According to machine translation, your question is:
After installing Exchange server, I cannot access ECP and get an error 500.
Below are several questions in order to narrow down this issue:
- What is the detailed Exchange version (including the CU version) are you using?
- What is the detailed error message? If possible please post a screenshot. (Don't forget to hide your personal information)
- Would you also have problems with opening Exchange Management Shell?
If Exchange Management Shell works fine, to me the possible cause is the Exchange OAuth certificate hasn't been published yet and you may need to wait some time (up to 48 hours) for it to work.
