Enable Office 365 External Sharing

In this article we will have a look at enabling the office 365 external sharing option

Following services can be shared externally from your office 365 tenant.

1) SharePoint Sites.

2) Calendar free/busy sharing.

3) Lync – You can add people outiside your organizations , skype and  can communicate provided the following conditions are met.

Login to the office 365 portal with admin privilige

Click on Admin and click on external sharing

E1

Now we have external sharing options for 3 of the services

When we click on SharePoint we get the below option as shown below

Also we have an option to share individual site by selecting them and then it gives us the same option.

Once sharing is enabled, users can use Outlook Web App to share their calendars with anyone inside or outside the organization. People inside the organization can view the shared calendar side-by-side with their own. People outside the organization will be sent a URL that they can use to view the calendar. Users decide when to share, how much to share, and when to keep their calendars private

Note: If you want to share calendars with an organization that uses Exchange Server 2013 (an on-premises solution), the Exchange administrator will need to set up an authentication relationship with the cloud.

Below is the option that we have for enabling external sharing for lync

The organization you’re communicating with must also allow communication with your domain. If the other organization has Lync Server on premises, refer them to the TechNet article Configuring Federation Support for a Lync Online Customer.

When you’re communicating with someone in a federated domain, you can only use Lync features (for example, video conversations or desktop sharing) that are turned on in both organizations.

If the external access setting is changed from “On only for allowed domain” to “On except for blocked domain”, the domains that are listed won’t be kept.
