It sounds like a Network issue I would try just to disable the nics and the enable and see if you have connection restore, could be bad NIC card or switch port hug up. -----Original Message----- From: David Iles [mailto:davei@xxxxxxxxxxxxxxxxxxx] Sent: Wednesday, March 01, 2006 6:09 PM To: [ExchangeList] Subject: [exchangelist] Outlook is requesting Data http://www.MSExchange.org/ We have 3 backend exchange servers (no frontend). Due to other issues all but 5 users are on 1 server (approx 450 but only approx 150 active) 2nd server has the other 5 users. The 3rd acts as an archieve for all emails. Approx once every 2 weeks users see "Outlook is requesting Data". Processors are normal, nothing being reported in the logs but a reboot of the main server sorts the problem. Upto this last 2 weeks, if this occured it was mostly on a Monday but this last 2 weeks it has happened on a Tuesday and today (Thursday). Any thoughts.
