connect tack to outlook and teams — your notifications, finally under control
when you connect microsoft 365, tack pulls in your work notifications and helps you triage them into now, next break, and tomorrow morning.
head to tack and click “sign in with microsoft”. use your work or school email — the one you use for outlook and teams.
you'll see a permissions screen. pick what you want tack to access:
you can always change these later in settings.
microsoft will ask you to confirm. click accept and you're done. tack will start syncing your notifications right away.
tack reads your outlook messages to show them in your triage view. when you mark something done or archive it, tack updates the message in outlook so everything stays in sync.
tack checks your calendar to see when you're in meetings. this way it can hold non-urgent stuff until you're free. we never modify your calendar — just read it.
tack pulls in your teams chats and mentions so you can triage them alongside email. we don't send messages on your behalf — just read them.
tack checks if you're in a call or marked as busy. when you are, it holds notifications until you're available again. urgent stuff still breaks through.
some companies lock down which apps can access microsoft 365. if you see “admin approval required” when trying to connect, here's what to do:
make sure you granted write email permission. if you didn't, head to settings and re-grant permissions.
confirm you granted teams messages permission. also check that your organization allows third-party apps to access teams.
tack encrypts your messages with your personal encryption key. only you can decrypt them — even tack admins can't read your stuff. learn more in our security whitepaper.
