In my previous blog we have already gone through, how to create a site collection using PowerShell. Now we have a site collection with us and we will now create a site ( SPWeb) under the site collection using UI.
Find the following steps to create a sub site.
Step 1: Login to your admin account O365 and select site collection in which we are going to create a site.
Step 2: Navigate to the site, where we want to create the sub site.
Step 3: Click “Site Contents” from Site Action menu of the site. In Site Contents page, there are two different sections. One section contains information about available lists, libraries and option to "create a new app" and other one is "new subsite". Click on the "new subsite" link and open sit creation form.
Step 4: Provide all information’s that required in the site creation e.g. Title, URL, Site Template, etc.
Step 5: After all required information, click Create button to create the site.
