I am doing a powershell script that can update the Account Expires field in the AD based on sAMAccoutname but i faced some issue on Set-ADUser powershell command when it tried to update the Account Expires field in AD. I tested several way with various combination of command option but none of them work as expected

You need to input a valid datetime.
For instance if you want to let the account expire in 1 month.
$date = Get-Date
$dateExpiry = $date.AddMonths(1)
Set-ADUser xxxx0242 -AccountExpirationDate $dateExpiry
Please note that the returned int64 value can easily be converted to a usable datetime for instance to add 6 months to it:
$currentExpiry = (Get-ADUser xxxx0242 -Properties AccountExpires).accountExpires
[datetime]$expireDate = $currentExpiry
$newExpireDate = $expireDate.AddMonths(6)
Set-ADUser xxxx0242 -AccountExpirationDate $newExpireDate
Hope this helps!
