Answer 1

Hi  Ashraf
Thank you for your question.
Exchange update cannot continue because the computer that is running update is not in the same Active Directory site or domain as the server that is assigned the domain schema master role, also known as flexible single master operations or FSMO.
You can refer to the following link to change exchange site schema:
http://technet.microsoft.com/en-US/us-cn/zh-hans-cn/library/2376fec1-b9ce-44db-beb6-cb9ac4788988.aspx
You also notice the order for updated:
1.Client Access servers (beginning with the internet-facing site)
2.Hub Transport and Edge Transport servers
3.Mailbox servers
4.Unified Messaging servers
You can refer to the following link to update:

If there are any questions, please let me know.
Best Regard,
Jim
