Create a public folder in Exchange Online
Public folders are designed for shared access and provide an easy and effective way to collect, organize, and share information with other people in your workgroup or organization.
By default, a public folder inherits the settings of its parent folder, including the permissions settings.
For more information about the storage quotas and limits for public folders in Exchange Online, see Exchange Online Limits.

Use the EAC to create a public folder
When using the EAC to create a public folder, you'll only be able to set the name and the path of the public folder. To configure additional settings, you'll need to edit the public folder after it's created.
Navigate to Public folders > Public folders.
If you want to create this public folder as a child of an existing public folder, click the existing public folder in the list view. If you want to create a top-level public folder, skip this step.
Click New .
In Public Folder, type the name of the public folder.
Don't use a backslash ( \ ) in the name when creating a public folder.
In the Path box, verify the path to the public folder. If this isn't the desired path, click Cancel and follow Step 2 of this procedure.
Use Exchange Online PowerShell to create a public folder
This example creates a public folder named Reports in the path Marketing\2013.
New-PublicFolder -Name Reports -Path \Marketing\2013
Don't use a backslash (\) in the name when creating a public folder.
For detailed syntax and parameter information, see New-PublicFolder.

In Exchange Online PowerShell, run any of the following commands:
Get-PublicFolder -Identity \Marketing\2013\Reports | Format-List
Get-PublicFolder -Identity \Marketing\2013 -GetChildren
