exchange server 5.5 registry

[marreve]

Does anyone know the registry tweak to change the time intervals outlook receives and sends email. I believe the default is every minute. Thanks

Exchange is supposed to send a UDP packet to outlook when new mail arrives for notification. Are these clients using POP3 to access the server or somthing?

 

[marreve]

No, users are only using our inside e-mail. We are having about 80% outlook e-mail broadcast traffic on our network from users checking their mail and it is slowing us up.

Thanks for your reply

I assume you are using IP and not IPX.

 

[marreve]

correct.

 

[isguyatlanta]

It should not behave like that, how many users 10,000?

 

[marreve]

no, about 1200, with about half comeing across a WAN, and a couple ISDN lines. Any ideas?

Hmm... Was this a recent increase in braocasts or has it grown with the number of users? If it is recent check the harware layer, you may have a bad card or port on the switch or cable. If you have a good switch, see what it thinks about the link.

Also... From MS Q232182 this is at the bottom about reducing server generated traffic, the search term that returned this was 'excessive', I don't know if you are multi site or not:

Upgrade or increase the available network bandwidth. This is the best solution because it provides enough bandwidth for all applications. How much additional bandwidth is needed depends on network use.

Make physical sites with low bandwidth separate Exchange Server sites. They can then be connected by X.400 connectors. X.400 connectors have several tuning and performance optimization settings that can be configured for connectivity across slow WAN links.

Set message size restrictions on the MTA to reduce network traffic. This can be done in the Microsoft Exchange Server Administrator program, on the General tab of the MTA Properties page. This way users are restricted from sending large messages that can cause severe problems on the network.

Schedule public folder replication for after hours, or for times when there is extremely low traffic or no traffic on the network.
