Remove On Premises exchange Hybrid and go fully Online

Hello,   I currently have a scenario where there is a Hybrid Exchange environment with 1 server. All my mailboxes have been migrated online.   I would like to completely remove dependency on ...

I'm sorry - still not seeing it.  It says "not recommended" - can you explain the part where it is actually "required"? 

 

Or more importantly - are you saying that I cannot change the email address for a user from Active Directory console or add an alias (which I can)?  Or update their manager, or address, or title? (Which I can)

 

I'm trying to find someone from Pernille-Eskebo.com that says it's not supported.  But everything I read, its a MVP or someone not from the company saying it's a requirement.  Should be easy to find in official documents no?   Alas - there is nothing about it in AD Connect pre-requisites, and Microsoft only says its required "during hybrid" but I have yet to see an actual document state its required even after your hybrid deployment is complete.

 

Happy to be wrong - I just haven't seen it yet -

Hey Joe,

 

Question of whether it is supported or not aside, I was wondering how you are managing things like adding an alias, etc?  I have always done this through the EAC in our environment.  The last time I think I saw the ability to modify Exchange attributes through AD Users and Computers was back with Exchange 2003.  Am I missing something, or are you using ADSIEdit?  Thanks!

    As Spiros says - we simply use AD Users and Computers to edit our Exchange properties for O365

      Joe Wichowski Are you uninstalling Exchange from these environments, or ghosting it? In our experience, when Exchange is uninstalled (single server environments); attribute values (such as proxyAddresses) were removed. We had to manually add the proxyAddresses back in.

        In our case ProxyAddress stayed intact. Exchange was uninstalled, but it had to be decommissioned first and it was in hybrid more before that. It was done by our partners, so i'm not sure which step makes it keep the scheme and fields.

    Hello Steve,

     

    you can modify Exchange attributes / settings over Active Directory Users and Computers (ADUC) console. Open ADUC, hit View, Advanced Features, select a user and change to Attributes tab. Here you could change the mail alias by changing the mailNickname attribute.

     

    For the changes to be reflected in your O365 Tenant please wait or force the next Azure AD Connect sync.

     

    Kind regards

    Spiros
