Before you start to delete folders in Exchange Online
Follow the steps carefully, as shown in the article to:
- Delete specific folder/folders from specific mailboxes in Exchange Online
- Delete specific folder/folders from all mailboxes in Exchange Online
Add impersonation rights in Exchange Online
Use impersonation when you have a service application that needs to access multiple mailboxes and “act as” the mailbox owner. Read more about impersonation and EWS in Exchange.
Create and add impersonation rights to the account that is going to run the script. It can be a global admin account or a service account. In our example, the global admin account is added.
Log in to Exchange Admin Center (Exchange Online). In the feature pane, click on permissions and follow with admin roles in the tabs. Click the + icon in the toolbar to create a new role group.
Give the new role group a name — for example, Application-Impersonation. Assign the role of Application-Impersonation. Add yourself, the global admin, or a service account that you created as a member. Click Save when done.
The role group Application-Impersonation is created successfully. Good to know is that it can take up to an hour before the changes are applied.
The next step is to install Microsoft Exchange Web Services Managed API 2.2.
Microsoft Exchange Web Services Managed API 2.2
Download and install Microsoft Exchange Web Services Managed API 2.2. Download from here (Microsoft) or here (direct link). Save the file to the system.
Run the setup as administrator and install Microsoft Exchange Web Services Managed API 2.2.
After installing, verify in the installation path that you can see the files.
The next step is to create the text files.
Create text files for the script
Create three text files in the C:\Temp folder.
- Folders.txt
- Log.txt
- Users.txt
Open Folders.txt and add FolderName at the top. Add the folder names on each line. In our example, we like to delete four folders in the mailboxes.
The script will generate logs and place them in the Log.txt file. Keep it empty.
Open Users.txt and add EmailAddress in the top. Add the email addresses on each line. The script will delete the folders from these mailboxes.

The next step is to edit the script if needed.
Edit the Delete Folders Exchange Online PowerShell script
The script will delete the folders completely, and you can’t recover them from deleted items. Do you want to delete the folders to the mailbox Deleted Items folder?
Check lines 82, 83, and 84 for the available options. Change it to your needs.
The script will target the mailboxes specified in the Users.txt file. Do you want to target all the mailboxes?
Change line 106 from Import-Csv $FoldersCSV -Encoding UTF8 | Foreach-Object { to Get-Mailbox -ResultSize Unlimited | Foreach-Object {
The next step is to install and connect to Exchange Online.
Connect to Exchange Online PowerShell v2
Start Windows PowerShell or Windows PowerShell ISE as administrator. Install Exchange Online PowerShell v2 and connect to Exchange Online.
Important: If you have MFA enabled on that account, disable it.

PS C:\> Connect-ExchangeOnline -UserPrincipalName admin@exoip.com |
The next and last step is to run the script.
Run the Delete Folders Exchange Online PowerShell script
In our example, we do know that user James got all the folders in his mailbox.
Before running the script
- Subfolder Folder Audio
- Subfolder Folder Pictures
- Folder Folder Music
- Folder Folder Videos
Change the directory to the scripts folder and run the script. A credential prompt will show up. Enter your global admin account or service account that is a member of the application impersonation role.
It starts searching for the folders in the mailboxes. The output will write to the Log.txt file.

Rerun the script. It will show that there is nothing to delete.
