You cannot join Lync Online meetings in Office 365 Dedicated
When you try to join a Microsoft Lync online meeting on a computer that has Internet Explorer 9 installed, the Lync browser page does not fully load, and you cannot join the meeting.
This issue occurs because of a problem with the MeetingJoinHelper class add-in in Internet Explorer 9. Microsoft is currently investigating the issue.
To resolve this issue, reset the MeetingJoinHelper class add-in. To do this, follow these steps:
- Open Internet Explorer.
- In the upper-right corner of the browser window, click the gear icon to access the Tools menu, and then click Internet options.
- In the Internet Options window, click Programs, and then click Manage add-ons.
- In the Manage add-ons window, click the Currently loaded add-ons drop-down menu, and then select All add-ons.
- Locate the add-in that is called MeetingJoinHelper Class, and then verify that its status is set to Enabled.
- Right-click the MeetingJoinHelper Class add-in, and then select More information.
- In the More Information window, click Remove all sites, and then click Allow on all sites.
- Click Close to close the More Information window.
- Click Close to close the Manage add-ons window.
- Click Okay to close the Internet Options window.
To try a short-term (that is, not permanent) resolution, follow these steps:
- Join the meeting.
- After the Internet Explorer browser page opens, click Refresh.
