I’m trying to get a list of all events in my Outlook calendar. However when trying to use /me/events, I’m not receiving any events back.

I can however list all my calendars with /me/calendars. I can also list all the events in one of the public holidays calendar with /me/calendars/{CALENDAR_ID}/events, but when I try to do the same with my personal calendar I’m not getting anything back.

During the OAuth flow I’ve requested all permissions: Calendars.ReadBasic Calendars.Read Calendars.ReadWrite.

await msftClient.api('/me/events').get()
{
    '@odata.context': "https://graph.microsoft.com/v1.0/$metadata#users('[email protected]')/events",
    value: []
}

await msftClient.api('/me/calendars').get()
{
    '@odata.context': "https://graph.microsoft.com/v1.0/$metadata#users('outlook_1338A354C5FA734F%40outlook.com')/calendars",
    value: [
         {
            id: '1234',
            name: 'Calendar',
            ....
        },
        {
            id: '5678',
            name: 'United States holidays',
            ....
        }
    ]
}

await msftClient.api('/me/calendars/1234/events').get()
{
    '@odata.context': "https://graph.microsoft.com/v1.0/$metadata#users('[email protected]')/calendars('12345')/events",
    value: []
}

await msftClient.api('/me/calendars/5678/events').get()
{
    '@odata.context': "https://graph.microsoft.com/v1.0/$metadata#users('[email protected]')/calendars('5678')/events",
    value: [
        {},
        {},
        {}
    ]
}
