Migrating from exchange 2016 to 2019.
Exchange host 2019: elemsex01
I get "HTTP Error 503. The service is unavailable" when browsing to:
Hostname correct certificate: https://elemsex01.corp.elevation.se/ecp/
Local host: https://localhost/ecp/
DNS record: https://remote.corp.elevation.se/ecp/
I have read all threads and blogs I can finned but nothing is helping me.
Do someone have any idea how I can continue my trouble shooting?
