Microsoft 365 Certified: Teams Administrator Associate MS-700 Book

To add a disclaimer to all Teams meeting invites, you can use the Exchange admin center to create a mail flow rule that applies the disclaimer to meeting requests. Here are the steps to follow:

• Sign in to the Exchange admin center with your Microsoft 365 username and password1.
• In the left navigation, go to Mail flow > Rules.
• Click Add (+) and then select Create a new rule.
• In the New rule pane, enter a name for the rule, such as “Meeting disclaimer”.
• Under Apply this rule if, select A message header includes any of these words.
• In the Specify header name box, enter X-MS-Exchange-Calendar-Meeting-Request. This is a special header that identifies meeting requests2.
• In the Specify words or phrases box, enter True. This means that the rule will apply to any message that has the header set to True.
• Click Add and then OK.
• Under Do the following, select Append the disclaimer.
• In the Specify disclaimer text box, enter the disclaimer text that you want to add to the meeting invites, such as:

Disclaimer: This meeting may be recorded for quality and training purposes.

• Click Enter text and then OK.
• Under Choose a mode for this rule, select Enforce.
• Click Save.

Now, when you or anyone in your organization schedules a Teams meeting, the disclaimer will be added to the meeting invites automatically.

To ensure that only users from litwareinc.com can be added to Teams as guest users, you need to configure the guest access settings in Azure Active Directory (AAD). Here are the steps to follow:

• Sign in to the Azure portal with your admin credentials.
• Go to Azure Active Directory > External identities > External collaboration settings.
• Under Collaboration restrictions, select Allow invitations only to the specified domains (most restrictive).
• In the Allow invitations to these domains box, enter litwareinc.com. You can also add more domains if you want, separated by commas.
• Click Save to apply the settings.

That’s it. You have successfully restricted the guest access in Teams to a specific domain. This means that only users with email addresses from litwareinc.com can be invited as guests to your teams. You can also prevent guests from being added to a specific team by using sensitivity labels1 or PowerShell2.
