If it isn't possible to generate a new invite, the person who invited you can remove the first invite/share and then create a new one.

    Hello, thank you for reaching out to Microsoft Q&A.

    You will need to accept the invitation link within 48 hours from the time it is sent to you; otherwise, the link will expire.

    Ask the Organizer to send the invite through SMS or through a social media app. That is,

    • Go to https://account.microsoft.com/services
    • Sign in with the Organizer Microsoft account that is associated with an Office 365 Family license.
    • Click Start Sharing > Copy Link.
    • Paste the link on the SMS or social media app and click send.
    • You accept the invite.

    Let me know if you still need more help.

    The behavior matches a known issue where accepting certain invitations (for example, shared calendars or sharing/guest invitations) shows “Something went wrong,” and the sender cannot resend because the system still sees an existing invitation.

    Use the following pattern to resolve it, depending on what type of invitation it is:

    1. Ask the inviter to remove your access/permissions completely
      • For a shared calendar: the owner should remove your sharing permissions from their calendar.
      • For a SharePoint/guest-type invite: the admin may need to remove your guest account from the directory (soft-delete) and then reinvite.
    2. Have the inviter send a fresh invitation
      • After permissions or the guest account are removed, the inviter should send a new invitation.
    3. Accept the new invitation using a supported client
      • For Outlook.com calendar shared to a Microsoft 365 business account: accept the new invite from Outlook on the web, iOS, or Android instead of the desktop Outlook client. If the original invite was already accepted or clicked in Outlook 2016, it cannot be re-used; only the new invite will work.
      • If an HTTP 500 or similar error appears when accepting a shared calendar, select Accept again; Outlook should then complete the acceptance.
    4. If the issue is with a SharePoint Online/guest invitation
      • A Microsoft 365 admin can:
        1. Use Microsoft Graph PowerShell to locate and remove the guest user account.
        2. Clear the browser cache (including cookies and website data) on the guest’s browser.
        3. Reinvite the guest and have them open the link in an InPrivate/Incognito window to avoid cached credentials.

    If the inviter still sees that the invitation already exists after removing permissions or the guest account, they should wait a short period and then try sending the invitation again.
