Hi @Joel Rodriguez ,

Welcome to the Microsoft Q&A platform!

Based on your description, you are having issues using the Exchange Admin Center. HTTP 500 Internal errors can be frustrating. Here are a few steps you can try to resolve this issue:

Make sure IIS is configured correctly and all necessary components are installed and running.
Sometimes this issue can occur if the arbitration mailbox is unhealthy. You can check its status using the following PowerShell command:

Get-Mailbox -Arbitration

If any arbitration mailboxes are missing or unhealthy, you may need to recreate them.

Recreating the virtual directories for ECP and OWA can sometimes resolve this issue. You can do this using the following commands:

Remove-EcpVirtualDirectory -Identity "ServerName\ecp (Default Web Site)"
New-EcpVirtualDirectory -Server "ServerName" -InternalUrl "https://ServerName/ecp" -ExternalUrl "https://ServerName/ecp"
Remove-OwaVirtualDirectory -Identity "ServerName\owa (Default Web Site)"
New-OwaVirtualDirectory -Server "ServerName" -InternalUrl "https://ServerName/owa" -ExternalUrl "https://ServerName/owa"

Make sure your server has enough resources (CPU, memory, etc.) allocated to handle the load. Insufficient resources may cause services to fail.

Please feel free to contact me for any updates. And if this helps, don't forget to mark it as an answer.
