How message forwarding works (exchange 2010 )?

    Question

  • Hi Team,

    I have this simple query trying to figure out exact answer of it.

    When a person send an email of 1 MB to 10 people the mail is delivered to respective database where recipients mailbox is stored.

    Now if out of those 10 people forwards same message to 10 more people.

    So what I would like to understand is complete storage process.

    How much space it will take for example stated above is it going to take 20 MB ? I know it will not but would like to know from you experts.

    What happens when any one forwards email to some one else.. how message id changes.. how pointers are created.. how much space will be utilized.

    Please help.

    Thanks

    Abhishek

    If a 1MB message is sent to or forwarded to 20 people, it will take 20MB of space in the database.

    Use the mailbox calculator to determine how to size storage.

  • Hi,

    If you want to remove audit log for individual mailbox, please run below command to remove:
    Set-Mailbox -Identity "Naresh Singhal" -AuditLogAgeLimit 00.00:00:00

    Moreover, you can modify it in global level, for your reference:
    Set-AdminAuditLogConfig -AdminAuditLogAgeLimit 00.00:00:00

    This will warn you of the implications before the log deletion continues; it states it will effectively delete all logs after approximately 60 minutes. After you have cleared the logs, you can revert back to the default setting using the following cmdlet:
    Set-AdminAuditLogConfig -AdminAuditLogAgeLimit 90.00:00:00
