In certain environments, installing the Teams app might not be possible, not even by the team owner. There are two ways to enable the app anyway, though an approval of a Microsoft Teams administrator will be required.
Allow team owners to install apps by themselves
This is the option Microsoft recommends - and also on by default.
In case your administrator has disabled this option, it’s possible to turn this back on. To do this, please (as an Office 365 administrator) go to the following page in the AzureAD portal (Enterprise applications > Consent & Permissions):
The option “Group owner consent for apps accessing data” needs to be allowed. This will allow team owners to install the app.
In addition to this setting, please also make sure that installing third party apps is allowed by the applicable app permission policy here:
Choose the policy that is assigned to your Jira users in Teams (or if you just have the global one, choose this).
Then make sure that third-party apps are allowed - or just allow the installation for our app “Smart Connect for Jira”.
Please note: it may take up to 24 hours for the app to be visible for users in Teams.
Install the app for certain teams manually
In case it’s not possible to turn on the above options, Microsoft Teams administrators can also add apps on a case by case basis.
To do this, please send your administrator to the following page:
Search for the “Smart Connect for Jira” app, and add it to the requested team using the “Add to team” button. In case the app is not allowed by default, it might also be necessary to allow the app first.
Please note, in case you see this error below, it usually still worked correctly, and the app should be installed. There currently seems to be a bug on the Microsoft side regarding this.
