Dear Young Yang,
Thank you for your reply.
I do mean one license of Office 365 Small Business Premium
With ´outside 365´ I mean that user 2 can use his emailaccount on an existing version of Outlook which is already installed on the desktop.
For example with Outlook 2003 or 2007. But then with the accountname created in Office 365. (like user2@company.com)
The user doesn´t need Word, Excel but just Outlook
Thanks,
Frits
