Run two Microsoft Teams accounts on Mac
One instance per tenant, each signed in permanently and each with its own Dock icon — instead of switching organisations inside a single app.
7-day free trial · $19 once · macOS 13+ · notarized by Apple
What you get
- One instance per tenant. Each instance holds its own Teams account and organisation.
- Separate sessions. Cookies, storage and logins are isolated per instance.
- SSO logins just work. Sign-in links follow whichever instance you're using, so Microsoft's sign-in flow completes where you started it.
- Its own Dock icon. Colour-tinted per instance.
The new Teams ships on Microsoft's Chromium-based runtime, which MacDupl isolates well — but we haven't verified it hands-on, so we list it as “Should work”. The 7-day trial confirms it on your Mac in seconds.
- The new Teams ships on Microsoft's own Chromium-based runtime, the same tier MacDupl verified for Chrome.
- Sign-in callback links are routed to whichever Teams instance is frontmost, the same mechanism used for Zoom.
How to set it up
- Pick the app
Open MacDupl and choose Microsoft Teams from the list of apps installed on your Mac. - Name and colour it
Call it “Work”, “Personal” or a client's name, and give it one of nine icon tints. - Hit Create
About two seconds later there's a new Microsoft Teams in your Dock — sign into the second tenant — Teams keeps switching organisations to one click, not one app.
Questions about Microsoft Teams
Why not use Teams' built-in account switcher?
The switcher keeps one app and one session at a time. Instances give you two apps signed in at once, each with its own notifications and its own Dock icon.
Does this work with the classic Teams app?
MacDupl detects each app's engine rather than matching a list, so it applies whatever isolation strategy the installed build calls for. The trial tells you exactly how yours is classified.
Will meeting notifications double up?
Each instance notifies only for the account signed into it.
Is Microsoft Office cloneable too?
No. Office is a sandboxed App Store app — its data lives in a shared container a copy would still read, so MacDupl hides it rather than hand you a broken instance.
