Microsoft Teams has recently emerged as an indispensable tool in the online teaching activities of teachers, teachers can completely add members to their group easily by sending the group code or link. members or enter an email to invite to the group. But it would be much more complete if we could add a bunch of members to the group at the same time instead of having to choose each person like now, right? Don't worry, I have a way to help teachers do it easily. Let's follow the simple steps below.
Step 1: Prepare a list
Teachers need to prepare a list (excel) of email accounts that they want to add to their Group on Microsoft Teams. Microsoft Teams can also accept accounts that are different from the teacher's Teams account (eg Gmail, hotmail or any other type of email account).

Teachers only need to pay attention to the Email field, no other information fields are needed
Step 2: Add a semicolon (; ) at the end of each Email
This step is very important because when teachers copy this email list to MS Teams, each email in the list must be separated by a comma (; ), this step helps teachers not to add a comma (; ) to separate them manually.
Teachers should use the string concatenation formula in Excel (= A & B) to combine the Email string and the sign (; ) for fast

Copy recipes in bulk for other emails.

Again, teachers only need to pay attention to the Email field, other schools don't need it.
Step 3: Search for Addin for the browser
Teachers open the web browser Google Chrome (or Firefox) and Type the keyword Refined Microsoft Teams to search for Addin for the browser.

For Firefox browser, you will find it faster with the keyword Refined Microsoft Teams for Firefox

Step 4: Add Addin for Browser
Teachers click on the search results as I marked in to add the Addin to their browser.
Click Add too Chrome (similar Firefox)

Then will appear an Alert (warning) that: It can read and change your data in Microsoft Teams.

Teachers click Add extension then you will see the Refine MS Teams icon on the browser bar.

Step 5: Log in to MS Teams on the browser
Teachers just need to log in to their Teams account on Chrome or Firefox browser. Then you select a group that you want to add members to. Select the More Options icon (...) and select Add Member

A dialog box will then appear so that the teacher can add members to the group, but notice that the teacher will see one more box appear to help us add more members at the same time.

Step 6: Add members in bulk
Teachers go back to the email list file that we have prepared in step 2 and copy the email list in the Email column added (; ) at the end and paste it in the box you have framed in red above and click Bulk import to enter the pasted list into the teacher's group.

And microsoft Teams will automatically classify members and guests for teachers (emails that do not have the same domain name will be guests)

So teachers have added members to Microsoft Teams in bulk quickly, right?
Wish teachers will have interesting experiences with Microsoft Teams
