Publishing 2 versions of exchange in one UAG trunk? RRS feed

  • Question

  • Is there anything special that needs to be done to publish two version of Exchange services (OWA, outlook anywhere, activesync) from the same trunk? If both 2007 and 2010 were to be published I would assume you would just use the one IP address for the trunk then make sure you used different public host names for them for example:

    exchange2007.example.com

    exchange2010.example.com

    Is there any reason publishing both from the same trunk wouldn't work? If it doesn't I would assume that plan B would be to publish them in separate trunks and publish any other apps in just one of the trunks then configure the trunks for cross-site SSO as described there:

    Implementing cross-site single sign-on

    So any reason why Plan A of publishing them both in one trunk might not work? - Thanks

  • Hello,

    UAG at this time only support publishing 1 version of Exchange (OWA,Outlook Anywhere and ActiveSync) on one trunk.  You can have a different version of OWA only, but not Anywhere and Active Sync.

    I think it would be best in the long run to just build another trunk for different versions of exchange.  

    I'm guessing you have limited public IP addresses... but I cant think of any other clean workarounds.

    Regards

    Dennis

  • Are you looking for a co-existence solution whilst you run both versions?

  • Yes running both versions as some areas migrate. Both 2007 and 2010 are expected to be running for some time.

  • Ok, this is a little more complicated.

    I would suggest you look at the following document to understand the publishing needs:

    http://msexchangeteam.com/archive/2009/11/20/453272.aspx

    I've seen some good information on co-existence using ISA/TMG, but nothing for IAG/UAG. I guessing you could emulate the approach used for ISA by using two UAG trunks, but I have not had to do this for real yet.

    Does that help?

    Cheers

  • In teh main trunk publish ex2010 and publish a link to another trunk.   These 2 apps in the main trunk I suspect you may use authorization on so a user sees the appropriate one.   The i'd use cross trunk sso and publish ex2007 in a second trunk.   For outlook and activesync, its really the same whether its in same trunk or not.   For OWA, it will feel pretty much the same for the user, even though technically they will go thru the UAG session validation process when going to owa2007, but the cross trunk sso will ensure no need to log in twice.

    The other possible option is do ex2010 on main trunk, as well as owa 2007 on main trunk.   Then on a second trunk do activesync2007 and outlookanywhere2007.   In this case you won't even need the cross trunk sso.  The downside is the users need a different url for owa2007, then for AS2007 and OA2007.  Though maybe not a ig deal as most users probably would get to OWA2007 by going to the main trunk url, and clicking the owa2007 link..

    Thanks,

    Mark
