It appears that a maximum connection limit is set up for the Exchange server, yet the connection limits set up for the protocols far exceed the number of active workstations. Our network is small, with about 20 to 30 workstations. Can you please advise me on protocol connection limits and how they work? Or could it be another problem that is causing this to happen?
You can also configure connection limits on the default SMTP server within Exchange System Manager (ESM). The default settings should be adequate for your organization, but it's possible that they have been changed.
To configure SMTP connection limits in ESM:
- Open ESM and drill-down through Administrative Groups -> First Administrative Group -> Servers -> YourServer -> Protocols.
- Right-click on Default SMTP Virtual Server and select Properties.
- In the General tab, check the number of permitted connections. The default value should be 500.
- Finally, go to the Delivery tab and click Outbound Connections. The default values should be 10.
