I don't have all to much experience with Sharepoint, so this is a bit of a learning experience for me. Your insight is greatly appreciated!
Here is our current setup: We are an engineering firm and create a new Job # for each job we have which then gets entered into our internal database along with the basic details on that job like its status, the client, the engineer, the drafter, etc. This custom site connects to our Exchange 2003 server to grab all the info on the client and any other companies involved. This is so that when a user clicks on a contact it comes up with all their info such as Name, phone, and address. After that is done, a new folder is setup in the public folders in Exchange for that job. Now whenever there is correspondence relating to that job our guys can email that job number, ex A10000@ourdomain.com and that email will go into the A10000 folder. This is basically for archiving purposes and makes it easy for people to access old emails relating to a certain job. There is a structure to this though, so we have a folder for the office location (2 offices) and then subfolders for the different years and then the job number. Ex City -> 2012 -> A10000.
Now what I want to do is move to Exchange Online and use Sharepoint on a local server. My question is: In sharepoint, can I have a similar setup where an general admin person can easily create a new folder for a job and have the email go into that folder? I am pretty sure I can get all the stuff our internal database does working on sharepoint through a web part, so its really just the email issue.
If you want any further details, please let me know!
