Used Ports

Backup

The following table describes network ports that must be opened to ensure proper communication with the runtime coordination process deployed inside the Microsoft Exchange Server guest OS for application-aware processing during the backup.

From	To	Protocol	Port	Notes
Veeam backup server or Guest interaction proxy (in Enterprise and Enterprise Plus editions)	Exchange Server VM guest OS	TCP, UDP	135, 137-139, 445	Ports required to deploy the runtime coordination process on the VM guest OS.
TCP	6005-65535	Dynamic RPC port range used by the runtime coordination process deployed inside the VM guest OS for application-aware processing (when working over the network).* Note that Exchange 2010 and higher (in particular, Client Access) expands standard Windows dynamic RPD port range - this allows for better scalability.

Exchange Server VM guest OS

TCP, UDP

135, 137-139, 445

Ports required to deploy the runtime coordination process on the VM guest OS.

TCP

6005-65535

Dynamic RPC port range used by the runtime coordination process deployed inside the VM guest OS for application-aware processing (when working over the network).*

Note that Exchange 2010 and higher (in particular, Client Access) expands standard Windows dynamic RPD port range - this allows for better scalability. For more information, see https://technet.microsoft.com/en-us/library/ee332317(v=exchg.141).aspx.

Exchange Server VM guest OS

Veeam backup server or Guest interaction proxy (in Enterprise and Enterprise Plus editions)

TCP

6005-65535

Dynamic RPC port range used by the runtime coordination process deployed inside the VM guest OS for application-aware processing (when working over the network).*

Note that Exchange 2010 and higher (in particular, Client Access) expands standard Windows dynamic RPC port range - this allows for better scalability. For more information, see https://technet.microsoft.com/en-us/library/ee332317(v=exchg.141).aspx.

* - During the setup, Veeam Backup & Replication automatically creates a firewall rule for the runtime process. However, if you use firewall settings other than default ones, or if application-aware processing fails with the “RPC function call failed” error, you need to configure dynamic RPC ports manually.

Restore

The following table describes network ports that must be opened to ensure proper communication with Microsoft Exchange Server during application-item restore.
