Dear Andrew J SMITH#56,
Good day! Thank you for posting to Microsoft Community.
I'm sorry to hear that you are experiencing difficulties with sharing a whiteboard in Microsoft 365 business standard with external guest users. However, I can confirm that the ability to share and collaborate using Whiteboard during a Teams meeting with external guest users is available in Microsoft 365 Business Standard. Therefore, this feature will allow users to share whiteboards with external guests of your tenant via a personal share link (PSL). This feature will respect any OneDrive/SharePoint sharing settings your tenant has enabled. Additionally, if your tenant has Business to Business Invitation Manager (B2B IM) enabled, this feature will allow you to send a whiteboard via PSL to external users and B2B IM will create a guest user account for them so they can access the file. However, there are a few requirements that must be met for external sharing to be possible:
- Business-to-business only: the user you are sharing with must have an AAD account.
- Guest only: the user you are sharing with must have a guest account in your tenant.
- Your company must allow sharing files with external users.
For homework, you can set up guest users to access to their whiteboard at any time via a USRL added to their personal OneDrive folder. For additional information, you can refer to External Sharing - Microsoft Support
However, I do understand your concern about this feature that how it helps you to improve your work efficiency but currently the feature you are inquiring like share whiteboard during team meeting and outside of the hour of teams meeting for guest/external access doesn't seem feasible at the moment, so I greatly appreciate your suggestion and apologize for the inconvenience this may cause. At this point, it is suggested to submit your valuable feedback directly to Microsoft product development team by either go to Help from your dedicated App > submit Feedback or by posting on Ideas · Community (microsoft.com) . This is require because as we are from community team, we can only assist you to troubleshoot the query/share work around (if we have for any by design query) and providing you required information for feature’s availability status.
I also understand your frustration regarding the differences in functionality between Microsoft 365 Education and Microsoft 365 Business Standard. However, it is important to note that these are two separate products with different features, pricing structures and design purpose. As a result, there are some more efficient and free services in one subscription plan, while they are limited on the other subscription as both are used for different purposes and are used by different users. Therefore, I will surely raise your concern to our dedicated product development team and also submit your valuable suggestion via the above feedback link. Hopefully your suggestion will help many other users in the future.
