IP Address Ranges

To ensure full connectivity, consider allowing the following IP address ranges as specified by Microsoft:

• Azure Datacenter IP Ranges: You can download the latest Azure IP ranges from Microsoft's official IP ranges documentation.

Additional Steps

1. DNS Resolution:
   • Ensure that DNS resolution is working correctly for the above URLs.
2. Update Firewall Rules:
   • Update your firewall rules to allow traffic to these URLs and IP addresses.
   • Ensure both HTTP (port 80) and HTTPS (port 443) traffic are allowed to these endpoints.
3. Check Connectivity:
   • After updating the firewall rules, use a web browser or network tool to verify connectivity to these URLs from the server where you are installing Office 365.

Testing Connectivity

You can use PowerShell to test connectivity to these URLs. For example:

powershell
Test-NetConnection -ComputerName officecdn.microsoft.com -Port 443

Summary

By ensuring that all the necessary URLs and IP addresses are accessible, you should be able to successfully install Office 365 on your Windows Server. If you continue to experience issues, please let me know, and we can explore further troubleshooting options.
