[ActiveDir] OT: Exchange Email Deletion Policy

[Burkes, Jeremy [Contractor]]

Everyone,             We are setting up an email deletion policy at my organization.  I have tested and understand how the recipient policy works and the entire email deletion process works.  One thing that is a little confusing is the fact that the email deletion policy works off a hidden field for each item in a user’s mailbox that I will call modified date field.  Meaning if I copy a message into my mailbox that has a received time of over 30 days and the email deletion policy deletes anything it over 30 days the message does not get deleted.  I know this is because of the modified date field.  What I want to know is when does Exchange decide to change this date from the time it was created to a later date.  Is this based on a user moving a message to a new folder, replying, and forwarding?  I want to educate our help desk, users, etc. on what will be deleted and when and I cannot find any documentation on the internet that explains when and how the modified date is changed/updated.  TIA.   Jeremy ------------------------------------------------------------------- Jeremy Burkes Strategic Systems Programs Management Information Systems Help Desk: 202-764-1442        Work: 202-764-1270 |         Fax: 202-764-1503 [EMAIL PROTECTED]
