•   WSS 3.0 / MOSS Server
•   SPTimer service
•   SMTP Relay
•   Active Directory management service
•   User account which has rights in AD (Delegate control for a specific OU)

About Incoming E-mail:

•   Feature of MOSS that enables SharePoint sites to receive and store e-mail messages and attachments in lists and libraries.
•   Users can upload documents to SharePoint document library.
•   Each list and library will have unique email address.

Simple Scenario:

Easy to configure, very less resources required.

You cannot use your existing corporate email client to send emails to Sharepoint lists.

Users have to remember all the email address for Sharepoint list items or it has to stored in local contacts list, there is no central location where you can store like Active Directory or GAL.

SMTP Configuration:

Server Configuration:

Though you have exchange server in organization we have to install SMTP service on one of the web front end server in Sharepoint farm. Make sure SMTP component is installed on one of your Sharepoint server, Sharepoint timer service will pick email/attachments from known local SMTP service only.
When you install SMTP service on your local Sharepoint server, it will create a domain under SMTP Virtual server.
Need not to configure anything manually, but few things needs to be checked before proceeding further.

Open IIS manager -> Default SMTP virtual Server -> Domains -> -> Properties
Check the drop directory location, default location would be "C:\inetpub\mailroot\Drop" where all the emails will be stored till Sharepoint timer service pick it up.  Sharepoint timer service will check this folder every 5 minutes (default).

Check the security level for the the folder "C:\inetpub\mailroot\Drop"
Make sure the 'WSS_ADMIN_WPG' local group has full control on this folder.



Client Configuration:

Client computers can be any windows operating system with email clients, either MS Outlook or Outlook Express to send email to SharePoint list.

Launch Outlook Express -> Create new email account
Display name: MOSS Administrator
email address:

Incoming Email Server type: POP3
Incoming Email server: MOSSserver
Outgoing Email server: MOSSserver
Username: mossadmin
Password: xxxxxx


Note: You might get POP3 server connection failure, we can ignore this because we have configured only SMTP server not the POP3 service on Sharepoint server.  For incoming E-mail configuration SMTP server configuration is enough.


Open outlook express and send an email to <DocLibrary> with attachment.
Check the folder "C:\inetpub\mailroot\Drop" and make sure the email dropped here in the format of *.eml file.





SHAREPOINT Configuration:

Global Settings from Admin:

Browse to Central Administration site -> Operations -> Incoming Email Settings (http://server:2345/_admin/IncomingEmail.aspx)

Enable incoming E-mail: Yes
Setting mode: Automatic
Directory management Service: No
Incoming E-mail server display address:
Safe E-mail servers: Accept mail from all e-mail server



Settings for Individual List items:

Browse to SharePoint site and create a document library.

Document library settings -> Incoming email settings

Allow this document library to receive e-mail?  - Yes 
E-mail address:  <DocLibrary>
E-Mail Attachments: Save all attachments in root folder
Overwrite files with the same name? -  Yes
Save original e-mail?  - Yes
Save meeting invitations?  - Yes
E-mail Security policy: Accept E-mail from any sender


Sending E-mail to a Sharepoint document library:

1. Sending email


2. Email dropped in SMTP drop folder


3. Email picked by Sharepoint timer service and uploaded to a specific document library.





Advanced Scenario:

Easy to configure, When we create Sharepoint list item it will create new contact entry in Active Directory as per configuration in Sharepoint Admin.  All the Sharepoint list address will be stored in Active directory as a contact object, where users can access from any client in a Domain.  We can use our existing corporate email client.

    Is there a method to accept digitally signed email?

  2. Ravishankar.n says:


    You left a important detail, wanted to point that out. Customer want to change the email address they send mail to, instead of send to something like test@Mossserver1.moss.corp.local

    The way to acheive this is to rename the name of the domain in the SMTP Virtual server in IIS manager.

    This will make sure that the users can send mail to some simple name like:

    The reason why they cant simply send to SMTP Virtual server is that anyother domain in the TO feild of the mail will make the VS to queue it in "Queue" folder instead of the Drop folder, failing the process.

    How do I receive incoming e-mail to sharepoint if all my mailbox accounts are hosted by a 3rd party company using POP 3? We don’t have an exchange server. Where do I put the usernames and passwords?

  4. Maung Maung says:

    Some default email meta data (name, email-from, email-to) are populated. Can it be customized to populated into other fields (instead of 'email-from', use 'from')?

  5. James Huang says:

    We actually found out it is easier to use SharePoint list to save and manage our emails. Unlike document library, there is an one-to-one relation between list item and email. The attachments from one email are saved as attachments of one list item. We are using email tracking list solution to track emails related to same issue. The product also let you to tag your email from email body.
