Paramant for Outlook — encrypted attachments from within your inbox.
The Paramant Outlook add-in lets you upload a file and insert a burn-on-read link directly from a compose or reply window in Outlook for Microsoft 365, Outlook on the web, and Exchange 2019.
Compatibility
- Outlook for Microsoft 365 — desktop app on Windows and Mac
- Outlook on the web — outlook.office.com and outlook.office365.com
- Exchange Server 2019 — on-premises, with Outlook 2019 desktop client
- Outlook 2016 / 2013 — Office.js add-ins require Outlook 2019 or 365
- Outlook mobile (iOS / Android) — add-ins are not supported in mobile Outlook
Installation
Add from Microsoft AppSource
In Outlook, open any compose or reply window. Click the Apps button in the ribbon (or the three-dot menu on web). Select Get Add-ins. Search for Paramant and click Add.
Alternatively, your Microsoft 365 administrator can deploy the add-in to your entire organisation from the Microsoft 365 admin center under Settings → Integrated apps.
Open the Paramant task pane
After installation, open a compose window. A Paramant button appears in the ribbon under the Message tab. Click it to open the task pane on the right side of the window.
If you don't see the Paramant button, close and reopen Outlook. On Outlook for the web, hard-refresh the page (Ctrl+Shift+R).
Enter your API key
The task pane shows an API key field on first run. Paste your Paramant API key and click Save. The key is stored in the add-in's local settings — it is not shared with Microsoft or stored on their servers.
Your API key is in Paramant Dashboard → API keys. If you don't have one, generate one there.
Sending a file
Open the task pane and select a file
With a compose window open, click Paramant in the ribbon to open the task pane. Click Choose file and select the file you want to send. A progress bar appears during upload.
Set expiry and click Send
Choose how long the link should remain active (1 hour to 7 days). Click Upload and insert link. The task pane inserts a formatted line into your email body with the secure download URL.
Send your email normally
The Paramant link is now in the email body. Edit surrounding text if needed, then send. Your recipient clicks the link, downloads the file once, and the link and file are deleted.
Organisation-wide deployment
Microsoft 365 administrators can push the add-in to all users without requiring individual installation. In the Microsoft 365 admin center: Settings → Integrated apps → Get apps, search for Paramant, and deploy to specific users, groups, or the entire organisation.
Users receive the add-in on next Outlook restart. API keys must be configured individually by each user unless your organisation provides a shared key via a managed deployment.
Do not use a single shared API key across all users in a large organisation — transfers from all users will appear under one account, and revoking the shared key will lock everyone out simultaneously. Use per-user or per-team keys.
