It sounds like the issue with two users being shown as external in Microsoft Teams may be related to the settings for external access and guest access within your organization. Here are some steps you can take to address this:
- Check External Access Settings: Ensure that the external access settings in the Teams admin center allow communication with users from other organizations. You can either allow all external domains or specify certain domains that are permitted.
- To check this, go to Users > External access in the Teams admin center.
- Check Guest Access Settings: If the users are meant to be guests, ensure that guest access is enabled. This allows users from outside your organization to participate in Teams meetings and chats.
- You can check guest access settings by going to the Teams admin center and looking under Org-wide settings > Guest access.
- Microsoft 365 Groups Settings: Since Teams uses Microsoft 365 Groups for team membership, make sure that the settings for adding guests to groups are enabled. This can be done in the Microsoft 365 admin center under Settings > Org settings > Microsoft 365 Groups.
- Invite Users Again: If the two users are still showing as external, consider removing them and re-inviting them as guests to the Teams environment. This can sometimes resolve issues related to their status.
By ensuring the correct settings are in place, you should be able to facilitate better communication and video calls within your team.
