Microsoft Exchange Critical Error: Requested Value 'TeamMailbox' was not found.

Hi MS Community,<o:p></o:p>

Did any one have experienced this error and found a solution?<o:p></o:p>

Background:<o:p></o:p>

We have successfully deployed (I think) a Office 365 hybrid configuration, we can migrate users from on-premise to cloud O365 and back.but, every time we opened the EMC on our Exchange 2010 upgraded to SP 3, this error message pops out.<o:p></o:p>

<o:p></o:p>

this happens when we open the EMC >> Microsoft Exchange >> O365 >>Recipient configuration.<o:p></o:p>

hope somebody can help us.<o:p></o:p>

Thanks.<o:p></o:p>
