i am using To do and want to assign task to my subordinate but the link i share is not working

Answer 1

It seems you're experiencing issues with sharing links in the Outlook To Do app, specifically regarding task assignments to your colleague. Here are some steps you can take to troubleshoot the issue:

1. Confirm Permissions: Ensure that the colleague you are trying to share the task with has the necessary permissions to access the shared link. If they are not part of the same organization or if their account is not set up correctly, they may not be able to join.
2. Check Link Validity: Make sure that the link you are sharing is valid and not a fictitious domain. If the link uses a domain that Outlook cannot recognize, it may prevent access.
3. Sign-In Issues: Verify that both you and your colleague are signed into the correct Microsoft 365 account associated with the link. If your colleague is not signed in with the appropriate account, they may face issues accessing the shared content.
4. Browser and App Compatibility: Since you mentioned trying different browsers, ensure that the To Do app is updated to the latest version. Sometimes, compatibility issues can arise with older versions of the app.
5. Outlook Tasks Link: If the "Sync to Outlook" button or the "Tasks" link is missing, you may need to manually restore the link to your personal site as described in the troubleshooting documentation.

If these steps do not resolve the issue, consider reaching out to your IT department or Microsoft support for further assistance.
