Remote Sessions per user (limited?)

Hi All

so i created a GUI to identify who has access to a mailbox, send as & full. all working fine.

The intention is to push this out to service desk and onsite staff. published the script in exe form from sapien tools, in the background in opens a remote PSSession under a set of creds that has access to our on prem exchange.

Is there a limit to how many remote sessions a single user can open on one host simultaneously ? if yes is this changeable ?

thanks

sample of connection below

$Username = "global\Username"
	$Password = ConvertTo-SecureString "Password" -AsPlainText -Force
	$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $password
	
	$SESJA_EX = New-PSSession -Credential $cred -ConnectionUri http://eurxhub02/powershell -ConfigurationName microsoft.exchange
	Import-PSSession $SESJA_EX
