Action Required: Upgrade ExchangeOnlineManagement PowerShell Module to Version 3.10.1 or Newer
This issue has been around since 3.9.0 onward modules (and again prior to that in 2.x.x versions too). Microsoft should align (the MSAL version) them with other modules as its common to have multiple ones loaded at a time.
The latest version of Microsoft.Identity.Client on NuGet is 4.90.1 , however ExchangeOnlineManagement 3.10.1 loads Microsoft.Identity.Client 4.83.1 as it comes packaged with older versions, resulting in conflict with Connect-MgGraph, Connect-Entra etc. which loads\packs with 4.90.0
