not trying to access via OWA. trying to open with normal 2010 outlook. And mailbox is also added. Till one day before there was items in mailbox next day user noticed there is no mails in that mailbox, it is disappeared so it means mails are deleted from mailbox. so i want to recover deleted mails. if i try to click on recover deleted mail the icon is grey out. So i have one question can i make this shared mailbox as a primary? if yes then how to make primary? then how to make user mail account secondary. kindly advice.
