Hi, 

I have been using CalenGoo for a long time and I really love the app. It is by far my favourite calendar app. 

I recently received a notification from Microsoft 365 that an application in my tenant is using Exchange Web Services (EWS), which will be retired by Microsoft in October 2026. 

I noticed in the CalenGoo forum that it is possible to use Microsoft Graph API instead of EWS. In my CalenGoo settings, my account type is currently set to Exchange. 

Could you please let me know how I can switch my existing account from Exchange/EWS to Microsoft Graph API? I have not been able to find where this setting is changed. 

Thank you very much for your help, and thank you for developing such a great app! 

Best regards,

Marianne

Hi Marianne,

thank you very much! I am glad that you love it! 😊

Syncing via Graph API is a new account type: Just open "Settings > Accounts" in CalenGoo and uncheck or remove your Exchange/EWS account. Then tap "Add account > Outlook/Office 365 (Graph API)" to add it again.

Please try this and don't hesitate to contact me again if you have any problems or questions!

Kind regards

Dominique
