Unable to share externally on Shared Channels
The B2B settings should have propagated by now, but still no luck. Here are the updated settings as well as others I had now shown before:
Cross-tenant access settings:
External collaboration settings:
Global Teams policy
Trying to share from SharePoint on a shared channel's site is unchanged. I still get the following message for external email addresses:
Your organization's policies don't allow you to share with these users. Go to External Sharing in the Office 365 admin center to enable it.
If I click on "Share with people" on a shared channel and enter an external email address, I get "We didn't find any matches". The same occurs if I enter the email address of an existing guest account.
However, I can add an external user to the Team.
When I sign into Teams as the external user, I can see the team and the General channel, but not the Shared channel, which is shared with the team.
Are there any other settings I could be missing?
Thanks,
Ryan
1. You have not added the external people to your shared channel, and
2. You are trying to share files / folders out of SharePoint with external users?
If so, because it's a shared channel you won't be able to share with external users unless BOTH you AND the external user's tenant have configured the Azure AD B2B direct connect settings. If the external user's tenant hasn't been configured, then I'd expect what you're seeing, i.e. not finding the external users when trying to add them to the channel.
My issue is slightly different, in that I can add them to the channel, they can access it and join in conversations, but they get a "That didn't work. External Sharing is disabled" error when trying to access / upload files.
- Microsoft support confirmed that external users and guests are not yet supported in shared channels unless they have M365 accounts with B2B direct connect configured. That is a huge loss of functionality compared to private and standard channels. We collaborate with tons of external users that have no M365 subscription. We migrated everything to shared channels to help consolidate and organize our teams. But in the process lost the ability to search and share (search currently does not work in shared channels either). It's a huge deal breaker. Microsoft Support has been utterly useless in the process, so we are currently migrating to Google Workspaces. It took Microsoft Support two months to even confirm that sharing with external users is not possible on shared channels. They have no ETA on a fix.
- Thanks for your response. "Microsoft support confirmed that external users and guests are not yet supported in shared channels unless they have M365 accounts with B2B direct connect configured." seem to indicate that as long as you have an M365 account and B2B direct connect is configured, external sharing is possible with files/folders stored in a Shared Channel linked SharePoint Online site. We have both turned on, and I am assuming the other party has to turn it on too. It is a major limitation.
MichaelDelpach do you know if this has been updated/corrected? "Microsoft support confirmed that external users and guests are not yet supported in shared channels unless they have M365 accounts with B2B direct connect configured." When I try to add an external user that is not affiliated with Microsoft I get this:
and I know the e-mail address is correct.
