How to fix "Unable to install Microsoft 365 PowerShell modules" error?

When you try to install the MSOnline module using the Install-Module -Name MSOnline command, if there is an error similar to "Unable to download the list of available providers. Check your internet connection.", it might be due to any of the following reasons:

1. No internet access: Check if there is proper internet connectivity in the Applications Manager installed server.
2. TLS 1.2 not present:
   
1. To check the available TLS versions, execute the below command in the admin PowerShell window: 
   
   

   [Net.ServicePointManager]::SecurityProtocol
2. If the output does not have the value Tls12, then TLS version 1.2 is not present 
   
3. To enable this, open the admin command prompt and execute the following commands: 
   
   

   REG ADD HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 
   REG ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1
4. Once done, open a new Powershell window and check if the Tls12 is enabled.
   
5. If enabled, then try installing the MSOnline module.
   

If the issue still persists, contact Microsoft Support to troubleshoot the issue as the Install-Module commands are the direct commands provided by Microsoft.
