Manage Mobile Phones via OWA is missing

Good day all -

Have a slight issue and was wondering if someone out there may have a suggestion. Currently cannot access the Mobile Phones option under OWA. Steps I am trying to do are listed below. Running an Exchange 2010 Version 14.03.0181.006. Do have a phone configured for ActiveSync and can successfully manage phone via EMC. Just cannot manage phone via OWA. Want to be able to give end user rights to (in case of lost phone). Under Organization Configuration/Client Access/Outlook Web App Mailbox Policies - Default is all set to Enabled. Have selected Private Computer Option as well via IE. Chrome but still no tab.

1.               OpenOutlook Web Access.
2.               Log on to the phone owner's mailbox.
3.               ClickOptions.
4.               In the Navigation pane, selectMobile Phones.
5.               Select the ID of the phone that you want to wipe and remove from the list.
6.               ClickWipe all data from device.
7.               ClickOK.
8.               ClickRemove device from list.

Thank you for your suggestions.
