I recently had a user that was unable to Lync 2010 Online Meetings from Outlook 2010. He didn't even have the button to create one. Otherwise his Outlook worked fine, no problems sending or receiving email, or scheduling meetings.
Fixing the Issue
My first thought was the Conferencing Addin was disabled. When I looked into his settings it was, but the Conversation History Addin was active. For some reason the Online Meeting Addin would not enable though. I ran a repair on the Lync client, no change. I had my Service Desk uninstall and reinstall the client thinking something was still corrupted with the install. No change.
Then one of the guys fixed it. Somehow the user had corrupted his Navigation Pane view. To fix this, click Start and in the search/run box type outlook.exe /resetnavpane
After this was done, we could enable the Online Meeting addin and schedule meetings.
Hope this helps!

Fun Fact:
There is no definitive history about how the word “barbecue” originated – or why it’s sometimes used as a noun, verb, or adjective. Some say the Spaniards get the credit for the word, derived from their “barbacoa” which is an American-Indian word for the framework of green wood on which foods were placed for cooking over hot coals. Others think the French were responsible, offering the explanation that when the Caribbean pirates arrived on our Southern shores, they cooked animals on a spit-like devise that ran from “whiskers to tail” or “de barbe a` queue.”
