  • Blackberry BIS with Mixed Exchange 2003 and Exchange 2010

    Hi guys,

    This is my situ;

    I have ex2003 with 100users on, we've bought ex2010 now to expand, both exchange boxes are on the network, blackberrys come in on adsl1 over ssl to connect to ex2003, this works fine.

    The only way i could get ex2010 to work with blackberrys at all is for them to come in on adsl2 over ssl, and for the gateway on ex2010 to be the internal ip of adsl2, but this isnt 100percent reliable, when emailing from a blackberry it sometimes says general failure and the email wont send.

    So my queries, what is the correct way of putting two exchange boxes on a network if users are split between the two? Do you recommend removing ex2003 completely? And any ideas why the outgoing blackberry emails connected to ex2010 say general failure!

    Hope ive explained it ok, Thanks!

    Blackberry - is that BES or BIS?
    If BIS, why aren't you using a BES/BES Express? BIS to Exchange is like owning a Ferrari and never taking it out of central London - completely pointless unless you just want to flash it about.
    If BES, which version?

    No problems with mixed versions and Blackberry, I have just completed a 1000+ migration where 60% of users were on BES. Came across fine, reactivated a handful of devices, which isn't unusual.

      Were using BIS, never looked into BES.

      So you would advise using BES, will this remove some of my unneccesary problems?

      I'm considering just removing ex2003 from the network completely and migrating all to ex2010, seems like the most sensible option instead of messing about with two boxes.

      Thanks,

        Whether you were having problems or not, I would still be recommending a move to BES Express. You can do that without any changes to the subscription the device is on. It will give you full functionality of the BES device, including two way sync.

        Your problems are exclusively related to using BIS. There are no issues with running two different versions of Exchange on the same network. If you want both sets of users to use OWA then you need two IP addresses and URLs, but that is all covered in the co-existence documentation on Technet.

        If it was me, I would use this as a good opportunity to move to BES Express and get the full functionality from your Blackberry devices.
