You can use the imEMM.config file to customize the user experience of Email Management provided by iManage Work Desktop for Windows. You can use the following options:

If your iManage Work administrator changes the settings in the application configuration files and the files are downloaded to your machine, Microsoft Outlook detects and applies the changes in the background. You can then see the latest configurations without restarting the application.


This feature does not apply to ribbon bar customizations or other settings which are only read once by Microsoft Office during application launch.

Client-side filing options

In iManage Work 10.2 and later, the iwWCS.exe process is available individually on each user's machine to handle different filing related tasks (similar to the iManage Work Communications Server that communicates with the iManage Work Server to handle server-side filing). The iwWCS.exe starts running as soon as the users' machines are started.


  • iManage Agent Service must be installed on the users' machines to ensure that the iwWCS.exe process starts automatically.

  • The UseClientSideFiling option does NOT use the iwWCS.exe process.

The following options are available in the wcs_config group to enable you to configure the client-side filing behavior.





By default, the Microsoft Outlook client uses client-side filing even if the server supports server-side filing when:

  • Using the File option or

  • Users drag-and-drop emails into the iManage Work panel.

If this option is disabled, server-side filing is used if available.

NOTE: UseClientSideFiling does not control the filing behavior of the Send and File action, or the Inbox Filer and Sent Items Filer.

1 (True) Default

0 (False)


Enable this option if you want to use client-side filing for the Send and File action.

1 (Enabled)

0 (Disabled) Default


When using client-side Send and File (from the Sent Items folder), this option controls whether the BCC information should be retained or not.

The default setting is off, which means that messages filed using client-side Send and File will contain BCC information that may be visible to other recipients/users in the firm. If you do not want BCC information saved in iManage Work along with the message, enable this option by setting it to 1.

NOTE: This setting is used with the client-side Send and File only.



1 (True)

0 (False) Default


Enable Inbox Filer so that it can monitor and file all the emails in your Inbox that are sent with a luggage tag in the subject and no iManage Work folder email address in the recipient field, and then files the emails and marks them as filed.

NOTE: Inbox Filer and Send and File are configured separately. If you enable Send and File and disable Inbox Filer, only the Send and File feature works. If you enable Inbox Filer then both Send and File and Inbox filer work. You cannot disable Send and File by enabling Inbox Filer.



TRUE (enabled)

FALSE (disabled) Default


Time duration in seconds after which the Inbox Filer process is invoked. The default interval is 120 which means that the Inbox Filer runs after every 2 minutes to check for and file emails.



Default value (in seconds): 120


The number of days Inbox Filer needs to regress to look for emails. The default value is 30 days (1 month).



Default value: 30


Inbox Filer processes emails only if the maximum number of recipients in the email is less than SyncRecipientsLimit. Change the default value as desired to ensure that general emails sent to a large number of people or the entire organization do not get filed.



Default value: 50


Enable this option to ensure that client-side filing is used for mapped folder.



TRUE (enabled)

FALSE (disabled) Default


Use this option to ignore certain type of email messages while processing mapped folders. Separate the message classes by semicolon.



Default value: IPM.Note.WorkSite.Ems.Error

(Message class for emails that could not be filed to iManage Work and resulted in an error.)


By default, the emails in mapped folders are processed in a batch of 10. Once the first 10 emails are processed, the next 10 are processed, and so on.

NOTE: After the emails are processed, it may take the Inbox Filer a time ranging from 1 to 10 minutes to mark them as filed.



Default value: 10


The number of filing and marking attempts to make before ignoring an email in a mapped folder.



Default value: 15


Time duration in minutes after which the mapped folders process is invoked. The default interval is 360 which means that the process runs after every 6 hours to check for and file emails.

Default value (in minutes): 360


Enable this option to ensure that processing of mapped folders begins as soon as the iwWCS process starts; without waiting for the MappedFolderInterval to elapse.



TRUE (enabled)

FALSE (disabled) Default


The time duration in minutes for which Inbox filer waits before processing new emails.



Default value: 15

Offline filing options





The records of filed emails that are maintained in the offline filing tables are deleted automatically after 7 days. Modify this value to keep the records for a longer or shorter duration.

Default value: 7


Since there may be a limit for the amount of data that can be sent using RestAPI, the emails are batched before they are sent to Work Communication Server. By default, 10 emails are sent together for one iManage Work location. If there are multiple locations from different libraries, the emails are processed in a batch based on the libraries.

Default value: 10


If there are errors during filing the process, filing is attempted up to FilingRetryCount times. The FilingRetryCount is incremented by 1 for each filing attempt. After reaching the default value, no further attempt is made to file to the emails and they are marked as Error at the last attempt.

Default value: 5

Additional options





Specify whether Outlook should automatically connect to the iManage Work Server when it starts.


"LoginOnStartup": 0

1 (True) Default

where 25 = Custom1, 26 = Custom2, 27 = Custom3. Also, "." is a mandatory delimiter between items. The only supported values are Custom1 through Custom12, Custom29, and Custom30. For more information on numeric values for supported custom fields, see Appendix A - Custom Attribute IDs .


  • The workspace where you are filing the email should include the default "E-mails" folder, and should have the same custom values already set. You can specify the default email folder using the iManage Work Server registry setting, Default Email Folder. For more information, see Appendix C - Server Configuration Options of iManage Work Server Administration Guide.

  • The EnableClientMatterTagFormat option value should be set to 1 (Client.Matter) or 2 (Client.Matter + FID).
