A collaborative workspace app in Microsoft 365 designed to help teams co-create, stay organized, and work together in real time across apps and devices.
Thank you for providing the detailed information and the troubleshooting steps you've already performed.
Before investigating further, I'd like to gather a few additional details to help narrow down the cause:
- Is the affected Gmail user already added as a guest user in your Microsoft 365 tenant (Microsoft Entra ID), or are they accessing the workspace only through the invitation email?
- Is this issue affecting all external Gmail users, or only specific guest users?
- Has your IT administrator confirmed that external sharing and guest access are enabled for Loop, SharePoint, and Microsoft 365 in your tenant?
- Are the affected users able to access other shared Microsoft 365 resources (such as SharePoint sites or Teams content) as guests?
- If possible, could you provide a screenshot of the loading screen that appears after the user selects Join Workspace?
Based on your description, one area worth checking with your IT administrator is whether your tenant meets the requirements for sharing Loop workspaces with external users. Microsoft notes that workspace sharing with external users requires the appropriate guest access and external sharing configuration to be enabled in the tenant.

In particular, the article explains the requirements for guest/external sharing, including guest accounts, tenant-level sharing settings, and other policies that may affect access to entire Loop workspaces.
I apologize for asking so many questions, but this information will help me better understand whether the issue is related to the guest account itself, tenant configuration, or the specific Loop workspace configuration.
Thank you again for your time and understanding. I really appreciate your patience, and I’m here to help. Looking forward to your response.
