You can use either Outlook or Exchange Online PowerShell to set permissions on a public folder’s Anonymous account. You can’t use the EAC to set permissions on the Anonymous account.
Use Outlook to set permissions for the Anonymous account
- Open Outlook using an account that’s been granted Owner permissions on the email-enabled public folder you want anonymous users to send mail to.
- Navigate to Public folders – <user’s name>.
- Navigate to the public folder you want to change.
- Right-click on the public folder, click Properties and then select the Permissions tab.
- Select the Anonymous account, select Create items under Write, and then click OK.
Use Exchange Online PowerShell to set permissions for the Anonymous account
This example sets the CreateItems permission for the Anonymous account on the “Customer Feedback” mail-enabled public folder.
