Error Synching Single User Mailbox

Question

Hello All,

We have setup our O365 in Hybrid mode so we can migrate our users at our own pace.  We have started to move users and all but 1 have synched and completed successfully.  This one user under the details of the migration job has the error below.  I tried moving the user to another DB on our On Prem but that option is no longer available.  I also notice that the icon in our On Prem Exchange has the green arrow indicating it's a synched mailbox although that has not happened.  Anyone have any tips on getting around this and getting our user migrated?  I've seen some articles mentioning blowing out their account on O365 and trying again after it synchs back up.  I opened up a case with support but thought i'd check here to see if maybe i could get it resolved.

Answer 1

Hi OCA,

As we communicated in the private message, you will try the following method provided by our service request engineer: delete the user from O365 and let it DirSynch back up and then try again.

Now, I'm writing to follow up on the previous post. If there are any updates on your side, please post back at your convenience.

Thanks,

Richard

Answer 2

Yes the re-synch worked.  I let it sit a day and it completed with no issue.

Answer 3

Hi OCA,

To better understand your situation, I would like to collect the following information:

1. Are there any difference of the problematic mailbox and others?
2. If you have hidden something from the error message, please provide the complete error message for further analysis?

Regarding “I opened up a case with support”, it seems that you have submitted a service request. Could you please provide the service request number so that we can check the details for you?

In order to protect your privacy, I’ve sent you a private message to collect the complete error message and the service request number. And you’ll see it by clicking Private messages under your details section in the upper-right corner.

Thanks,

Richard
