Attributes

Attribute

Action

Req/Opt

Default

Description

action

all

Required

The action to take. Must be one of the following values:

  • open: Open a new persistent named connection

  • close: Close a named connection

  • getSubfolders: Get information about the subfolders of a specific folder.

connection

all

Required for open and close actions

The name of the connection. You can specify this ID in any tag that you use with the open connection.

ExchangeApplicationName

open

getSubfolders

Optional

exchange

The name of the Exchange application to use in the URL that accesses the server. Specify this attribute if your IIS server does not use the default name for your Exchange application.

ExchangeServerLanguage

open

getSubfolders

Optional

english

The language of the Exchange server. If you are not sure, you can specify the empty string. For all values except english, including the empty string, the tag tries to get folder names from the server in the client’s local language. In some cases, such as when there is a large amount of data on the server, it might take significant time to get folder names from Exchange server in the local language.

folder

getSubfolders

Optional

The root of the mailbox

The forward slash (/) delimited path from the root of the mailbox to the folder for which to get subfolders.

If a folder name contains a forward slash, use the _xF8FF_ escape sequence to specify the character in the name.

formBasedAuthentication

open

getSubfolders

Optional

no

A Boolean value that specifies whether to display a login form and use form based authentication when making the connection. If the attribute value is no (the default), and the Exchange server returns a 440 error status when ColdFusion tries to connect, ColdFusion displays the login form and attempts to use form based authentication. Therefore, you can safely omit this attribute if you do not know if the server requires form based authentication.

formBasedAuthenticationURL

open

getSubfolders

Optional

The URL to which to post the user ID and password when an Exchange server uses form-based authentication. Use this attribute only if your Exchange server does not use default URL for form-based authentication. The default URL has the form https://exchangeServer/exchweb/bin/auth/owaauth.dll, for example, https://exchange.mycompany.com/exchweb/bin/auth/owaauth.dll.

mailboxName

open

getSubfolders

Optional

The ID of the Exchange mailbox to use. Specify this attribute to access a mailbox whose owner has delegated access rights to the account specified in the username attribute.

name

getSubfolders

Required

The name of the ColdFusion query variable that contains information about the subfolders.

password

open

getSubfolders

Optional

The user’s password for accessing the Exchange server.

port

open

getSubfolders

Optional

80

The port the server listens to, most commonly port 80.

protocol

open

getSubfolders

Optional

http

The protocol to use for the connection. Valid values are http and https.

proxyHost

open

getSubfolders

Optional

The URL or IP address of a proxy host, if necessary for access to the network.

proxyPort

open

getSubfolders

Optional

The port on the proxy server to connect to, most commonly port 80.

recurse

getSubfolders

Optional

false

A Boolean value:

  • true: get information on the immediate subfolders of the specified folder only.

  • false: get information on all levels of subfolders of the specified folder.

server

open

getSubfolders

Required

The IP address or URL of the server that is providing access to Exchange.

username

open

getSubfolders

Required

The Exchange user ID.

Note: If you specify the getSubfolders action, you can specify the attributes that are listed as working for both the open and getSubfolders actions only if you do not specify a connection attribute.

Usage

The cfexchangeconnection tag can open or close a persistent connection with an Exchange server. If you use the cfexchangeconnection to open a connection before you use any cfexchangecalendar, cfexchangecontact, cfexchangemail, or cfexchangetask tags, you can use multiple tags to interact with the Exchange server without incurring the overhead of creating a connection for each tag.

Note: To establish any connection, the Exchange server must grant you Outlook Web Access. For information on how to enable this access, see Enabling access to the Exchange server in the Developing ColdFusion Applications. Also, you cannot establish a connection to an Exchange server if you require a special authentication step, such as requiring a VPN PIN or performing biometric authentication, on a server that is outside your firewall, and the authentication server then routes the messages to your Exchange server inside the firewall.

Use the cfexchangeconnection tag to close a persistent connection when you are finished accessing the Exchange server. If you do not close the connection, it remains open and does not time out.

The cfexchangecalendar, cfexchangecontact, cfexchangemail, and cfexchangetask tags also let you specify the open action connection attributes (but not the connection attribute) to create a temporary connection that lasts for the duration of the single tag’s activities, without requiring you to use the cfexchangeconnection tag to create the connection. In this case, ColdFusion automatically closes the connection when the tag completes processing.

The getSubfolders action can get information about the immediate subfolders of a specified folder (or of the top level of the mailbox), or information about all levels of subfolders. You must have a persistent connection to get the subfolders.

The query returned by the getSubfolders action has the following columns:

Column

Contents

FOLDERNAME

The name of the subfolder, for example, ColdFusion.

FOLDERPATH

The forward slash (/) delimited path to the folder from the mailbox root, including the folder name, for example, Inbox/Marketing/ColdFusion.

FOLDERSIZE

Size of the folder in bytes.

Note: The ColdFusion exchange tags, including cfexchangeconnection use WebDAV to connect to the exchange server. HTTP access must be enabled on the exchange server to use the tags.

Example

The following example opens a connection, gets all mail sent from spamsource.com, and deletes the messages from the Exchange server:

<cfexchangeConnection 
    action="open" 
    username="#user1#" 
    password="#password1#" 
    server="#exchangeServerIP#" 
    connection="testconn1"> 
 
<cfexchangemail action="get" name="spamMail" connection="testconn1"> 
    <cfexchangefilter name="fromID" value="spamsource.com">  
</cfexchangemail> 
 
<cfloop query="spamMail"> 
    <cfexchangeMail action="delete" connection="testconn1" uid="#spamMail.uid#"> 
</cfloop> 
 
<cfexchangeConnection 
    action="close" 
    connection="testconn1">
