Welcome to the Microsoft Q&A Platform and thank you for your question in here!
Based on your description, it seems you are encountering an issue where FSLogix is not recreating a profile for a user after manually deleting the profile disk from the Azure file share. Instead of triggering FSLogix to generate a new container, the session gets stuck on a black screen with a "Please wait" message.
This behavior typically suggests that FSLogix is encountering issues during the profile creation or mounting process. Since it worked successfully for another user, the problem may be user-specific or related to remnants from the previous profile.
I would like to recommend a few troubleshooting steps that may help fix the issue.
1.Ensure Local Profile Is Removed Completely
Verify that the local copy of the profile (under C:\Users) for the affected user has been deleted.
Also, check HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList in the registry and remove any stale entries associated with the affected user’s SID.
2.Check FSLogix Logs
Review the FSLogix logs located at: C:\ProgramData\FSLogix\Logs\Profile Look for any errors or failed mount attempts that might explain why the profile isn't being created or attached.
3.Verify Share Access
Log in to the session host as the affected user (or an admin) and test access to the profile share: \<fileserver><profileshare> Ensure the user has both read/write NTFS permissions and Full Control share permissions.
4.Confirm “Delete Local Profile When VHD Should Apply” Policy
Make sure this policy is enabled to avoid local profile conflicts:
Computer Configuration > Administrative Templates > FSLogix > Profile Containers > Delete local profile when VHD should apply: Enabled
5.Check Profile Storage Quotas or Locking
Ensure the user’s VHD(x) isn’t locked by another session or blocked due to storage quotas.
Please let me know how it goes, I am happy to assist further if needed. Wishing you a successful resolution and a great day!
