Install the add-in

Download the manifest, open My add-ins in Outlook and add it under Custom add-ins. Admins can deploy it to everyone from the Microsoft 365 admin center.

Save attachments

  1. In one folder, tick the emails you want (up to 100). With Conversation view on, expand a conversation and tick each email.
  2. Open AttachDrop from the ribbon or Apps. It counts the attachments and their size.
  3. Choose ZIP download or OneDrive folder, pick a naming rule and filters, then click Save.

Upgrade or manage billing

Open the AttachDrop pane in Outlook and use the Plan card at the top: Upgrade opens a secure Stripe checkout; Manage billing opens the Stripe customer portal for invoices, payment method, seats and cancellation.

Good to know

  • Multi-select works for up to 100 emails from one folder. On Mac, Outlook saves the attachments of the open email.
  • Inline images (such as signature logos) are skipped by default. Turn this off under Filters.
  • OneDrive links (cloud attachments) are listed in cloud-links.txt.
  • Very large ZIPs (over about 500 MB) are better saved to OneDrive.
