OutlookDogAdd OutlookDog to Outlook
OutlookDog runs on Outlook Classic (Windows), New Outlook, and Outlook on the web. It works with any Microsoft-hosted mailbox — a work/school Microsoft 365 account or a free personal account (outlook.com, hotmail, live). Mailboxes hosted elsewhere (Gmail, Yahoo, IMAP) can't run Outlook add-ins. The add-in's manifest lives at:
https://outlookdog.com/manifest.xml
Option 1 — Deploy it for your account or org (recommended)
Microsoft 365 admin center
Go to admin.microsoft.com →
Settings → Integrated apps → Upload custom apps → choose
Provide link to manifest file → paste
https://outlookdog.com/manifest.xml → assign it to yourself (or everyone) → Finish.
It can take a little while to appear (Microsoft says up to a few hours). Once it does, it shows up in all your Outlook clients — open a message → Apps → OutlookDog → Show Taskpane.
Option 2 — Sideload on a Windows PC you control (instant, for testing)
Classic Outlook for Windows
Save the manifest locally, then register it as a developer add-in (Command Prompt):
reg add "HKCU\Software\Microsoft\Office\16.0\WEF\Developer" /v OutlookDog /t REG_SZ /d "C:\path\to\manifest.xml" /f
Fully close and reopen Outlook, open a message, and look for OutlookDog on the Home ribbon (or under Apps). Requires a licensed desktop Office (Microsoft 365 Business Standard or similar) on a Microsoft 365 mailbox.
Option 3 — AppSource
Coming soon
One-click install from Microsoft AppSource is on the way. Until then, use Option 1 or 2 above.
