I'm having a real difficult time connecting to my email server. We have our email hosted offsite and use Exchange 5.5 with Outlook 2003 clients.
If someone has a large attachment or email to download Outlook gets slowed to a crawl when retrieving that email. I. E. I've got a 2MB email to download, OUtlook begins to download the email and after a small amount of bytes are downloaded the email slows to an incredibly slow crawl and ends up timing out. This is happening to all 23 users in my office. Smaller emails always download fine.
Because of this problem I decided to play with the connections settings and switched it over to a secure connection. Once I did this all emails no matter the size downloaded fine. A couple of days ago we began getting errors intermittently indicating:
Task 'mail.xxx.com - Receiving' reported error (ox800CCC0F): 'The connection to the server was interrupted. If this problem continues, contact your server admin or ISP.
If I keep hitting Send/Receive I error out with the above error about 60% of the time, which is causing problems with my users since they automatically try to connect every 5 minutes. Sometimes they don't get emails until over an hour after they should have come in.
I have talked to my email host and they indicate there are no problems on their end. I have talked to my firewall support and they don't see an indication of any problems on their end.
Any help here would be great!! I am at a loss. TX!
