Hello, @郭志成,

Welcome to the Microsoft Q&A platform!

The error log indicates that the Microsoft.Exchange.RpcClientAccess.Service.exe is crashing due to an issue with ntdll.dll, which is causing the service to restart and the Outlook client to repeatedly connect to the Exchange server.

Here are a few steps you can try to resolve this problem:

1.Update Exchange Server: Ensure that your Exchange Server is up to date with the latest patches and updates. Sometimes, these issues are resolved in newer updates.

2.Check for Corrupted Files: Run the System File Checker (SFC) tool to check for and repair corrupted system files. Open Command Prompt as an administrator and run the command:

sfc /scannow

3.Reinstall Exchange Server Components: If the issue persists, consider reinstalling the Exchange Server components related to the RPC Client Access service.

4.Check Event Viewer: Look for any additional errors or warnings in the Event Viewer that might provide more context or clues about the root cause of the issue.

5.Review Antivirus/Firewall Settings: Antivirus or firewall settings sometimes can interfere with Exchange services. Ensure that your antivirus and firewall are not blocking or interfering with the Microsoft.Exchange.RpcClientAccess.Service.exe.

If the above routine troubleshooting has not solved your problem, you may get some inspiration from this 3rd-party document: RPC Client Access Service keeps restarting in Exchange 2013 « MSExchangeGuru.com.
