Hi @Quyen Ngo Ngoc ,
Welcome to post our Q&A forum!
Regarding your error messages, based on my experiences. Here are some steps to consider:
- Wait and Retry: As the message suggests, wait a few minutes and try again. Sometimes transient issues resolve on their own.
- Check Credentials: Ensure you’re using the correct username and password for the ECP login.
- Review Logs: Check server logs for any specific error messages related to ECP access.
- Network Health: Verify network connectivity between your client and the Exchange server.
- Server Health: Confirm that the Exchange server is operational and not overloaded.
If these steps don’t resolve the issue, further investigation might be necessary. Good luck, and I hope your ECP access gets back on track!
