Visibility of MS 365 Calendar for other apps

thomash

I am new to GrapheneOS (GOS), and have the problem that I cannot synchronize my employer's "MS 365 calendar" with any other calendar on GOS. I am sure that I am not the only GOS-user with that problem, and wonder how other users are solving this problem?

Technical Details:

Pixel 9 Pro, on Android 16
My employer uses "MS 365"
In order to have an overview of all my appointments, I would like to synchronize the MS 365 calendar with another app. (I have been using "aCalendar+").
After installing the "Outlook" app I have access to my MS 365 calendar.

Problem:

I cannot see any "Exchange" or "MS 365" account in my GOS "Accounts"-List (and as I did on my previous Android mobile phones). Trying to add another Outlook account with my work email brings the message that my email is already used for an "MS 365" account.

How can that problem be solved?

This option can be controlled by your employer, in other words they can disallow it. Are other employees of the company able to synchronize their M365 calendar to other non-Microsoft apps?

fid03 Yes, they can. But they don't have GrapheneOS.

Do they support caldav? If so, use DavX5.

Thats more to do with Office 365, aka CoPilot365 or Microsoft365 ( whatever they call themselves these days).

Afaik, only Outlook can succesfully connect to Exchange 365 online and MS have changes the protocol & language to ' allow" non-standard applications to connect unsecure to OWA / IMAP / Exchange.

I cant recall now the features name but it happened a while ago...a compatibility services.
