I recently installed Exchange Server 2010 R2. Two of my Blackberry users (who connect via IMAP) say that their messages from other email server arrive promptly, but that there is a delay of up to 15 minutes receiving email from our Exchange Server. What settings or configuration changes might there be that I may make to help this issue? ANY help will be greatly appreciated.Doug Pruiett Good News Jail & Prison Ministry Richmond, Virginia www.goodnewsjail.org

Is there a reason they are not using OWA to setup the BlackBerries? Using OWA would be the preferred method.

THanks for responding. The main reason may be because we used IMAP under Exchange 2003. Can you direct me to instructions on how to setup the Blackberry using OWA? And to help me understand, when you say OWA (Outlook Web Access), I think of the web site interface folks can use to access their email via an internet browser. So it appears that OWA has a broader meaning?Doug Pruiett Good News Jail & Prison Ministry Richmond, Virginia www.goodnewsjail.org

BIS Email Setup I would also recommend not using IMAP if possible.

Okay. The user changed to OWA. Still complains that messages are delayed 15+ minutes from being sent (from a user within our domain). Is there anywhere in Exchange Management Console where I can tweek a setting that may affect this?Doug Pruiett Good News Jail & Prison Ministry Richmond, Virginia www.goodnewsjail.org

Hi What you need to have a look at are the message tracking logs to see if they confirm what the user is seeing. http://technet.microsoft.com/en-us/library/bb124926.aspx Steve

You could try implementing Message Tracking to see if there are any delays showing up on the Exchange Serve. http://technet.microsoft.com/en-us/library/aa997984.aspx Also, could you open OWA as him (from browser) and send an email to see if it gets delayed as he's saying? Wondering if it's an issue with the phone not picking things up properly as opposed to the mail not getting delivered. Don't be offended by this question but have you checked there's not a 'check for email every 15 minutes' setting somewhere on the BlackBerry? :p

And to help me understand, when you say OWA (Outlook Web Access), I think of the web site interface folks can use to access their email via an internet browser. So it appears that OWA has a broader meaning? That is essentially what OWA is. BIS uses the OWA credentials to connect to the Exchange server and send/receive new messages.

This is how BIS checks for emails. Now if they use Yahoo or Gmail it is generally instant. BIS checks the account when it is set up. BIS doesnt find email. BIS checks back in 15 minutes. BIS finds email. BIS compresses and sends email to the handheld. (first 2kb of the email) BIS checks back for mail in 3 minutes. BIS doesnt find mail. BIS checks back for mail in 3 minutes.

If they want instant mail delivery you will need to setup a BES/BES Express.

DJBoots is correct, BIS does doesn't work on direct push real time but based on periodic polling based on the intervals the poster described.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Thanks for the reply. What does BIS stand for? How can I or the user setup BES/BES Express on their Blackberry? What does BES stand for?Doug Pruiett Good News Jail & Prison Ministry Richmond, Virginia www.goodnewsjail.org

BIS=Blackberry Internet Service BES=Blackberry Enterprise Server To use BES you will need to install a server in your environment for this purpose. http://us.blackberry.com/business/software/besx/
