arrays - I keep getting the error "the specified string is not in the form required for an email address" when using Send-MailMessage -

#get max password age policy $maxpwdage=(get-addefaultdomainpasswordpolicy).maxpasswordage.days  #expiring in 7 days $7days=(get-date).adddays(7-$maxpwdage).toshortdatestring()  $emaillist = get-aduser -filter {enabled -eq $true -and passwordneverexpires -eq $false -and passwordlastset -gt 0} –properties * |              {($_.passwordlastset).toshortdatestring() -le $7days} |              select-object emailaddress  $emailfrom = "code.example@email.com" $emailcc = "code.example2@email.com"  $emailsubject = "example subject"  $emailbody = "example body" $smtpserver = "192.168.8.130"  foreach ($element in $emaillist) {   $output = out-string -inputobject $element ;   if ($finaloutput=$output.contains(".")) {     send-mailmessage -smtpserver $smtpserver -from $emailfrom -to $output -cc $emailcc -subject $emailsubject -body $emailbody -bodyashtml;   } } 

the first several lines run fine, however, when foreach starts errors out , says

the specified string not in form required email address.

i unsure why error, because have converted $element string using out-string.

$element not email address, object happens have property called emailaddress.

out-string results in multi-line string console output of $element| format-table.

don't use out-string, refer emailaddress property directly:

$output = $element.emailaddress 

or, use -as cast address mailaddress object. if type check fails inside if() statement, send-mailmessage isn't executed.

if(($to = $element.emailaddress -as [mailaddress])) {     send-mailmessage -to $to } 

---

to avoid send-mailmessage line getting long, use splatting table:

$mailparams = @{     "from" = "code.example@email.com"     "cc"   = "code.example2@email.com"      "subject" = "raw intelligence!"     "body"    = "howdy! here datez n stuff"      "smtpserver" = "192.168.8.130" } 

and inside loop:

send-mailmessage -to $to @mailparams
