I have a local AD account setup for myname.org. I created ONE user, with a UPN of me@myname.org.
I used the Azure Active Directory Connect tool, with default / express configuration.
This went soso. Despite making SURE that my AD SPN/UPN was setup correctly, i.e. me@myname.org, as well as MYNAME\me, in the Active Directory The AD Sync has created not one but FOUR accounts in Azure Active Directory that all seem to be 'me'.
I have a Member user type with the user name of me@myname.org ... this seems to be associated with my O365 account.
I have a Member user type with the user name of me.MI@myname.onmicrosoft.com ... no idea where this came from
I have a Member user type with the user name of me4200@myname.onmicrosoft.com ... no idea where this came from, nor the number 4200. It's not significant for anything. The source of this one says it's Windows Server AD; I think it incorrectly created this user instead of synchronizing with me@myname.org as it should have.
If this happens with my client, we will have a right disaster.
I have a Member user type with the user name of randomResourceMailbox@myname.org ... no idea where this came from. The "RandomResourceMailbox" was associated in O365 as "CTO@myconsultancy.com" and is a small resource mailbox with no user license, and no login. The name "CTO@myname.org" was created out of whole cloth.
The last two accounts were NEVER in Active Directory. One of them was in Office365 as randomresourcemailbox@anotherTLD.com as an additional resource mailbox only with no user license.
I NEVER had any duplicated accounts in AD nor in O365.
I elected not to use the alternative ID method as the point was to make this migration simple. Any ideas why me@myname.org and me@myname.org failed?
I found a synchronization error. It says my O365 account UPN is me@myname.org, and my AD Account is me4200@myname.org which is absolutely incorrect.
It then says my Proxy Address is wrong; the AD account is SMTP:me@myname.org but my Existing object (the O365 account) is an amalgamation of:
smtp:nickname@myname.org
smtp:me@myname.onmicrosoft.com;SMTP:me@myname.org
So, the UPN got modified by the AD sync tool incorrectly, and the O365 SMTP address is incorrectly parsed, as well as becoming a multiple value field for a proxy address (which is incorrect).
What's worse, is despite the fact that my UPN's were setup correctly, the tool decided to use a non-editable field called "Proxy Address" for the match, and made this be a multiple value field, which means I'd have to update my email addresses (part of Exchange administration) in my AD and keep them synced. That seems wrong.
How does this get fixed?
