A pretty dumb application to delete all possible shared permissions on your work Outlook calendars.

Select + New Registation and create a new registration
- Ensure that Accounts in this organizational directory only (University College London only - Single tenant) is selected
- For the redirect URI select Public client/native (mobile & desktop) and enter https://login.microsoftonline.com/common/oauth2/nativeclient for the URL
- Click Register
Note down the Application (client) ID value and Directory (tenant) ID value in the redirect page
The redirect page will have a Client Credentials in the table: click Add a certificate or secret
- Add a new secret with a sensible name and expiration date, noting down the secret value
On the left hand side of the main page click on the API permissions
- Click on + Add a permission and select Microsoft Graph
- Select Delegated Permissions
- In the Select Permissions search box, enter Calendars
- From the permission table below, expand Calendars and tick Calendars.ReadWrite
- Then select Add permissions

Configure local application

Clone and install the repository

git clone git@github.com:stefpiatek/calendar_bouncer.git
cd calendar_bouncer
pip install -e .

Copy and the secret credentials and replace dummy values with those noted down from the previous steps, along with your work email and password
```
cp example.secrets.toml .secrets.toml
# Now edit the file
```
If you haven't run the application before, run it from the command line so that it will generate a URL for you to consent to the application carrying out delegated calendar actions for you
```
calendar_bouncer
```
Click on the link in the STD out, logging in and accepting the permissions (redirect is expected to be a blank page)
The application should now be able to run from the CLI successfully
