What you’re seeing
- Users sign in to a blank desktop with default wallpaper and none of their files, shortcuts or settings.
- Windows reports that you've been signed in with a temporary profile.
- Outlook sets itself up from scratch and Teams asks for sign-in every session.
- Anything saved during the session is gone at the next sign-in.
- FSLogix logs report that the profile container couldn't be attached or is in use.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The file share holding the profile containers is unreachable or full, or the session host can't authenticate to it.
- Share or NTFS permissions don't allow users to create or open their own profile disk.
- The user's profile disk is still locked by an earlier session that didn't close cleanly on another host.
- The profile container is corrupt or has reached its maximum size, so it can't be mounted.
- A local profile for the user already exists on the session host, and FSLogix is configured not to replace it.
- Identity-based access to an Azure Files storage account stopped working after a password, key or domain change.
Why it matters
On shared desktop environments, the profile container is everything a user expects to see: their desktop, Outlook cache, browser data and app settings. A temporary profile makes the session nearly useless, and any work saved to it disappears at sign-out, so people lose files without realizing it. When the cause is the storage share, every user on every session host can be affected at once, turning a single fault into an office-wide outage.

Frequently asked questions
Have the user's files and settings been lost?
Usually not. The profile container is typically still on the file share and simply failed to attach. The real risk is work saved into the temporary profile, which is discarded at sign-out.
Does this affect everyone on the server or just one person?
It depends on the cause. A locked or corrupt disk affects one user, while a storage or permissions problem can hit everyone. The engineer confirms which before changing anything.
