Sudden Outlook/Exchange Communication Problem
"Nikki Peterson" wrote in message news:... I would check the health of the network. Outlook will go into offline mode when it detects that there is no network connection. This is a feature that is intended to allow your clients to work seemlessly. Check the Event logs and see what is going on in the background just before you lost connection.

Hi Diane, Thanks for the reply. On my laptop I had the following updates installed on the 10th July, although Outlook was running without this issue yesterday, (14th July): Security Update for Windows XP (KB950760) Security Update for Windows XP (KB950762) Security Update for Windows XP (KB951376-v2) Security Update for Windows XP (KB951698) Security Update for Windows XP (KB951748) On the users laptop they had the following installed on the 9th July: Security Update for Windows XP (KB951748) Update for Windows XP (KB951978) Update for Outlook 2003 (KB953432): OUTLOOK Update for Outlook 2003: Junk E-mail Filter (KB953465): OUTLFLTR Although the user has just informed me that they have had the 'work offline' issue since they received their new laptop, back in June, so at least 6 weeks. They just never thought to mention it until yesterday.

Hi, We've been using Exchange 2003 & Outlook 2003 successfully for about 4 years now. We've never had any real issues, and it’s been working well. However, for some reason since Friday we've been getting communication problems between Exchange & Outlook. Yesterday I had a user complain that Outlook always opens in 'Work Offline' mode, no matter what mode you set it to be before closing. If you click the connection status menu bar in the bottom right corner of Outlook, you can untick 'Work Offline' and Outlook connects, and sends/receives mail without any problem. I thought it might be a corrupt profile, so I tried setting up a new profile for the user, but found that I receive an error message 'Name could not be resolved. Operation failed.' Usually we just enter exchange.domain.com & Joe Bloggs, and it resolves almost instantly, so I tried entering the server name & user name in every variation possible, just host name, full DNS name, i.e. exchange, exchnage.domain.com, user display name & full user name with prefix, i.e. Joe Bloggs, joe.bloggs, domain\joe.bloggs etc. Still nothing! In the end I left the user with the old profile, and told them I'd look into it. However, now this morning I have come in, and found that my Outlook is opening in offline mode by default as well, although as before, I can untick 'work offline' and Outlook connects & sends/receives fine. Also my 2nd mailbox (helpdesk) wasn't opening; I think the error message was 'mailbox unavailable' or something. So I edited my Outlook account, removed the mailbox from the 'advanced' 'open additional mailbox' tab, then tried to add it again. However, I now receive the same 'Name could not be resolved. Operation failed' error message as our other user. I've tried rebooting the exchange server, changing the default language to UK English (which I read in MS KB 838800 could fix the issue), but still the problem persists. Could anyone shed any light on the issue, or provide a possible fix? We're running Windows 2003 Server Standard Edition SP2, Exchange 2003 SP2 Standard Edition, clients are Windows XP SP3, Office/Outlook 2003 SP3 (v11.8169.8172). Many thanks Ben- Hide quoted text - - Show quoted text -
