After sharing a Sub-Site with an external user (requiring Microsoft live login) the external user cannot access a document library within the site.
I'm getting the "Sorry, you don't have access to this page" response.
Initially, when I tested sharing on a different site collection, the external user could access the library fine.
Differences between test library and current library:
- Current library has Approve/Reject and Versioning
- Current library has a Column (defined at the top site) that is a lookup to a list (also on the top site).
- Library page has a Query URL String web part which provides a filter targetting the lookup column.
- Library has 2010 and 2013 workflows.
- Librarys new and modify form have been modified through web-editor, runs Javascript.
Top Site**
- ListA
- Int Sites
- Ext Site Hub
- Ext SiteB
- LibraryC
List A is at s.sharepoint.com/sites/Top/Lists/ListA
External Site B is at s.sharepoint.com/sites/Top/Ext/ExtB
Library C is at s.sharepoint.com/sites/Top/Ext/ExtB/LibC
**Columns and Content Types for LibraryC are defined here
In O365 Admin I have selected Allow external users who accept sharing invitations and sign in as authenticated users.
The in SiteB I clicked the Share button on the site ribbon (next to the Follow button), and invited the external user, assigning them to Team Member (Edit).
Once the email arrived, I followed the link making sure to log in the with the correct Live account.
This took me to SiteB, and when I tried to navigate to the library, I got Page permission error.
I have tried removing and re-adding the users permissions. I have tried making the site/library permissions unique/inherit.
What have I missed?
Is this actually possible?
Has Sharepoint hidden some weird set of permissions for this?
Any help is appreciated.
