Hi, I'm having a problem around understanding the required permissions to assign a task to a person in a scenario where the person does not require access to the parent site where the library ask resides

Scenario:

Site: https://sharepoint.com/sites/team      - Permissions for UserA = NONE (the user does not need to access the site in general)

Library: https://sharepoint.com/sites/team/DocLib    - Permissions for UserA = NONE (the user does not need access to the source document, from which the workflow runs)

However, a workflow within the Document Library above could trigger a task for "UserA",  who would then need to complete their task (the task would be https://sharepoint.com/sites/team/WorkflowTasks)

Due to the requirement that non-site members may require access to their task, I have tried to give "DomainEveryone" = Contribute permission to the https://sharepoint.com/sites/team/WorkflowTasks list.

However, I still get this issue.

(in the above scenario, UserA still has no site access, but is given direct access (contribute) to the WorkFlowTasks library)

Am I missing something obvious? I would think that having contribute access to the task list would be sufficient, but it is not

If I give Everyone = Contribute access to the entire site, it works. However, this is way too much permission. I would like to keep permission to a minimum for non-site members to access tasks assigned to them

Thanks

Carl
