We have a problem where emails take a long time (reletive to file size) to get from our exchange server (2003) to our outlook 2003 client.
The sent and received dates are fine, it's the time difference between the received and created dates (time the email is added to the local PST) which are a worry. For each Mb in size add 2 minutes between these 2 times. An email with a 10Mb attached takes about 20 minutes to get from exchange to outlook/OWA.
The same email going out gets to an external recipient in an acceptable time.
There is no delay on internal emails only those coming in.
There is no virus scanning in place on the server and we've tried clients with and without virus scanning (McAfee Virusscan Enterprise). Incoming and out going email is scanned by Websense (mailcontrol).
We see this behaviour for emails dating back over 5 years we've just not picked up on it before as the 'cretaed' date field in outlook is not always used.
Any help greatfully received.
