Problem with deploy Exchange hybrid

Question

Hello,

I have a problem with my Exchange 2013(CU 23) and deploying O365 Hybrid.

I have installed AADC on one of my servers and connected to the O365 tenant and synchronized the domain account with UPN which the same is my external domain.
The external domain is correctly added in O365.

To deploy hybrid I used domain admin with Organization Management role. From O365 I used an account with a global administrator role and include Business Premium Plan.

When I run HCW on my exchange I do this:

• On-Premises Exchange Server Organization - I choose "Detected the optimal Exchange server" and I selected "O365 Worldwide"
• In the next step, I sign in O365 account.
• In Hybrid Features, I select Minimal Hybrid Configuration and select Organization Configuration Transfer.
• In Hybrid Topology, I use exchange Classic Hybrid Topology.
• In the User Provisioning step, I used I will install AADC later.
• In the finishing step, I got an error: HCW8110 - Encountered errors while running organization configuration transfer.

Someone can help me?

From this article we can know that this error occurs if objects can't be copied over from on-premises to cloud.

Please verify you have the correct Management Role assigned to your account.

From this error message, we can know there lack of permissions for your account, so I would suggest you assign permissions below to this local AD account(Needed permission for Exchange on-premises administrator):

I also suggest you install AAD Connect before running HCW.

Do you really need to do the Organisation Transfer? I've done a dozen migrations in the last 18 months and never have I done an organisation transfer.

Answer 3

I had successful without Organisation Transfer.

Now I have a problem with migrating mailbox from exchange on-premise to O365.

When I try to migrate mailbox I've got error:

    User status 
    Data migrated:  
    Migration rate:  

    Last successful sync date:  

    Error: MigrationPermanentException: The target mailbox doesn‎'t have an SMTP proxy matching ‎'<tenant_domain>.mail.onmicrosoft.com‎'. --> The target mailbox doesn‎'t have an SMTP proxy matching <tenant_domain>.mail.onmicrosoft.com‎'. 

How to solve this?

Answer 4

The target mailbox doesn‎'t have an SMTP proxy matching <tenant_domain>.mail.onmicrosoft.com‎'.

Its telling you right there what to do.
You need to add an additional SMTP address to the mailbox of <user>@ <tenant_domain>.mail.onmicrosoft.com to the mailbox and let it sync with Azure before you can move the mailbox.
This will become the remote routing address of the remote mailbox once its moved to Exchange Online

Answer 5

Is the user>@ <tenant_domain>.mail.onmicrosoft.com proxy address synced to Azure as well? Is that it on the right side there?
