Powershell update value with concatenated objects

I am trying to update the UPN for a list of users in O365.  I have connected via Powershell and am able to update individual entries however my Powershell is not strong enough to do them all in one shot.

Get-MsolUser | where-object {$_.UserPrincipalName -eq ($_.firstname) +
"." + ($_.lastname) + "@domain.com"} | Set-MsolUserPrincipalName -NewUserPrincipalName ($_.firstname.substring(0,1)) + ($
_.lastname) + "@domain.com"

you cannot call a method on a null-valued expression.
At line:1 char:1
+ Get-MsolUser | where-object {$_.UserPri ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull

basically trying to set the UPN to first initial + lastname instead of the firstname.lastname.  I have fixed dirsync to create the UPN this way however need to fix all the users which are set the wrong way.  Any help with the code would be appreciated.

Something like this should work but not tested.

Get-MsolUser | where-object {$_.UserPrincipalName -eq ($_.firstname) | %  {
$nuname = ($_.firstname.substring(0,1)) + ($_.lastname) + "@domain.com"
Set-MsolUserPrincipalName -NewUserPrincipalName $nuname 
}

The problem is that the set-msoluserprincipalname also requires the old userprincipalname.  Both would need to be stored in the variable and be called individually.  Tried to accomplish this but it did not work for me.  It would have piped it for my command but with your version it would need to be saved to the variable.

You already have the UserPrincipalName going through the pipeline, $_.UserPrincipalName. The brackets are messed up though.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I prefer subexpressions to concatentation so I've done that below.  The only issue with becraig's was that it needed to specify the -UserPrincipalName parameter for Set-MsolUserPrincipalName.  You could use the intermediate variable, but I've just specified the value directly.
Get-MsolUser | where-object {$_.UserPrincipalName -eq "$($_.firstname).$($_.lastname)@domain.com"} | % {
    Set-MsolUserPrincipalName -UserPrincipalName $_.UserPrincipalName -NewUserPrincipalName "$($_.firstname.substring(0,1))$($_.lastname)@domain.com"
}
