How can i sync contacts of our general mailbox account used in Office Web App (Office365)?

Question

Hello,
it would be comfortable to share contacts and calenders from Office365 using an iPhone.
My local Apple Adressbook is able to show and sync the contacts by setting up an Exchange-account for these general mailbox we created.
Using the same contact details my iPhone does not show any adress. There is only one fragment coming along - the empty Global Adresslist.
Calenders are similar. Local iCal shows others calenders by setting up a "representation" in the account details.
There is no way to get this displayed on iPhone too.
Is there anybody having a solution?
Regards,
Renate

Okay I think I figured it out. After I import the contacts with: import-contactlist -csv -csvdata ([system.io.file]::readallbytes("PATH TO CSV")) -identity USER
I can run this to find and delete each added contact: 
$tcontacts = get-content PATH TO CSV WITH ONLY NAMES
$zcontacts = get-content PATH TO CSV WITH NAMES OF MAILBOXES YOU WANT TO REMOVE CONTACTS FROM
$ccontacts = "null"
$scontacts = "null"
$xcontacts = "null"
foreach ($ccontacts in $tcontacts) {foreach ($scontacts in $zcontacts) {$xcontacts = $scontacts; Search-Mailbox -identity $xcontacts -SearchQuery kind:'contacts', $ccontacts -deletecontent -force}}
I use xcontacts = scontacts because of pointer issues (i think?) but anyway, using
$scontacts for the -identity doesnt work.
This is a pretty rough script, and you guys could probably find a shorter one, but it works! Thanks
