I have an issue with our Exchange Admin Centre.
When attempting configuration changes to mailboxes in EAC, running into several issues:
- The Organizational Units (OUs) are not showing up
- When clicking 'browse' to see a list of users, nothing shows up
- When attempting to run reports, getting errors
Tried with IE and Chrome.
We are running Exchange 2013 and the server has already been restarted but did not resolve the issue.

somehow exchange did not able to query AD DNS from browser quickly

check if EMS response time is fast

If yes, try adding host file entry for AD domain name and reboot the exchange server and check
