Question

Outlook says I need to log in to Teams to book a Teams meeting but I am logged in

KB 10

Recently installed Office 365 suite and Teams on laptop (running Win10 x64) and successfully installed Outlook and connected to email service. Initially had trouble getting 'create Teams meeting' button to even appear in calendar appointment creation window despite Add-in being present and active in Outlook. Re-installed everything and resolved that issue. Now, however, when I press the Teams Meeting button in the calendar creation window the pop-up states: "To schedule a Teams meeting make sure you're signed in to Teams". Teams (new) is active and running on this laptop and I am signed in. So where is the problem?

I have un-installed and re-installed Teams and Office 365 multiple times and wiped the credentials records and and cache to no effect. Thank you.

Hi @KB

Welcome to our forum!

What is the version of your Outlook? It is recommended that you please check the Outlook client version (File>Office Account>Product Information) and try to upgrade to the latest version to see if the problem persists.

In addition, it is suggested that please open the Outlook in safe mode (Hold the Ctrl key while starting Outlook) to see if the issue persists, if not, considering the issue may related to the Teams Meeting add-in for outlook, please refer to the article to troubleshoot: Resolve issues with Teams Meeting add-in for Outlook - Microsoft Teams | Microsoft Learn User's image Meanwhile, i found a similar thread approved by most people, please feel free to refer to it. Hope it helps!

Thanks for the reply.

Version is Microsoft® Outlook® for Microsoft 365 MSO (Version 2406 Build 16.0.17726.20078) 64-bit.

Interestingly, when I run Outlook in safe mode the Teams Meeting button disappears. Then when I run it normally it re-appears. Not helpful, of course. Just interesting.

I've run the Add-in diagnostic numerous times throughout the many instances where I've un-installed and re-installed O365, Outlook and Teams. I get different results each time. This latest result states Microsoft Teams is not installed, which is, of course, preposterous because I'm looking right at the open, working application. I have seen this result before, after which I un-installed and re-installed everything. More than once. How can Teams be installed and connected to my account and yet not recognized by Outlook? That being said, it doesn't currently appear to have synced my calendar even though it is signed in to my account/profile.

Hi @KB

Thanks for your response.

To further confirm if the issue is more related to Outlook desktop client, if possible, please log in to your web mail and do the same operation to check if the issue persists.

And what is your account? Outlook.com or something else?

If you are using an Outlook.com, you may refer to the article to handle the issue.

If not, you may try the following steps:

Restart Teams Completely: Right-click the Teams icon in the taskbar, click qiut Teams and then relaunch Teams.

Sign Out and Sign Back in: Sign out of Teams from your account menu and then sign back in with your credentials.

Fix the issue of add-in in Outlook manually: please refer to the article for details.

Uninstall the Microsoft Teams Meeting Add-in:

Windows Start>Settings>Apps>Installed Apps, then search for the Teams Meeting Add-in>Click the three dots and select Uninstall>Close Outlook>Quit Teams from the taskbar>Restart New Teams and Outlook.

If all above do not work, considering data file corruption, it is proposed that you create a new profile, re-add your account to the new profile and check if the same issue still occurs.

Hope it helps!
