Guest Permissions Overview
What Are Guest Permissions
Guest permissions in Microsoft 365 Teams help you decide what outside users can do. When you invite a guest, they get an email to join. After they accept, they can talk in chats, share files, and join meetings. You will see “(Guest)” next to their name, so you know they are not part of your company.
Guests cannot do everything team members can do. The table below shows what guests and members can do:
You can change guest permissions to match what you want. By default, guests can send messages, share files, and use chat. They cannot make new channels, add apps, or delete tabs.
Why Control Guest Access
It is important to control guest access to keep your team safe. If you do not control it, there are some risks:
Someone might share data by mistake with open links.
Guests might still get in if you forget to remove them after a project.
You might break rules like GDPR or HIPAA.
It can be hard to watch and check guest accounts.
Tip: Check guest permissions often and remove guests who do not need access anymore. Set end dates for sharing links and mark important data to stop leaks.
Microsoft 365 Guestmanagement lets you make clear rules for guests. You can keep your data safe and follow the law by managing guest access well.
Enable Guest Access
You need to do some steps before letting guests join Microsoft 365 Teams. These steps help keep your information safe. They also make sure only the right people can get in.
Organization Settings
You must be a global administrator to start. This role lets you change settings for everyone in your company. Check these main areas before you turn on guest access:
To change these settings, go to the Microsoft 365 admin center. Click Settings, then Org settings, and pick Microsoft 365 Groups. Here, you can turn on guest access for Teams and SharePoint.
Note: Microsoft 365 Guestmanagement helps you pick who can join your Teams and what they are allowed to do.
Team Settings
After you turn on guest access for your company, team owners can add guests to their teams. Here is what you need to do:
Make sure guest access is turned on in Azure Active Directory, Microsoft 365 Groups, and SharePoint Online.
If you are a global admin, open the Teams admin center.
Go to Users and then Guest access.
Choose what guests can do for calls, meetings, and messages.
Save your changes.
Team owners can now invite guests by sending an email.
Guests get an invite and can join using the Teams app or website.
You can set what guests can do for each team. This helps you control if guests can chat, join meetings, or share files.
Customize Guest Permissions
Teams Settings
You can change what guests do in each team. Team owners can set these permissions. Here is how you do it:
Find the team name in Microsoft Teams.
Click the three dots next to the team name.
Pick Manage team.
Go to the Settings tab.
Click Guest permissions.
You will see boxes for different actions. You can let guests make, change, or delete channels. You can also let guests delete messages or edit posts. If you want to stop guests from doing something, uncheck the box for that action.
Tip: Check these settings for every team. Some teams need more limits than others. Change them if the team shares important information.
File permissions for guests are set in SharePoint. Only an admin can change these settings. If you want to stop guests from sharing files, ask your admin to change SharePoint sharing.
Guest Capabilities
Guests in Microsoft Teams cannot do everything members can. They still work with your team. Here is what guests can and cannot do:
You cannot give different permissions to each guest. Microsoft 365 Teams uses the same guest settings for everyone. If you want to change what guests do, update the guest access settings for all guests in the Teams admin center. Here, you can let guests chat, call, or join meetings.
Note: Microsoft 365 Guestmanagement does not let you set special rules for one guest. All guests follow the rules your admin sets.
When you share files with guests, remember these tips:
Turn on guest or anonymous access only if your company says it is okay.
Set up relationships in Microsoft Entra ID for safe teamwork.
Use shared channels to work with partner companies. This means you do not need lots of guest accounts.
Use entitlement management in Microsoft Entra ID for vendors.
Stop mistakes by checking sharing settings often.
Match sharing features with your company’s rules.
Guests only see the teams and channels you invite them to. They cannot see other parts of your network. This keeps your data safe and helps you follow security rules. Microsoft 365 Guestmanagement lets you work together easily and keep your data protected.
Tip: Check guest permissions often. Remove guests who do not need access anymore. This keeps your Teams safe and current.
Manage Guest Access
Monitor Guests
You should watch who your guests are and what they do in Microsoft 365 Teams. Checking guest activity helps you find problems and keep your data safe. There are different tools to help you:
Microsoft Teams admin center has usage reports. You can see which guests use Teams, what messages they send, and when they join meetings.
Microsoft 365 usage analytics shows how guests use Teams. You can check when they log in and what devices they use.
Teams audit logs let you look at guest actions. You can see if they make teams, change channels, or post in chats. These logs help you follow rules.
Syskit Point puts all guest users in one list. You can control access, remove sharing links, and get alerts when new guests join. Syskit Point also helps with guest recertification.
Other tools like ShareGate have dashboards for watching and enforcing rules.
Tip: Check guest activity often. Set alerts for new guests and automate reports so you always know what is happening.
Microsoft 365 Guestmanagement helps you see who has access and what they do. These tools help you keep your Teams safe.
Remove or Review Guests
You need to check guest access often to make sure only the right people are in your Teams. Microsoft 365 Guestmanagement gives you different ways to do this:
Use Entra access reviews in the Azure portal. Make a review for Teams and Groups with guests. Pick reviewers, set rules for inactivity, and choose how often reviews happen. Reviewers get emails and can approve or deny guest access.
Run reports in the Teams admin center. Filter by guest role to see all guests in each team. Remove guests who do not need access anymore.
Use PowerShell scripts to list and remove guest users. This works well for big groups.
Try tools like Syskit Point or sapio365 for easy bulk removal. These tools let you filter guests, see memberships, and remove users quickly.
You can remove guests by hand in the Microsoft 365 portal, but it takes longer for big groups.
Note: Automate access reviews to save time and avoid mistakes. Set reviews every month or every few months for best results.
Checking and removing guests often helps keep your Teams safe and follow rules. Microsoft 365 Guestmanagement gives you the tools to manage guests well.
Microsoft 365 Guestmanagement Best Practices
Security Tips
You can keep your group safe by using good security steps for guest access. Turn on multi-factor authentication (MFA) for everyone, even guests. MFA stops almost all account hacks. Turn off old sign-in methods because they can skip MFA and make your data unsafe. Use Conditional Access rules to make sure guests use MFA and to control how they log in.
Do regular access checks with Microsoft Entra ID. These checks help you find and remove guests who do not need access. You can also use access packages to let guests in for a short time with approval steps. Set session timeouts so guests must log in again if they are idle. This helps if someone leaves a session open.
Tip: Use Microsoft Purview Data Loss Prevention (DLP) to stop guests from sharing private stuff by accident.
Limit guest access from devices that do not follow your security rules. Block devices that are not safe. Change guest permissions in the Teams Admin Center to control what guests can do in meetings, calls, and chats. Always keep a list of trusted domains and block the ones you do not trust.
Compliance
You have to follow laws and company rules when you manage guests. Check guest access at least every three months to stay safe and follow the rules. Make rules that tell team owners to check guest members often. Use sensitivity labels for teams with guests to protect important information.
Microsoft 365 Guestmanagement helps you set up these controls. You can use private or shared channels to limit what guests see. Always teach your users about safe sharing and add security checks to your company rules.
