Change all users' UPN using powershell

Hello All,

I need to change UPN suffix for all of my users.  I know that I can change one user's UPN using powershell and the Set-mailbox command.  I'm trying to figure out the syntax to do all users.  I wish there was a parameter for just the SUFFIX of the UPN, but I haven't found anything on that.  So, to change all users, I exported them to a csv file and corrected the UPN in that file.  I was going to run the following command to change the UPN, but I'm getting complaints about the the syntax.  

Import-csv c:\users.csv | Set-Mailbox -Identity $_.identity -UserPrincipalName $_.upn

Can someone give me some guidance?  Thanks so much.
