Deleting on Blackberry not Synching in Outlook

In my current position I have to support Blackberry users. In my opinion, after having to support Palm OS and Windows Mobile, Blackberry has been the most stable. Now, it would be ridiculous to go so far as to say that Blackberry doesn't have any problems, because that just isn't so. Blackberry has plenty of problems. One of those problems has to do with the fact that by default, when you setup the Blackberry for use with a Blackberry Enterprise Server (BES), emails you delete on your hand held do not automatically delete in Outlook. Don't ask me why, it is just set that way. Seriously, why is water wet? It just is.

In order to make your deleted items sync when you delete them from your phone, you need to go into Messages > Options > Email reconciliation. Select the delete option and change the setting from hand held, to hand held & mailbox. Save the setting and you're set. If the setting is already set at hand held & mailbox, then change it to hand held, save the setting, then change it back and save the setting again.

90% of the time, this is what the issue is. There are a few other reasons, but this is what you should check first. Goodluck!
