Set Azure AD password to never expire
I use Office 365 for my family’s e-mail and document storage, but they are not keen on regularly changing passwords - the IT department receives a lot of hassle 
Although the UI does not allow for the passwords to be set to never expire, PowerShell does.
First off, we can get the status of all users:
## See the status of all users
Connect-MsolService;
Get-MsolUser | Select UserPrincipalName, PasswordNeverExpires;
Or we can get the status of a specific user:
## See the status of a specific user
Connect-MsolService;
Get-MsolUser -UserPrincipalName <user id>| Select UserPrincipalName, PasswordNeverExpires;
The «user id» value is the identity that the user uses to log in, e.g. username@domain.com or username@tenant.onmicrosoft.com.
We can get all users who have a password set to expire:
## Get all users with passwords set to expire
Connect-MsolService;
Get-MsolUser | where {$\_.PasswordNeverExpires -eq $false} | Select UserPrincipalName;
We can change all users with passwords set to expire:
## Change all users to have passwords that never expire
Connect-MsolService;
Get-MsolUser | where {$\_.PasswordNeverExpires -eq $false} | Set-MsolUser -PasswordNeverExpires $true;
Or change only one user:
## Change one user to have a password that never expire
Connect-MsolService;
Get-MsolUser -UserPrincipalName <user id> | Set-MsolUser -PasswordNeverExpires $true;
So in short, where the UI in Azure AD does not offer us the capability to manage users in relation to the expiry of their passwords, PowerShell does.
