What is email reconciliation?

Email reconciliation is used to configure email deletion handling option of email accounts that are set in BB device.
For each mail account you can state whether you want the e-mail deleted on the handheld or the mailbox and handheld;
You can set the device the following ways:
Enable or disable wireless reconciliation and configure how conflicts are handled.

In order to set reconciling options on Black Berry Device go to:

Messages –> then select “Options”–> “Email Reconciliation”

Reconciliation options are:

Delete on: “Mailbox & handheld” – Means: When you delete message on Device or outlook message will be deleted.
Delete on: “Handled” – Means: When you delete message on Device, message won’t be deleted from mailbox.
Recommended settings setup:

1. From your home screen, go into your Messages folder.
2. Once in your messages, folder, bring up your menu
3. Scroll down to and choose “Options”.
4. Scroll down to and select “Email Reconciliation”.
5. In the “Email Reconciliation” menu, make sure “Delete On” is set to “Mailbox & Handheld”.

8. Save your changes.
9. Exit back out to your messages folder, and once again bring up the menu.

11. Your messages should now synchronize between your BlackBerry and In-Box.
Some general guidelines for Reconciliation

Most people thing that message deleted on outlook should disappear from BB device immediately and start panic. So don’t , be more patient . it takes approximately 20 minutes till messages are deleted from Handheld

1. If you delete an email from Outlook you need to leave it in the recycle bin otherwise the BES will lose track of the email and it won’t be deleted from the device. Don’t use (Shift+Delete) If you want to use shift+delete you need to activate Hard deletes reconciliation on BES 5 Server.
2.If you Outlook account is set up to transfer new emails to PST . They will never get to your BB device.
3. Remember! The deletes from Exchange to BlackBerry is not immediate. BES reconcile uses the 20/100 rule. That’s every 20 minutes or 100 changes whichever comes first. Alternatively, you can use the Reconsile Now function. Outlook in cached mode only does send and receive every 5 minutes (this also updates read, deleted & moved items), then the device will only do reconciliations every 15 minutes. To speed this process up just hit “Send & Receive” and then “Reconcile Now” on the device.

Testing:
Outlook to  BB takes up to 20 min. I find it useful to do this test:
Delete – BB
Delete – Outlook

Wait for them to deliver to both mailbox and BB.
Now delete – BB on Blackberry and watch outlook, it should take a min or two. And move to deleted in Outlook
If that works… It’s working as it should and you’re dealing with a user workflow issue. I find it helpful to turn off Empty delete folder on exit.
