Can I attach files when adding comments to a Case in the Partner Portal?

Yes. While adding a comment to a case in the Partner Portal, you can attach supporting files or images to provide additional context. This helps the support team or CRM users resolve the case faster.
Supported file types include:

• PDF
• XLSX / Sheets
• Microsoft Word / DOCX
• JPEG / Images
• Other common document formats

Comments with attachments are visible to the assigned person in the CRM and Partner Portal. If you use Post Comment to Portal, the comment and attachments will be visible across all platforms: CRM, Customer Portal, and Partner Portal.
