+.SYNOPSIS
+This script defines a function `Connect-EXOAdvanced` that establishes a connection to Exchange Online.
+It ensures that the required ExchangeOnlineManagement module (version 3.0.0 or higher by default) is installed and loaded.
+The function supports single and multiple session connections, with optional parameters to control the connection details display and session prefix.
+If the required module is not found, the script attempts to install it.
+The function returns the connection information or null if the connection fails.
+
+.PARAMETER DoNotShowConnectionDetails
+ Optional switch to hide connection details.
+.PARAMETER AllowMultipleSessions
+ Optional switch to allow multiple sessions.
+.PARAMETER Prefix
+ Optional string to specify a prefix for the session.
+.PARAMETER MinModuleVersion
+ Optional parameter to specify the minimum version of the ExchangeOnlineManagement module (default and minimum supported version is 3.0.0).
+
+.OUTPUTS
+Microsoft.Exchange.Management.ExoPowershellSnapin.ConnectionInformation. The connection information object for the Exchange Online session.
+
+.EXAMPLE
+$exoConnection = Connect-EXOAdvanced
+This example establishes a connection to Exchange Online using the default settings.
+
+.EXAMPLE
+$exoConnection = Connect-EXOAdvanced -AllowMultipleSessions
+This example establishes a connection to Exchange Online and allows multiple sessions.
+
+.EXAMPLE
+$exoConnection = Connect-EXOAdvanced -AllowMultipleSessions -Prefix Con2
+This example establishes a connection to Exchange Online, allows multiple sessions, and specifies a prefix "Con2" for the session.
+
+.EXAMPLE
+$exoConnection2 = Connect-EXOAdvanced -MinModuleVersion 3.5.0
+This example establishes a connection to Exchange Online and specifies a minimum module version of 3.5.0.
