Hi MSB,
For this kind of Outlook 2013 client issue, I’d like to involve our Outlook exports in dealing with it. I notice that you’re using Office 365 Home Premium. Actually, we have another dedicated support channel regarding Office 365 Home Premium questions.
Therefore, I recommend you try asking it in the following community staffed by specialists for Outlook and Office 365 Home Premium. I appreciate your understanding.
Office 365 Home Premium forum: http://answers.microsoft.com/en-us/office/forum/office_365hp?tab=Threads
In order that the query is addressed quickly, it’ll be nice if you can provide more details about this issue. For instance, what does “not available” mean? Does it mean the option is grayed out or an error message when you click on it? Hope you reach a resolution soon and you’ll be welcome to share it with this community members.
Thanks,
Maggie Li
