Office 365 mailbox migration issue

Hello,

 

I try to migrate mailboxes from my Exchange 2010 to Office 365 / Exchange Online in a hybrid environment. For some mailboxes it fails with the following error message:

 

Error: MigrationPermanentException: The target mailbox doesn‎'t have an SMTP proxy matching 'domain.mail.onmicrosoft.com‎'.

 

From quick googling, "Automatically update e-mail addresses based on email address policy" checkbox is disabled for failing mailbox. So I enable the checkbox, but it does not solve the issue... migration still fails.

 

How can I fix it?

 

Any help much appreciated.

@Unisys,

 

Welcome back to the forums.

 

Just to note, this is not a Centrify-related question but an O365 migration question.

 

Did you try the guidance from Microsoft KB-2939340?  This came-up from searching the error message as the highest-relevant result:

https://support.microsoft.com/en-us/kb/2939340

 

More detail here:  https://blogs.technet.microsoft.com/rmilne/2015/08/20/office-365-mailbox-migration-target-mailbox-do...

 

Good luck!

Re: Office 365 mailbox migration issue

Hello Robertson,

 

Thanks for the tips. Yes, I have tried guidance from Microsoft KB-2939340. And it still does not work. My Email address policy looks fine, at least I can migrate new accounts to from our Exchange 2010 Exchange Online without problems. But it still not OK for accounts created before we switched to hybrid setup. I think that Centrify does not update some attributes for those old accounts... Is it possible?

 

I will try  to explain my logic with the following example. I have an old (pre-hybrid) account. "Automatically update e-mail addresses based on email address policy" checkbox is disabled for this account. We disable the checkbox for some accounts to have custom reply addresses in our single AD domain setup with multiple email domains. After switching to hybrid mode I updated email address policy (EAP) with additional SMTP address domain.mail.onmicrosoft.com‎. When I enable "Automatically update e-mail addresses based on EAP" checkbox I can see that the additional SMTP address (user@domain.mail.onmicrosoft.com‎) has been added. This works for the old pre-hybrid and for the new accounts. Here starts the difference. Migration to Exchnage Online works fine for the new accounts. And it fails for the old ones with the following error message: The target mailbox doesn‎'t have an SMTP proxy matching 'domain.mail.onmicrosoft.com‎'.

 

Another note: with almost any change I do for any AD account I get Centrify Directory synchronization report. But not for SMTP addresses attribute. Is it normal? 

 

Is it possible that Centrify does not update SMTP addresses for the old pre-hybrid accounts? How can I check if this attribute is updated on O365?

Re: Office 365 mailbox migration issue

I am not very familiar with the scenario you described.  My advice is to contact support or your customer success representative (if you're a paying customer), otherwise my coworkers are monitoring this thread and can chime-in/

Re: Office 365 mailbox migration issue

Hello Robertson,

 

Centrify does not synchronize SMTP addresses for the old pre-hybrid accounts automatically for me. Not sure if I configured something wrong.

 

Good news, I still can start sync for those attributes manually in Centrify Admin Portal – Users – select a user – Actions – Sync All Apps.

 

Now I have another issue. I usually go to Centrify Admin Portal – Roles – Office 365 – Members to add an AD user and provide O365 license. And usually that user appears on Users page of Centrify Admin Portal. But some of my AD users are not shown there so I cannot start sync manually.

 

How can I fix it? Any help would be really appreciated.

If you're having a new issue, my advice is that you start a new thread.  Other folks will be monitoring the board and chime-in.
