Appointment Invitation Remain Unread in Outlook Inbox

Hi @Blagojevic Jovana ,

Welcome to the Microsoft Q&A platform!

Based on your description, you are experiencing a known issue with Outlook. Other users have also reported this behavior, where the invitation remains in the Inbox after accepting it from the calendar.

Here are some potential workarounds you can try:

1. Make sure your Outlook is up to date. Sometimes new versions fix bugs.
2. You can try repairing your Outlook installation. Go to Control Panel > Programs and Features, select Microsoft Office, and then select Change > Repair.
3. Verify the settings in Outlook. Go to File > Options > Mail, and then check the settings under Send Mail. Make sure the option to Delete meeting requests and notifications from the Inbox after responding is enabled.
4. As a temporary workaround, you can accept the meeting invitation using Outlook Web App. This may not exhibit the same issue.

If these steps do not resolve the issue, creating a new Outlook profile may help. This can sometimes clear up unexpected behavior.

Please feel free to contact me for any updates. And if this helps, don't forget to mark it as an answer.

Best,

Jake Zhang
