Let's Create a Slack and Outlook Integration Flow

Let's get started by creating a flow that integrates Slack and Outlook! This time, we'll use Yoom to proceed with the integration of Slack and Outlook without any coding. If you don't have a Yoom account yet, please create one using the registration form here.

[What is Yoom]

In this session, we will create a flow that integrates data into Outlook when a specific message is received in Slack!
The creation process is broadly divided into the following steps.

  • Integrate Slack and Outlook with My Apps
  • Copy the template
  • Set up Slack triggers and Outlook actions
  • Turn on the trigger and check the operation

Step 1: Connect Slack and Outlook with My Apps

First, let's connect Slack and Outlook with My Apps.
After logging into Yoom, click "New Connection" from "My Apps" in the left menu.

[For Slack]

1. Search for "Slack" and select Slack from the list of apps.

2. Sign in to the Slack account you want to connect with Yoom. Then, configure the following settings:

  • Workspace you want to connect (selectable from the dropdown at the top right)
  • Channels within the workspace

After completing the settings, click "Allow".

If administrator approval is required, please refer to the help page.

This completes the My Apps connection for Slack.

[For Outlook]

Note: Microsoft365 (formerly Office365) has plans for home use and general business use (Microsoft365 Business). If you are not subscribed to the general business plan, authentication may fail.

1. Search for "Outlook" and select Outlook from the list of apps.

2. Enter the email address of the Microsoft account you want to connect with Yoom.

3. Enter the password.

This completes the My Apps connection for Outlook.

For the registration procedure and precautions for My Apps in Microsoft365 services, please also refer to this page.

Step 2: Copy the Template

Once the My Apps connection is complete, let's quickly set up the template.
Click "Try it" on the banner below to copy the template.

When the template is copied to Yoom, the following screen will appear, so press "OK".

Step 3: Set Slack Trigger

(1) Click on "When a new message is posted in the channel" at the top of the template.

(2) Enter the account information of the Slack you want to integrate with and click "Next".
The information of the account you integrated with is automatically entered by default.

(3) Configure Slack's [API Connection Settings].

Select thetrigger interval will be activated from 5 minutes, 10 minutes, 15 minutes, 30 minutes, or 60 minutes.
※ The activation interval varies depending on the plan, so please be careful.

(4) Set the channel ID where the messages that will trigger the flowbot will be received in "Channel ID".
A list of channel IDs in the integrated Slack will be displayed under "Optiomns".

Select the channel ID you want to set in the flow.

Once the settings are complete, send a message on Slack and click "Test" to conduct a test.
If the test is successful, click "Save" to complete the settings.

Step 4: Set Branching

(1) Click on "Command Operation" in the template.

(2) It is automatically set, but confirm that the following contents are set.

  • Title: Set as desired (default is "Command Operation")
  • Operation: Select "When a new message is posted in the channel"
  • Retrieved value: Select "Message Text"

※ Branching is a feature available in plans above the mini plan. If you are on a free plan, the operation of the flowbot you set will result in an error, so please be careful. During the free trial, branching settings are possible.

(3) Set the conditions for the branching process in "Branch Condition".
For example, if you set "Equal to" and "Issue", the branching process will only occur if the word "Issue" is included in the message body of Slack.

  • "Equal to" section: Can be set arbitrarily from the dropdown
  • "Example: Issue" section: Can set any message that will be the target of branching

Additionally, by clicking "+ Add Another Condition", you can set up to 5 branching conditions.

Please set it according to your business needs.

Once the settings are complete, click "Save" to complete the settings.

Step 5: Set to Send Email with Outlook

(1) Click on "Send Email" in the template.

(2) Select the account information to integrate.

(3) Set the Email cContent.

  • TO: Set the email address to be notified
  • CC/BCC: Set email addresses to be notified other than To
  • Subject: Set the subject of the notification as desired
  • Body: Set the content of the notification as desired (can quote message text or user ID from "Retrieved value")

(4) Confirm the content of the email to be sent.
If there are no issues, try executing "Test".

In practice, the obtained output will be reflected in the email body.

If the test is successful, the settings are complete.

Step 6: Turn on the Trigger and Check Operation

With this, all settings are complete.
Once the settings are complete, a pop-up like the one below will be displayed, so turn on the trigger.
Check to see if the flow operates correctly!
