What our analysis found

Save Outlook Emails as PDF by cloudHQ showed no malicious code in Extension Auditor's review. It was last updated in October 2026.

Analyst notes

All outbound network requests are gated to [domain withheld]: the PROXY_AJAX service-worker handler (:9919) explicitly validates `url.startsWith('[domain withheld]')` before forwarding any request, and the only [domain withheld] and [domain withheld] calls are for the PDF-conversion pipeline that is the extension's stated purpose. The intercepts Outlook OWA API responses () solely to extract email item IDs and subjects needed to identify which emails to convert — this is standard practice for Outlook add-ins and the extracted data is passed via postMessage to the content script, never exfiltrated to a third party. The ML score is driven by permhash cluster contamination (30% of 615 peers are malware that happen to need the same Outlook + storage + background combo), not by any malicious behavior in this extension's actual code; chrome-stats's 'trusted-publisher' signal and cloudHQ's Google Trusted Publisher badge corroborate the benign verdict.

About this extension

Save Outlook emails as PDF, HTML, TXT, or EML — with attachments included.

Read the publisher’s full description

Save and back up your Microsoft Outlook emails as PDF (or HTML, TXT, or EML) with a single click. The extension adds a "Save to PDF" button to the Outlook ribbon (Home tab) on Outlook.com, Outlook on the Web, and Microsoft 365 Outlook. Works on personal Outlook accounts (outlook.com, hotmail.com, live.com) and Microsoft 365 / Office 365 work accounts. WHAT IT DOES 📄 Save individual emails as PDF: select any message in Outlook and click Save to PDF. Done. 📦 Save many emails at once: select 5, 50, or 5,000 emails and download the whole batch as a ZIP of PDFs. 📚 Save entire folders: back up your Inbox, Sent Items, or any custom folder (and all subfolders) using the dashboard wizard. Full subfolder structure is preserved in the resulting ZIP. 🧵 Conversation-aware: when Outlook is in conversation view, the whole conversation is saved as one PDF. Switch to flat view and each message saves separately. 🔁 Merge or keep separate: choose "one PDF per email" or "merge everything into one PDF." 📎 Attachments included: embed every attached doc, image, and PDF inside the output PDF, OR package them in a separate ZIP – your choice. 🔐 Encrypt with a password: generate password-protected PDFs for sensitive correspondence. 📑 Multiple output formats: PDF, HTML, TXT, or EML. Mix and match per export. HOW IT WORKS 1. Install the extension. 2. Open Outlook on the web (outlook.live.com, outlook.office.com, or outlook.office365.com). 3. Select one or more emails. 4. Click the "Save to PDF" button in the toolbar. 5. Pick your options (format, merge, attachments, password) and click "Start conversion." 6. Get a download link by email when the file is ready, or stay on the dashboard and grab it as soon as it lands. For a full mailbox backup, click the cloudHQ icon in the Chrome toolbar, then choose "Start the Wizard". That flow lets you pick a folder (or your entire account) and get a zip of every email in PDF, HTML, TXT, or EML format, neatly mirroring your folder hierarchy. PERFECT FOR: ⚖️ Lawyers: package every email related to a litigation, conversation, or client into one PDF you can hand to courts, opposing counsel, or your firm's case-management system. 🏢 Compliance and legal hold: archive sensitive correspondence in a court-friendly format (PDF), with attachments and metadata preserved. 📂 Project archiving: save all email related to a project before closing it out, instead of leaving it scattered across your mailbox. 🎓 Students and academics: keep a permanent copy of important threads with professors, advisors, or coauthors. 🚪 Leaving a job: back up personal correspondence before your work account is deactivated. 💼 Small business: keep a hard-drive backup of your entire mailbox for record-keeping, tax season, or peace of mind. PRIVACY AND SECURITY, YOUR DATA IS YOURS: • Your emails never leave Microsoft and cloudHQ. We don't share your data with advertisers or third parties. • We don't store your emails after the conversion is done. • You can revoke access at any time from your Microsoft account or by uninstalling the extension. • Support article: How cloudHQ handles your data: https://support.cloudhq.net/category/security/ cloudHQ.
