Exchange 2007 high bandwidth usage RRS feed

  • Question

  • Exchange 2007 8.3 (83.6)

    We have seen some heavy usage between our server at the data center and remote clients over a 3mb dedicated line.  

    Some are macs running OL2011, and other are Win7 with Office 2010 running in cached mode.

    All we can tell is some of the devices will swap 200 mb of data and tie up the line. I cant find any errors on exchange and it appears to be working fine for people over the remote 50mb links.  

    When looking at the client sucking up bandwidth there is no indication why on the client. It simply looks idle.

    Are there any known issues with OL2010/2011/EX2007 that generate high bandwidth utilization.

    Thanks, Grady Vogt

  • Our issues ended up bing Mac users that had 42K emails in the inbox.

    We clean them up and moved stuff to other folders and it appears to be OK.

    Thanks, Grady Vogt
