TENANT ADMIN Actions on this page require global tenant administrator rights. 

To update an existing Nimbus app (e.g. with a new manifest):


  1. Login to MS Teams as Tenant Admin
  2. Go to Apps
  3. Select the "Built for Luware Inc." option and identify your existing Nimbus App entry.
  4. Click the three dots icon (context menu) in the top right corner of the application
  5. Select Update in the drop-down menu

  6. Select the new manifest zip archive in the window.

Manifest upload steps

Upload app manifest

For Nimbus to be available in your Tenant (to allow your users to install it from MS Teams Apps list) manifest needs to be uploaded first. 


  1. Retrieve the Nimbus manifest Zip from Luware. Your Nimbus onboarding team will provide you with a download link.
    (lightbulb) You can have a look inside, but you don't need to unzip the archive for the next steps.


  2. Login to MS Teams as Tenant Admin

    1. Go to Apps
    2. Select “Upload a custom app” option

      Choose “Upload for <Your_Organization_Name>” option from the opened drop-down menu

    3. Select and upload the Nimbus manifest → A message "Added Luware Nimbus to the list" should confirm the successful upload.

  3. Confirm the App's entry and new version within the "Manage Apps" Screen.
    (info) Also read on how to update an existing app further below.

    Luware Nimbus successfully added to the Teams Apps
  4. Go to "Apps" in your Teams client front end and search for "Nimbus" → The  Nimbus  app entry should now appear in the list of Apps for all users in your Tenant.

Check the permission policies and external access

  1. Go to Teams Apps > Permission Policies > Global (Org-wide default) 
  2. Check the setup for "Custom Apps" → This must be set to either "Allow all apps" or "Allow Specific apps"
    (lightbulb) If this does not, please amend to one of above. Depending on Microsoft you might have to wait 24 hours before continuing with the next steps.
  3. Go to Users  > External access
  4. Allow either "all external domains" or "specific external domains"
