I would like to ask you for an help related to the reading my callendar events from MS Exchange by MS Graph API.
Issue: My code do not “download” the recurring Events from calendar, all others are downloaded.
Note:
- Im successfully authenticated OAuth2 –> so this code is not listed here
- Code it self is called from another cade so variables are hand over. I use this for testing:
- Filter_Start_Date = “2024-12-11”
- Filter_End_Date = “2024-12-11”
My code:
# Update filters)
Filter_Start_Date = Filter_Start_Date + "T00:00:00Z"
Filter_End_Date = Filter_End_Date + "T00:00:00Z"
headers = {
"Authorization": f"Bearer {access_token}",
"Content-Type": "application/json",
"Prefer": 'outlook.timezone="Europe/Paris"'}
params = {
"$filter": f"start/dateTime ge '{Filter_Start_Date}' and end/dateTime le '{Filter_End_Date}'", #! To be done --> maybe here is some issue with filtering data !!!!
"$orderby": f"start/dateTime desc",
"$top": 1000,
"$count": "true",
"$select": "subject, start, end, categories, recurrence, showAs, location, isAllDay, bodyPreview"}
Events_downloaded = {}
events_url = f"https://graph.microsoft.com/v1.0/users/{username}/events"
events_response = requests.get(url=events_url, headers=headers, params=params)
Counter = 0
if response.status_code == 200:
# Init page
Events = events_response.json()
Can anyone tell me what do I do wrong?
Thank you

For sample, I created a recurring event using Microsoft Graph API:
To read the recurring events make use of below code:
access_token = "AccessToken"
username = "[email protected]"
# Define start and end date for filtering events (adjust these dates based on your needs)
Filter_Start_Date = "2024-12-12T00:00:00Z"
Filter_End_Date = "2024-12-31T23:59:59Z"
headers = {
"Authorization": f"Bearer {access_token}",
"Content-Type": "application/json",
"Prefer": 'outlook.timezone="Europe/Paris"'
}
params = {
"startDateTime": Filter_Start_Date,
"endDateTime": Filter_End_Date,
"$orderby": "start/dateTime",
"$top": 1000,
"$select": "id,subject,start,end,location,recurrence,seriesMasterId"
}
# Endpoint to fetch all events (including recurrence details)
events_url = f"https://graph.microsoft.com/v1.0/users/{username}/events"
response = requests.get(events_url, headers=headers, params=params)
if response.status_code == 200:
events = response.json()
print("Fetched Events:")
for event in events["value"]:
print(f"Subject: {event['subject']}")
print(f"Start: {event['start']['dateTime']}")
print(f"End: {event['end']['dateTime']}")
print(f"Location: {event['location']['displayName']}")
# Recurrence might not be present for occurrences, so check for it on the seriesMasterId
if "recurrence" in event:
print(f"Recurrence: {event['recurrence']}")
elif "seriesMasterId" in event:
print(f"Event is part of a recurring series (Series ID): {event['seriesMasterId']}")
else:
print("Recurrence: None")
print("--------------------------------------------------")
else:
print(f"Error: {response.status_code}")
print(response.json())
If still the issue persists, check the below:
- Make use of
/calendarViewendpoint instead of/events. Refer this SO Thread by Slipstream. - Make sure to pass different values for Filter_Start_Date and Filter_Start_Date.
- Try to handle pagination if the result contains more than 1000 events.
