Exchange 2010 – EMC and EMS will not connect: FIXED


I have faced this problem twice now. Once on a new install which I was never able to fix and recently on an Exchange 2010 PS2 Rollup 4 uninstall.

Problem: Lost connectivity to the Exchange Management Console and the Exchange Management Shell

After uninstalling Microsoft Forefront Server Protection 2010 for Exchange Server I lost connect to the EMC and the EMS. After reviewing many Technet and Exchange forum fixes nothing worked.

Solution: Uninstall the Hub Transport role on the Exchange server.

After being unable to connect to do the troubleshooting I started to uninstall the Exchange server in pieces instead of trying to fix it. The main goal was to uninstall the Exchange 2010 server completely, upgrade the server hard drives and memory, and then reinstall new.

After uninstalling the Client Access role I was still unable to connect the EMC and the EMS. Next I uninstalled the Hub Transport role. Viola I was able to connect to the Exchange Management Console and the Exchange Management Shell. After reboot both EMC and EMS both still worked perfectly.

Something in the Hub Transport Role killed the Kerberos authentication for the Exchange Management Console and the Exchange Management Shell.

This worked for me hopefully it can help you out to. Obviously this may not be the fix for this problem for everyone but maybe it will help put you in the right direction for your needs.

Configure Message Delivery Restrictions on a resource mailbox in Exchange 2016

We just recently migrated from Exchange 2010 to 2016. In addition to our user mailboxes we also migrated a couple dozen conference room mailboxes or resource mailboxes as they are referred to in Exchange 2016. All our conference rooms are set to auto booking for everyone except on a particular conference room that is reserved for the executives. Only the executives and their administrative assistants are allowed to book meetings to this conference room. To limit the other employees for booking the executive conference room I used the Message Delivery Restrictions, Accept Messages From, Only Senders in the Following List option in Exchange 2010. I have eight people in the list. Since our move to Exchange 2016 we have had one executive leave the company, one executive admin leave the company, and one admin change responsibilities to cover for the one admin that left. I needed to make the changes to the Only Senders in the Following List option for the executive conference ro
