending point for messages, etc.

I believe the message is first 'redirected' (copied) by the BES service account from the user's mailbox to the BlackBerry infrastructure (where it then sits in the Pending status), and then is delivered from the infrastructure to the user's handheld over their carrier's APN (I believe that's correct - there are workflow diagrams within the Administration Guide that will have a definitive answer on that). Obviously, if its sitting out in the BlackBerry infrastructure, then there is nothing to update a status on.

Hope that helps.
