disable duplicate detection RRS feed

  • Question

  • Hi everybody,

    I know duplicate message detection is a nice feature at all.

    I have one requirement (some kind of archiving) in which this is really not wanted.

    I've seen that it might be possible to disable this at all by setting the following key to 0:

     Name>\<Private/Public-Guid>\Track Duplicates (in hours)

    As I don't want to disable duplicate detection at all but only for only recipient mailbox I didn't go into that direction.

    Does anybody knows if it is possible to disable this on per user / per mailbox basis?

    Thanks a lot,

  • I don't believe that there are any settings for individual mailboxes.

    Is this related to journaling and you have the journaling mailbox on the same database as your users?  To be an actual duplicate message, there are a number of requirements and as such, can cause a large perf hit if set for a very long time.  This is still true if you have this set for 1 mailbox, database, server.
