powershell combine two commands one output

I am trying to build this script but getting the following error message and it is processing everything not just the contents in the csv file




WARNING: By default, only the first 1000 items are returned. Use the ResultSize parameter to specify the number of
items returned. To return all items, specify "-ResultSize Unlimited". Be aware that, depending on the actual number of
items, returning all items can take a long time and consume a large amount of memory. Also, we don't recommend storing
the results in a variable. Instead, pipe the results to another task or script to perform batch changes.Cannot bind argument to parameter 'Identity' because it is null.

At First look, you need to change the following lines..

Change $_ to $user

$mb = get-mailbox -id $user | select displayname, alias, database, RecipientTypeDetails, primarysmtpaddress, identity,IssueWarningQuota, ProhibitSendQuota, UseDatabaseQuotaDefaults, SingleItemRecoveryEnabled
       
        $mbxstats = Get-Mailboxstatistics -id $user | select DisplayName.............

.........
.........

$fldstats = Get-Mailboxfolderstatistics -id $user |

Open in new window

Also c:\listofusers.csv should be without header..
UserA
UserB
UserC
