Requirements for Using Boxcryptor in Microsoft Teams

To use Boxcryptor for Microsoft Teams, you need the following:

  • A license for Microsoft Teams (Microsoft 365 Business Basic, Standard, or Office 365 E3)
  • A license for Boxcryptor Company or Enterprise
  • The “Boxcryptor for Microsoft Teams” app. Download here

Add the Boxcryptor App to Microsoft Teams

Step 1: Add the “Boxcryptor for Microsoft Teams” app.

Required role: Microsoft Teams administrator

The “Boxcryptor for Microsoft Teams” app needs to be added to your organization's app store in Microsoft Teams. To do this, download the Boxcryptor app package and then upload it to your Microsoft Teams tenant in the admin center.

Instructions on how to upload the app package can be found in the Microsoft documentation.

Step 2: Connect Boxcryptor and Microsoft Teams.

Required role: Boxcryptor administrator

If the Boxcryptor app is available in your Microsoft Teams main account, a Boxcryptor administrator must log in to the Boxcryptor app in Microsoft Teams once. This will connect your Boxcryptor organization to your Microsoft Teams account. After at least one Boxcryptor administrator has successfully logged into Boxcryptor in Microsoft Teams, Boxcryptor will be available for all of your users.

Step 3: Add the Boxcryptor app as a tab in the desired channel.

Encrypt Files in Microsoft Teams With Boxcryptor

After Boxcryptor has been successfully added to the team, files can be shared encrypted. There are several ways to do this:

1. Encrypted Upload of Files in Conversations in Microsoft Teams.

On the one hand, files can be shared with other team members via the chat function. To do this, a New conversation is started in the Posts tab.

After successfully uploading the file, the green lock next to the file name indicates that it is encrypted.

3. Encrypted Messages in Microsoft Teams Chat

New: Since November 2021, Boxcryptor can also encrypt text messages in Microsoft Teams. This enables the secure transfer of secret information (such as passwords) via text message.

The way to an encrypted text message is the same as the way to an encrypted file: Clicking on the Boxcryptor icon below the input field takes you to the editor for the message. This function is available for chats and for posts in channels.

For a detailed description of how to send encrypted text messages in Microsoft Teams, see our blog post „New: Encrypted Messages in Microsoft Teams“.

Grant Access to Encrypted Files

Boxcryptor automatically takes care of key and permission management so that all members of your channel have access to encrypted files. When Boxcryptor is added to a channel, all team members already assigned to the channel have access to the encrypted files. Others who open the Boxcryptor tab and do not yet have access can request access from the channel.

Clicking Request Access will automatically trigger a post to the posts section of the channel requesting access to Boxcryptor. Any person who already has permission to the folder can now “Grant Access”. Once this is done and the request is granted, the newly added person can now also access the encrypted files in plain text.
