Slack now has an Outlook Calendar app for Slack that will allow users to respond to meeting requests; be notified of any potential scheduling conflicts; and provide a link to Skype for Business, Webex or Zoom meetings scheduled via Outlook. The app also will allow users to automatically sinc their Outlook calendars with the Slack status and forward emails from their Outlook inboxes directly into any of their Slack channels or direct messages.
Slack also is updating its OneDrive app for Slack to make sharing and collaborating on files stored in OneDrive easier. Users also can locally preview Office files, like PowerPoint presentations or Word documents in Slack.
I asked Elliott whether Slack and Microsoft had collaborated to make these integrations happen. He said that Slack used the publicly available Microsoft application platform interfaces (APIs) and that Slack and Microsoft's Azure teams had talked about back-end integrations recently.
