Exchange 2013 Proxy Addresses RRS feed

  • Question

  • Hi,

    We have moved most of our users to Office365 and decomissioned our old Exchange 2007 system, however, the company wishes to have a small Exchange server in house for some other business email. Using an IIS relay has caused issues due to the load on it.

    As our users are in Office365 and have proxy addresses for mail.onmicrosoft.com in their AD attributes and as I am not totally familar with Exchange, my question is:

    Will installing Exchange 2013 again here in our company AD environment have any knock on affect on these proxy addresses or break anything for the users currently using Office365?

    Cheers,
    M

    So everything is managed in Office 365? No dirsync between you and the cloud?  

    By the way, if I just wanted a SMTP engine and didnt want IIS/SMTP, I would install an Edge Server instead of full blown Exchange. You can install Edge on the domain if needed and you can avoid any issues that may surface once you bring up Exchange. ( Autodiscovery comes to mind)

  • Hi,

    Since you decommission old Exchange 2007, every Exchange attribution has been cleared in AD.

    We need re-install Exchange server in On-premises AD, we might can recover a lost server by using the Setup /m:RecoverServer switch in Microsoft Exchange Server 2013. Then re-configure Hybrid environment Exchange 2013 with Office 365. For your reference: https://technet.microsoft.com/en-us/library/jj200581%28v=exchg.150%29.aspx

    Thanks

  • Hi Andy,

    I was somehow under the impression that I needed the whole thing in order to provide an SMTP relay etc outbound.  I guess not!

    Thanks for that, makes my job way easier.
