To get this functionality back the user will need to switch back to their home tenant/account, restart Outlook, and then the button will be back. However in the scenario where a user is in an external network, shuts down their computer at the end of the day, and comes back in the next day: Teams will join back into the last tenant/account is was connected to, and therefore Outlook won’t show the Teams Meeting add-in. I suspect for the average user while Teams is somewhat still new in many organisations this is not an issue as users will reside in their home tenant/account. If Teams sign signed into an external tenant/account when Outlook opens: the Teams Meeting option is not there.If Teams is signed in to your home tenant/account when Outlook opens: the Teams Meeting option is there.Long story short, by process of elimination I found that: Then, Office on my Surface went through some updates and Outlook restarted, and presto: the Teams button was missing too! I started checking for missing add-in DLLs, registry keys, scouring the web for blog posts, etc. I compared my desktop against my Surface Pro and found that they had slight variations in build numbers for both Outlook and Teams so I thought that perhaps a bug had been introduced in a newer build on my desktop. I had a short moment of panic when I could no longer see the ability to schedule a Teams meeting, as it had disappeared from Outlook: What you see in the calendar view in Outlook is options for both Skype Meeting and Teams meeting, as well as in the New menu dropdown when in the inbox view:


A few months ago, the ability to schedule a meeting in Teams directly was made available in Outlook, and it’s been a wonderful thing.
