Outlook anywhere 2010 / 2013 / O365 hybrid RRS feed

  • Question

  • Hi All,

    I'm hoping one of the guru's here can clear up my confusion on outlook anywhere.

    We have an Exchange 2010 and 2013 environment, along with a Exchange online presence.

    We recently configured Exchange 2013 outlook anywhere and noticed it overwrote client settings (Outlook 2010) on all clients with mailboxes on 2010, 2013 and Exchange online. 

    From my understanding, we need to also have Outlook Anywhere configured in the exchange 2010 environment. If I set the OA configuration in 2010, will it overwrite the configuration on all clients that was set in exchange 2013?

    Thanks in advance.

  • Hi, I think Outlook Anywhere already enabled on your exchange 2010 servers before. Once you installed exchange 2013, configure autodiscover, owa, ews, ecp etc., and enabled outlook anywhere and changed DNS records pointing to new exchange 2013 servers (the VIP with your mentioned URL). Automatically all outlook will updated with new setting from autodiscover. And exchange 2013 will work as a 'proxy gateway' for exchange 2010 mailboxes.

    So no need to create another OA record, it will not work properly.

    Thanks

  • Even though Exchange 2013 can directly proxy the connection to exchange 2010 mailbox server but setting up the new VIP for exchange 2010 CAS server will not override any config setting for the users.

  • Hi vkarps,

    Agree with Prabodha & yspintu.

    There is an article detailed explains how various clients connect to an exchange 2010 coexist with exchange 2013 environment, it would help you a lot:

  • What do you mean by "overwrote client settings"?  Do you mean that Autodiscover configured the client with the settings you specified on the server?

  • yes, the Exchange 2013 settings were applied to users clients which had mailboxes within the Exchange 2010 environment.

  • I would say that's normal.

  • So what will happen when I configure Exchange 2010 Outlook anywhere to a different URL than the one specified in 2013?

  • Hello,

    If I understand then you have mixed Exchange environment (are you trying to upgrade your Exch from 2010 to 2013?). When you installed 2013, automatically the active directory forest is upgraded. It is perfectly fine to use exchange 2013 outlook anywhere for exchange 2010 mailboxes. 

    Are you facing any problem with outlook anywhere?

  • So we have mailboxes across 2010, 2013 and exchange online. The aim is to eventually move away from Exchange 2010, but that may take some time. 

    The aim is to allow users on Exchange 2010 to gain access to 2013 mailboxes and vice versa in the interim.

    The exchange 2013 OA is configured to a vip which points to the 2013 mailbox servers, ie. oa2013.company.com for both the internal and external url.

    I was planning to configure OA 2010 to a vip which points to the exchange 2010 mailbox servers oa2010.company.com

    However, I am a little concerned after seeing the configuration on clients change to oa2013.company.com even though their mailbox was on 2010. 

    Am I right in configuring OA on 2010 to that VIP? Will this break the OA configuration?
