Exchange admin create shared mailbox throwing error

[Don_Vlogeer]

Recently we observed couple of administrator with organization management role cannot shared mailbox. 

It will throw an error when creating shared mailbox and assign delegation as below. It basically means cannot find the OU from child domain, however the shared mailbox was not meant to be created on child domain. 

Strangely, this issue only happen to certain admin, not sure what permission was missing.

From the error, it seems like there is a problem with server configuration. From my research, the error message may occur if a wrong server has been specified for an operation that requires a specific server, such as Active Directory connectivity or role assignment. You may need to check your server settings and make sure they match the operation you are trying to perform. 

Kindly review this and probably upgrade the role assigned to the user and try again. Thank you!

After spending some time on digging and comparing the admin roles, server and so on, finally this issue comes to an end.

Ultimately it was because one of the exchange server domain controller using child DC as source. when shared mailbox created and attempt to grant full access or send as delegation it look for child domain instead of parent.

so we update all the exchange server currentconfigdomaincontroller to parent DC and issue never reproduce.
