No MS Teams add-in in Outlook 365

Hello - I have outlook 365 (latest) and MS Teams (latest) installed on my desktop PC (using desktop client not web) however in Outlook I do NOT see any options to schedule a Teams meeting (only zoom).  I already signed out of teams and restarted outlook but no help.  I also looked in add-ins and do NOT see Teams listed:

I also do not see Teams listed as an add-in under manage...

Why is the add-in not part of Outlook 365?  I did migrate from outlook 2010 when upgrading to Microsoft 365, but Teams should still be a part of the add-ins from what I read.  How can I manually add-in Teams as an option (like zoom) - i do NOT want to uninstall/re-install.  There should be some exe file to add Teams into outlook 365.

Please help!!

Thank you

Hi skeefiez11,

Are you using Teams Free?  The addin only works with office 365 mailboxes that include a teams account. 

If you have a business account with teams license, see this article for troubleshooting steps (at the end of the article) 

https://docs.microsoft.com/microsoftteams/teams...

This is what seems to help most people -
Restart the Teams desktop client.
Sign out and then sign back in to the Teams desktop client.
Restart the Outlook desktop client. (Make sure Outlook isn't running in admin mode.)

Hello Diane - Yes I am using the Teams Free.  So what you are saying is that with Microsoft/Outlook 365, I cannot schedule a Teams meeting??  Not very good when Teams should be a part of MS 365 which I pay for :(

So no other option?

I also see the add-in dll on my PC:

Thx

Additional info - I just tried running teams as Administrator (I signed out of teams 1st and I am the admin), but all I see then is a blank screen where the login screen should be.  Works fine when running as normal and get the login screen.

This is frustrating!!!

>> Microsoft/Outlook 365, I cannot schedule a Teams meeting?
At this time, correct. You need an office 365 business mailbox to link it to outlook.

You should be able to schedule a meeting in teams. If it's not sent from teams, you can get the link then send it in a meeting request.

Hello Diane - Thanks for the link.  However the table does not say anything about no add-in for Outlook 365

Thanks

The addin is linked to the calendar in an office 365 mailbox. Support for Outlook.com mailboxes is rolling out - but you need 2-factor enabled. If you setup teams free using an outlook.com address and have 2FA enabled, you may have the addin now.
https://docs.microsoft.com/microsoftteams/teams...

Try this: After signing into Teams, restart the app. Then restart Outlook. If teams supports your mailbox, that usually brings the button up.

You can schedule a meeting from the team app and share it using Outlook if the addin isn't working.

Hi Diane,

Unfort no it did not add the button.  I also have skype which is supposed to be a part of office 365 but I did not see the meeting add-in either in Outlook.  That should at least be there! see original picture above..  

In any case I looked further in Customize Ribbon and saw under "All Tabs" >> Calendar Tools>> Online Meetings tabs for both Skype and Teams...  I added those to the Home (Mail) tabs:

and they appeared on the Home ribbon as you can see, HOWEVER.....

As circled, the button for skype which only says "Join Skype meeting" is highlighted as if it is available, but clicking on it does nothing...  Also "Join Teams Meeting" is not highlighted like it was in the 1st picture so it is not even clickable :(

So something is still not right here even though I did see the following directories in appdata>> local >> Microsoft:

In the meeting-addin-install-logs I see:

2020-06-12-09:53:44.669 AM System.ArgumentException: Cannot delete a subkey tree because the subkey does not exist.

2020-06-12-09:53:47.340 AM Version 1.0.20091.2 of the meeting add-in is now installed

So I have no idea why this is not working (and neither is the Skype meeting add-in).

As a reminder for add-ins I see only this (only Zoom, not skype nor Teams)

Did a search in C: for any .dll named *outlook*.dll but only outlook plugin was for zoom and nothing for skype or teams :(  Please help?

Thanks

The forum removed the address, but if it is not an outlook.com address (including hotmail, live. msn, or a custom domain hosted by outlook.com) or an office 365 business address, the teams addin won't work. It uses the calendar in your outlook.com/office 365 mailbox to create the meeting. You can schedule meetings in Teams and send via outlook.
