Microsoft Tools for Small and Medium Businesses AMA

Hey Michelle, can you elaborate what do you mean "clients who give me access to their 365 environments." Are you a B2B guest in their tenant or a member in their tenant. If you are a guest, you will see (Guest) next to your name.

Also would Microsoft Bookings for you?

Hi Michelle (normaluser)! This may be a solution. Let me know if it works or not.

Sharing Free/Busy Information in Outlook 365 (Web Version)

1. Open Outlook Web Access (OWA):

   • Go to https://outlook.office.com or access your Outlook through your Office 365 account.

2. Go to the Calendar:

   • On the bottom-left corner, select the calendar icon.

3. Select the Calendar You Want to Share:

   • In the left pane, find the calendar you want to share (your personal calendar). It should appear under the "My Calendars" section.
   • Hover over it and click the three dots (ellipsis) next to the calendar name.

4. Choose Sharing and Permissions:

   • From the dropdown menu, click on Sharing and permissions.

5. Add the Client's Email Address:

   • In the window that appears, enter your client’s email address (even if they are on a different domain).

6. Select Permission Level:

   • When adding the email address, you will be given different sharing options. Choose Can view when I’m busy. This will allow the recipient (your client) to see your Free/Busy status without viewing any specific details of your appointments.

7. Send the Invitation:

   • After selecting the appropriate permissions, click Share. This will send an email to your client inviting them to view your Free/Busy information.

Sharing Free/Busy Information in Outlook Desktop App (Windows/Mac)

1. Open Outlook Desktop:

   • Launch your Outlook desktop app.

2. Go to the Calendar:

   • In the bottom-left corner, click the calendar icon.

3. Select Your Calendar:

   • In the left pane under My Calendars, find and select your primary calendar.

4. Click on Share Calendar:

   • Go to the top of the window and click the Share Calendar button. A new window will open.

5. Enter Client’s Email:

   • Enter the email address of the person (client) you want to share your calendar with.

6. Set Free/Busy Permissions:

   • In the permissions dropdown, select Can view Free/Busy time. This will ensure that the recipient can only see your availability (free/busy) and not any event details.

7. Send the Invitation:

   • Click Send to share the calendar.

Notes:

• If you are working across different domains, ensure that your organization allows sharing calendars with external users. In some cases, the Office 365 administrator might need to enable this feature.
• This method only shares your Free/Busy information, which is ideal for your scenario since it keeps the details of your meetings private but still lets your client know when you’re available for booking meetings.

If your client accepts the invitation, they will be able to see your Free/Busy availability on their calendar, even if they are on a different domain.
