I have a request to setup a doc lib to capture all emails for a particular project and file it in a particular folder within the library. Here's the a quick run thru:
- I have a doc lib called BCDL with the incoming email option enabled. The email address for the doc lib is bcdl@mydomain.com.
- The user will, in advance, manually create folders with naming convention of "Proj-XXXXX" where XXXXX is the project number
- All emails (with or without attachment) going to bcdl@mydomain.com will be forwardedto the BCDL library. The subject of the email will include the "Proj-XXXXX" text in it. Note, the position of this text can vary is it is a response to an email.
- After the email arrived, a workflow or task of some sort needs to parse the subject and look for the "Proj-XXXXX" and move that email to the "Prox-XXXXX" folder which was pre created in step 2.
In summary, I want to setup a Doc Lib where all incoming email will be filed to the respective "Proj-XXXXX" folder parsed in the subject line.
Not sure where to start. I have look at the doc lib, one of the issues I am seeing is that email to a doc lib MUST contain an attachment or it will not accept it. A custom list does not have incoming email option.
Update 20/11 after answer and comments:
The problem with grouping is that I can't apply permission to it. Someone would have to apply the permission to each entry. With folder, the user would apply the permission when the folder was first created.

Why Microsoft don't extend the option to folders is beyond me.
