Unable to edit a shared (Office365) family calendar.

This is a family Office 365 account. My wife is the admin for the account. She has shared a calendar with me, with Edit functionality.

However I can only view the calendar but not edit it/add events etc.

Have tried Outlook on web, and outlook app (Windows 11).

Have tried New outlook & Classic outlook.

Still not working.

Any suggestions please ?

    For a personal/family Outlook.com calendar, the most reliable fix is to remove the broken share and create it again from Outlook on the web.

    1. Sign in to the calendar owner’s Outlook on the web account.
    2. Go to Calendar.
    3. Right-click the shared calendar under Calendars and select Sharing and permissions.
    4. Remove the existing permission entry for the other family member.
    5. On the recipient side, remove that shared calendar from the calendar list as well.
    6. Share the calendar again from the owner account, and assign Can edit.
    7. Accept the new invitation in Outlook on the web. If the invitation in another Outlook app does not show Accept, use Outlook on the web to accept it.

    Important checks:

    • For Outlook on the web, Can edit is the permission that allows editing. Delegate also allows editing and can act on behalf of the owner for meeting requests.
    • If the shared calendar invitation is not accepted properly, the calendar may appear but remain view-only.
    • Some Outlook apps may not send or process the sharing invitation correctly. In that case, re-share from Outlook on the web and accept in Outlook on the web.
    • If the shared calendar is not yet upgraded to the newer sharing platform, remove it, restart Outlook, then re-add it using Add Calendar > Open Shared Calendar.... Do not use Add from address list, because that adds it as a MAPI shared calendar.
    • After re-adding, the calendar can appear empty at first while it syncs. Initial sync can take a few minutes, and large calendars can take a few hours.

    If the calendar still opens as view-only after re-sharing, create a new blank calendar in Outlook on the web and share that new calendar with Can edit instead of continuing with the existing one.

    Hi Christopher Jaques

    One thing to confirm: are both accounts using personal Outlook.com/Microsoft 365 Family accounts, or is either account connected to a work or school Microsoft 365 tenant? Also, when your wife checks Sharing and permissions, does it still explicitly show your account as Can edit rather than Can view all details? A screenshot of the permission setting (with email addresses obscured) may help identify whether this is a permissions issue or a synchronization problem.
