After installing MS teams on a machine that has Outlook 2013. You might not be able to send Skype meetings invitations through outlook. So when you try to schedule a meeting, you’d see something like this:

There’s no option to send a Skype meeting. It might be OK for users who use O365 only, but for companies who are still transitioning from SharePoint on prem to SharePoint online, that might be an issue.

To solve this, go File and click Options, then click Add-Ins. You’ll notice that Skype Meeting Add-In for Microsoft Office 2013 is deactivated. At the bottom of this page where it says Manage COM Add-Ins, click Go:

Check the Skype Meeting checkbox, and hit OK. Now you’re good to go!

As can be noticed, both Skype for business meetings and Teams meetings are added to Office as Add-Ins, which can be activate/deactivated when needed.
