Mail delivered to one user is slower RRS feed

  • Question


  • We have one Exchange 2007 SCC Active/Passive cluster running Windows 2008. I have a user who is using Outlook 2007 and claims he receives email later than this colleagues.

    For instance, if one email was address to user1@domain.com (this guy), user2@domain.com and user3@domain.com, he says that User1 and User2 recv the email before he does, even when all of them are on Online with Exchange mode.

    I had some questions about this -

    i. Is there any way to show when a mail was actually delivered to the mail client (as opposed to the mailbox)

    ii. If he was using Cached mode, is there any way to increase the frequency of how often Outlook checks for new messages?

    iii. Whether in Cached/online are there any settings within the mailbox that would affect how soon emails are delivered?

  • 1.  You could enable Outlook Logging.  But those files can be hard to read.

    2.  Not that I know of.

    3.  Exchange 2007 notifies Outlook via a UDP message when there's a new message.  Is it possible that the user in question could have a personal firewall that's blocking the message, or maybe he's behind a firewall that's dropping the message?

  • Hi,

    Please verify if the performance issue would occur if they use OWA.

    Please try to disable Anti-virus application and then check the issue again.

    As Ed said, please check settings for Firewall.

    please try to compare the outlook performance when there's no other application running on the machine.

    Regards,

    Xiu
