Hi

Normally, users without a license can also create meetings with Teams.

Can you provide specific steps for creating a meeting?

Please try following the documentation steps to invite only users within your organization to create meetings to check for discrepancies.

Also, please run the following test to troubleshoot the problematic account: Run Tests: Teams Calendar App.

Hi @Kelvin Cheng

For our better research, please provide more information about this case:

What's the version of your Outlook? (File > Office Account > About Outlook). Please make sure you have upgraded your Outlook to the latest version.

Do other users who received the meeting invitation have the same problem? Or do you change a device to check for discrepancies.

This can be caused by some settings in Outlook that affect how HTML messages are displayed. Here are some possible solutions you can try:

Please confirm the format is set as HTML via File>Options>Mail>Compose messages.

Please confirm the "Read all standard mail in plain text" option is unselected via File>Options>Trust Center>Trust Center Settings…>Email Security>Read as Plain Text.

Hope this helps!

Hi @Kelvin Cheng

Are the meeting details in the Teams calendar showing normal?

You can also cancel below settings in Outlook options and test if working or not. As iCalendar is not native to Microsoft standards and may have some compatibility issues.

We reminded to sender to unselect "When sending meeting requests outside of your organization, use the iCalendar format" before send invitation. But problem still appear.

Hi

In order to better study this issue, can you provide more information:

Is it a specific meeting or all meeting invitations showing codes?

In order to troubleshoot whether it is your Outlook client, it is recommended that you create a meeting by yourself and check whether the invitations received by attendees are normal?

Try checking if the meeting invitation appears properly in safe mode. （Windows + R> type "outlook.exe /safe">enter).

All problem meeting invitation mail from Japan to Hong Kong.

User haven't Temas license, so could not create meeting via Teams.

We tested this method but problem still appear.
