RE: How is bandwidth managed in cached mode?
Hi,
I have been responded in Exchange2000.admin newsgroup. Please check my
reply and follow up in that newsgroup. For you convienience, my post is
included.
---------------------------------
Mark is right. Actually it is Outlook client that causes this problem but
not Exchange. For the Exchange performance issue, I recommend reading this
white book,
Exchange Server 2003 Performance and Scalability Guide
http://www.microsoft.com/technet/prodtechnol/exchange/2003/library/perfscalg
uide.mspx
And my suggestions are as below:
1. Limit the message size in Exchange if your server hardware and network
bandwidth is not powerful enough.

http://support.microsoft.com/?id=322679
2. Configure Outlook client to download header for larger message. This
option only applies to offline mode, so the workaround is as below:
Set Exchange Server account to work offline
===============================
1. Start Outlook if it is not currently running.
2. On the Tools menu, click "E-mail Accounts".
3. Click "View or change existing e-mail accounts", and then click Next
4. Double-click the Microsoft Exchange Server account to access its
properties.
5. Click the More Settings button.
6. On the General tab, click to select the "Manually Control Connection
State" check box.
7. Under "Default connection state", click to select the "Work offline and
use dial-up Networking" check box. You can also click to select the "Choose
the connection type when starting" check box so that you work either
offline or online.
8. Click OK.
9. Click Next, and then click Finish.
Configure Exchange Server account to download only headers for items larger
than XXX KB
===============================
1. Start Outlook.
2. On the Tools menu, click Send/Receive -> Send/Receive Settings -> Define
Send/Receive Groups.
3. Make sue to click the All Accounts group name (or the name of another
Send/Receive group that you will use while you are working offline), check
the "Schedule an automatic send/receive every x minutes" box under "When
Outlook is Offline"
4. Double-click the All Accounts group name (or the name of another
Send/Receive group that you will use while you are working offline).
5. In the Accounts bar, click Microsoft Exchange Server, and then click
Inbox folder.
6. Select the "Download complete item including attachments" option and
then check the "Download only headers for items larger than XXX KB" box.
7. After you set the other options as desired, click OK, and then click
Close.
8. Restart Outlook, and then select to work offline.
