Organizations heavily depend on public folders for essential business operations due to their straightforward deployment and convenient content sharing capabilities.
Within Microsoft Exchange Server, multiple users can access public folders if they have appropriate permissions. Outlook users can share various information such as contacts, emails, templates, notes, calendar items, journal entries, and custom attributes within public folders.
When a new public folder is created in Exchange Server, it does not have an SMTP address. No one can directly send an email to it. To start the email service, Exchange administrators have to manually enable it.
You can mail enable or mail disable public folders in Exchange Server either from the Exchange Admin Center or using the Exchange Management Shell. Moving forward in this blog, we will see the steps for it. However, before we begin, let’s understand what are mail-enabled public folders in Exchange.
Mail enabled Public Folders in Exchange
Mail-enabling of public folders is a feature that allows users on the internet to send emails directly to that public folder. A mail-enabled public folder in Exchange is assigned an SMTP address to which anyone can send emails. This helps in developing a collaborative environment, centralizes email delivery for teams and departments, and simplifies information sharing among multiple users.
There are situations when you want to control mail flow to your public folder. In Exchange Server, administrators have the authority to modify the permissions or settings and mail-enable/disable a particular public folder.
Who can do it?
Not everyone has the authority to assign an email address to a public folder. You must have the following permissions:
- Organization Management
- Public Folder Management
Moreover, after mail-enabling the public folder, make sure to assign the CreateItems access right to the Anonymous account. If you don’t do it, outside users from Gmail, Yahoo, etc., domains will not be able to send emails to that particular public folder.
Mail enable or disable through Exchange Admin Center
To manage the mail settings directly from the Exchange Admin Center, use the following steps:
- Log in to EAC (Exchange Admin Center) with Exchange administrator credentials.
- Go to public folders and then select public folders. Select the public folder you want to set mail settings for. Under Mail settings, click on the Disable option for the mail enabled public folders in Exchange. In the reverse case, click the Enable option if it is already Disabled.

- A warning message is displayed. Select Yes to confirm the setting.

Hence, you will see the changes under Mail settings (the status has been changed to Disabled).
Mail enable or disable through Exchange Management Shell
Another way to manage the mail settings is via Exchange Management Shell. You can execute cmdlets to assign or remove the SMTP address for any public folder in Exchange.
- Open the Exchange Management Shell and run the given cmdlets:
- Run this cmdlet to mail disable public folders in Exchange:
Disable-MailPublicFolder -Identity “public-folder-name”

- Similarly, execute this command to mail enable public folder in the Exchange Server.
Enable-MailPublicFolder -Identity “public-folder-name”
Here, “public-folder-name” is the name of the public folder for which settings are performed. Executing the command will ask for confirmation. Enter “Y” to confirm the action. Thus, the public folder is now mail-disabled.
So, we’ve learned how to mail-enable or disable the public folders in Exchange. Both methods are viable options, with the Exchange Admin Center being the more straightforward choice, especially for those without extensive technical knowledge.
What to do if Public Folder content is inaccessible?
Using public folders in Exchange is common today. But what if these folders become corrupt or their content is inaccessible due to power outages, application interference, or hardware failures? Such a situation demands an urgent need for an Exchange data recovery solution.
However, the manual data recovery methods for Exchange servers are time-consuming and unreliable for today’s busy administrators. They require efficient software that can meet their requirements and deliver quick results. Kernel for EDB to PST Converter is an advanced solution that can recover mailbox from an EDB file, including inaccessible public folders. It provides selective recovery with smart data filters and saving options, such as Live Exchange, Outlook PST file, Office 365, etc.
