Should I choose Atrium or Outlook Calendar?

AppRanks cannot recommend one over the other from published marketplace data: the Slack Marketplace does not expose a rating or review base that separates them. Read both apps' detail pages for the feature breakdown, and compare against your own requirements rather than a headline number.

Which is faster to set up, Atrium or Outlook Calendar?

Both apps are one-click installs from the Slack Marketplace. AppRanks doesn't measure setup time directly, and the Slack Marketplace publishes no review base that would let us infer it for these two — read the recent reviews on each app's detail page for user-reported install experience.

Which works better for small vs large Slack Marketplace teams?

Atrium typically suits early-stage and growth-mode teams based on its published review base (0 reviews). Outlook Calendar typically suits early-stage and growth-mode teams based on its published review base (0 reviews). A larger review base generally means the app has been exercised at scale — relevant if you are processing high volume or handling enterprise compliance requirements.

Can I migrate data between Atrium and Outlook Calendar?

Migration support varies by app and category. Atrium and Outlook Calendar both publish their export options on their marketplace listing pages (or in their support docs); some apps offer one-click import from competitors, others require CSV. The fastest check: search "import from Outlook Calendar" in each app's help center. AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.

Outlook Calendar

Let your team know when you're busy and keep your calendar top of mind with up-to-date reminders in Slack. Available for Office 365 Outlook Calendar. Use Outlook Calendar in Slack to: • Automatically sync your calendar to your Slack status to let your team know when you are in a meeting, out of the office, or working from home. • See a holistic view of your daily schedule from Slack. • Get notified when an event is starting soon, and join a Hangout, Zoom, Webex, or Microsoft Teams meeting directly from the calendar reminder in Slack. • RSVP directly to event invitations, get updated when an event’s details change, and change your response as needed. • Configure channel notifications for shared calendar events. Here are some details to bear in mind about status sync: • Your status will not include the name of the meeting that you’re attending. • You can remove or update your Slack status at any time – the Outlook Calendar app won’t override any status that you’ve set yourself. • Only events that you accept will trigger a status update in Slack. • Slack will only sync with the primary calendar for the Outlook account that you’ve connected. • If there are overlapping events on your calendar, Slack will set your status to match the event that’s longer or that starts earlier. Notes: • Outlook Calendar for Slack is only available for Office 365. The app is not supported for on-premise Microsoft Exchange customers. • On-premise SharePoint installations or Office 365 plans hosted on a Microsoft national cloud deployment (including Office 365 U.S. Government, Office 365 Germany, and Office 365 operated by 21Vianet in China) are not supported.
