This V3 EXO PowerShell module contains new REST API backed Exchange Online cmdlets which doesn't require WinRM for Client-Server communication. You can now run these cmdl
ets after turning off WinRM Basic Auth in your client machine thus making it more secure.
Unlike the EXO* prefixed cmdlets, the cmdlets in this module support full functional parity with the RPS (V1) cmdlets.
V3 cmdlets in the downloaded module are resilient to transient failures, handling retries and throttling errors inherently.
REST backed EOP and SCC cmdlets are also available in the V3 module. Similar to EXO, the cmdlets can be run without WinRM basic auth enabled.

The latest EXO V3.7 module is released which includes significant memory improvements. You’re currently using an older version and we recommend upgrading to V3.7 for enha
nced performance.
