We have an issue with our exchange 2003 server. about 4 or 5 people have been complaining that they don't receive any emails for a few hours then suddenly they will receive a whole bunch at once.This happened this morning with a senior manager (opps) he said he hadnt received any emails from about midday yesterday. I went down today and when i did a manual send / receive he received about 20 emails and heaps with time stamps of yesterdays date. He assured me that he was always connected to exchange as he had been sending emails yesterday but not receiving. It has also been happening to a fellow I.T college so i'm pretty sure its not a user issue.I have checked exchange tracking centre and it reports that the messages were delivered to the mailstore at the correct times. Im thinking this could be some type of outlook issue and probably not exchange... All the people in question has outlook set to do an automatic send / receive ever 10 mins. Perhaps this could be an outlook problem? all clients are using outlook 2003. As mentioned this issue has only been reported by about 5 peoples. We have about 250 mailboxes... anyone got any ideas?

I have been having this same issue with my Exchange server. My user's are reporting a 3-4hr. delay in receiving outside email. Whats weird is when I look up the emails to see if they were blocked in our spam firewall it says delivered? But nothing is delivered? Any Ideas??? -Jon

You don't see any queues stacking up then? Do you have a BES server in your org or any other 3rd party mail application common to these few users? i've also found that the symantec desktop a/v can severely slow mail delivery if it is set to scan MAPI.

To help isolate the problem, if you have OWA setup, you could check OWA to see if the mail is actually in the mailbox or not. I would think it would be in the mailbox and there is some connection issue between outlook and the exchange. You mentioned they have send/receive every 10 minutes.. are they setup using POP3/smtp or IMAP ? I've seen where some outlook users connected via IMAP are temporarily disconnected either through a faulty VPN or some other network outage. Some users would have their outlook setup as "offline" then and would have to manually set it back online to get mail.

There are no queue at all. But i did check OWA and the emails were showing up in there. On one of the the affected machines I deleted the whole outlook profile and recreated it. He hasent had the problem since then so maybe that has fixed the problem. All users use SMTP

Hi, its most likely the Exchange Cache option in the outlook profile for these users. for one user that faces the problem, try to remove the Use Exchange Cache mode option from within the outlook profile of that user, and am sure you will be able to see all the emails. try to update your outlook 2003 with the latest service packs from office update site. your problem is from the Cache Mode that outlook is using. Please let me the status of this problem. Regards, Alaa
