Column descriptions

For Outlook 2007 and Outlook 2010

The June 26, 2012, hotfix packages for Outlook 2007 and Outlook 2010 introduced several changes to the Exchange Server Connection Status dialog box. These include several new columns and the ability to resize the Connection Status dialog box. See the example in the following screen shot.

Microsoft Exchange Connection Status Screenshot

CID
Indicates the connection ID. This information is used together with Outlook troubleshooting log data to help Microsoft Support professionals diagnose connectivity problems.

SMTP Address
Because Outlook supports multiple Exchange accounts, this column indicates the account that is associated with a given connection.

Proxy Server
Indicates the proxy server through which Outlook connects. If you are connected to a server that is running Microsoft Exchange Server and that uses RPC over TCP (RPC/TCP), the proxy name does not appear. Only the RPC server appears under the Server name column (Server name column omitted from screen shot). 

Authn
Indicates the authentication type that a given Outlook connection uses. Possible values include:
ERROR
CLEAR (Outlook uses "clear" to indicate basic authentication — typically used together with SSL)
NTLM
NEGO
KERBEROS
ANONYMOUS
BEARER

Outlook can display multiple values in the Authn column if a connection is using multiple protocols. When this occurs, the values are separated by a space. The example screen shot show the following value:
Clear [Anonymous]

The image shows that the connection protocol column is RPC/HTTP. The Authn column shows that the RPC portion of this connection object is using anonymous authentication and that the HTTP portion is using Basic (Clear).

Note The Authn column alone does not fully define the security of an Outlook connection. The security of a connection must be verified by cross-referencing the Conn(connection) and Encrypt (encryption) columns. 

Encrypt
This column indicates the type of encryption used by a connection. Possible values include:
ERROR
NONE
SSL
NO
YES

Like the Authn column, the Encrypt column may contain information about multiple protocols. In that case, information about each protocol is separated by space. The example screen shot shows the following value:
SSL[No]

In the example screen shot, the connection protocol column value shows RPC/HTTP. The Encrypt column indicates that the HTTP portion of this connection object is encrypted by using SSL, and that the RPC portion has no encryption.

RPCPort
These values let you quickly determine the port on which Outlook is connecting and whether connection consolidation is working correctly.

Type
Indicates the Exchange endpoint for the connection. Values include mail, directory, GC (legacy), and public (public folder store).

Avg Resp
Shows the average round trip request or response time for client requests. This value includes server and connection latency. When you consider average response times, larger sample sizes give a truer indication of latency. For example, a large sample size could be 100 request/response pairs.
 

Avg Proc
Shows the average server processing time for client-side requests that are reported to Outlook by Exchange.

Sess type 
Specifies whether Outlook is connected to the Exchange mailbox in Cached Exchange Mode or online mode. This information is useful when you troubleshoot latency issues. Possible values include Forground, Background, Spooler, and Cache.

Interface
Shows the local network card that is used by a given Outlook connection.

Conn
Describes the connection protocol binding that is used by a given connection. Values include HTTP, RPC, and TCP.

Version
Lists the Exchange Server version for a given connection.
 

For Outlook 2013 and Outlook 2016

Outlook 2013 and Outlook 2016 support Modern Authentication. Modern Authentication uses Azure Active Directory Authentication Library (ADAL). By default, Outlook 2016 is enabled for Modern Authentication. Modern Authentication can be enabled for Outlook 2013. For more information about Modern Authentication, see Updated Office 365 modern authentication.

CID
Indicates the connection ID. This information is used in together with Outlook troubleshooting log data to help Microsoft support professionals diagnose connectivity problems.

SMTP Address
Because Outlook supports multiple Exchange accounts, this column indicates the account that is associated with a given connection.

Display name
Contains the name of the message store as displayed in the Outlook Navigation Pane and Folder List.

Proxy Server
Indicates the proxy server through which Outlook connects. If you are connected to a server that is running Exchange Server and that uses RPC over TCP (RPC/TCP), the proxy name does not appear. Only the RPC server appears under the Server name column (Server name column omitted from screen shot). 

Server name
Specifies the actual URL that is used to connect to the resource.

Status
Use this column to determine the current status of the connection to the Exchange Server resource.

Protocol
Specifies the protocol that is used for the connection.

Authn
Indicates the authentication type that a given Outlook connection uses. Possible values include:

ERROR
CLEAR - (Outlook uses "clear" to indicate basic authentication — typically used together with SSL)
NTLM
NEGO
KERBEROS
ANONYMOUS

Req/Fail
Lists the number of requests that are made during the session and the number of those requests that failed for the specific connection.

Avg Resp
