Hi bpatrickr,
According to your description, I'd like to confirm if you have tried to set up user passwords to never expire using the following steps.
1. Install Window PwerShell: http://technet.microsoft.com/en-us/library/jj151815.aspx
2. Connect to Windows PowerShell using your company admin credentials. Run the following cmdlet:
Connect-MsolService
3. Do one of the following:
• To set the password of one user to never expire, run the following cmdlet by using the UPN or the user ID of the user:
Set-MsolUser -UserPrincipalName <user ID> -PasswordNeverExpires $true
• To set the passwords to never expire for all the users in an organization, run the following cmdlet:
Get-MSOLUser | Set-MsolUser -PasswordNeverExpires $true
For more information: Set up user passwords to never expire.
Generally, admin can use the steps above to set user passwords to never expire successfully. If you cannot use the steps above, I'd like to confirm if there are any error messages when you are trying the steps? If yes, could you provide the details about the error message for further troubleshooting?
In addition, if there is anything unclear about the steps, feel free to let me know and I will assist you to complete the process.
Thanks,
Tracey Wang
