Highly Available Exchange Email is a necessity for any business. For this customer, it's something they can't do without for more than several minutes. Office 365 Migration Migrate from our old SMTP provider to Office 365 TECHNOLOGY IN THIS DISCUSSION Join the Community! Creating your account only takes a few minutes. Join Now I migrated our Exchange 2010 to Exchange 2013 over the weekend. Running on Server 2012 Standard. Everything worked fine on Sunday - (mailflow, owa, etc...). On Monday morning we stopped receiving outside emails. I restarted the MS Transport service and that fixed it temporarily (bunch of emails bursted in). After that the mailflow stopped. I started troubleshooting via telnet and I am getting 421 4.3.2 Service Not Available message 1. transport service is up 2. all exchange components are in active state 3. Connector for anonymous connections and outside relay is enabled and the local subnet from which I am connecting to the server is defined in the scope 4. I am getting the same error message even when connecting locally from the server itself 5. Installed SP1. That did not fix the issue 6. I binded all connectors to the local IP address (instead of 'all available ipv4'....) 7. Restarted transport service multiple times 8. Restarted the server multiple times 9. Disabled anti-malware scanning I am desperate. Please advise. I have a good backup of old Exchange 2010 server. Does anyone have experience of moving back to Exchange 2010 from 2013? Thanks!

upgraded an Exchange 2013 cluster node from Exchange 2013 CU7 to Exchange 2010 CU10. After the upgrade, emails failed to http://clintboessen.blogspot.com/2015/10/exchange-2013-421-432-service-not-active.html come in on the cluster node with the following SMTP error being generated "421 4.3.2 Service not active". This can be reproduced by simply telneting the faulty Exchange 2013 server. After entering MAIL FROM: into the SMTP syntax, the error occurs and is shown numerous times throughout the receive connector protocol logs on the frontend transport stack. After further error 421 investigation I found out that majority of the Server Components for the faulty Exchange Server were in an inactive state. To bring the server back to an active state, ServerWideOffline was set to Active which resumes all services using a requester of Maintenance. This was done with the following command: Set-ServerComponentState -State Active -Requester Maintenance -Identity AB-EXCH-02 -Component error 421 4.3.2 ServerWideOffline Note: ForwardSyncDaemon and ProvisioningRps is Inactive by default. After running this command all Exchange 2013 components were back to an active state apart from components disabled by default.
