We couldn’t schedule the meeting – Teams error in Outlook
To fix this issue, follow these suggestions-
1] Paid subscription required
You cannot use this functionality in the Outlook web or client without having a paid subscription. You can purchase any subscription among Microsoft 365 Business Basic, Business Standard, and Microsoft 365 E3.
2] Use the same account
It is mandatory to use the same account that you used to purchase the subscription. If you use two different accounts in the Outlook app, it won’t detect the subscription due to obvious reasons. Therefore, it is required to use the same account across all apps to get this feature running.
3] Remove other accounts
Many people use multiple accounts in the Outlook app. If you are using Gmail, Outlook, Yahoo Mail, etc., together, it is better to remove other accounts and check if the problem remains or not. Although multiple accounts should not create issues on paper, it does when the Outlook app cannot fetch everything correctly. At first, open the Outlook app, and click the File option in the top menu bar. Click on the Account Settings button and choose the Account Settings option from the list.
It opens a list of accounts you have added to the Outlook app. Choose an account and click the Remove button.
Next, restart the Outlook app and check if you can schedule a meeting or not.
4] Log out and log in again
If you recently purchased the Microsoft 365 subscription, Outlook might not be able to detect your subscription. At such a moment, it is better to log out of your account and log in again. Although there is no direct option like the Outlook web version, you can use two different methods. One, you can change the profile and select it again. Two, you can remove your account and add it again. To get started, open the Outlook app and click the File menu to choose the Account Settings option.
Following that, select the Change Profile option and click the OK button to restart Outlook and change profile.
Secondly, you can click the Account Settings and choose Account Settings option from the list. Now, select your account, and click the Remove button.
5] Disable/Enable Microsoft Teams Meeting add-in
As this particular error message is based on the Microsoft Teams Meeting add-in, you can try disabling and enabling the corresponding add-in. For that, open the Outlook app and click the File > Options > Add-ins. If you can see the Microsoft Teams Meeting Add-in for Microsoft Office under the Active Application Add-ins heading, choose COM-Add-ins from the Manage drop-down list, and click the Go button.
Next, remove the tick from the respective checkbox, and click the OK button. Then, repeat the same steps to re-enable it. After that, try scheduling a meeting. Hope one of these solutions work for you.
