Add one or more attachments to a request by dragging files onto the attachment box or by selecting Select Attachment to browse your computer.

Before you begin
- Is the attachment action enabled on the service? The attachment action is enabled or disabled per request type under Service Configuration. If you don’t see the attachment action, the service owner may have disabled it.
- What is the maximum file size? The default maximum file size is 10 MB. An administrator can change this. If you upload a file that exceeds the limit, an error shows the allowed size.
Add a comment
Use the Add a comment field to explain the attachment or why you added it. The comment appears in the request timeline.
Select attachment
You can browse your computer or drag and drop one or more files onto the attachment area.
Tip
Hold Shift while selecting files to add multiple items at once.
Add a description
After you add files, enter a short description for each attachment. The description appears in the Attachments section of the request.
Select visibility
For each attachment, set visibility to Customer or Team. When visibility is Customer, the customer can view and download the attachment in the Employee or Customer portals. When visibility is Team or Owner, the customer cannot see the attachment.
Lock and unlock
Users with a Full Access role for the request type can lock this action. Locking prevents other users from uploading attachments. You can also control locking through Access Control in a workflow.
Attachment section
Open the Attachments section to access attachments added to the request. The section is visible only when one or more attachments exist.

Downloading
Click an attachment name to download it. Browser settings control download location and behavior.
Image preview
If the attachment is an image, an image icon appears next to its name. Click the icon to open a thumbnail, and click the thumbnail for a larger preview.
Actions
Use the Actions menu for each attachment to:
- Edit description
- Edit visibility
- Remove (permanently delete)
