Question 1

What is the recommended Azure Files tier for FSLogix?

Accepted Answer

Premium SSD Azure Files is recommended for any production FSLogix deployment. The IOPS and latency characteristics of Standard HDD shares cause logon delays and occasional VHD attachment timeouts under concurrent peak load. The cost premium over Standard is typically $3-8/user/month depending on container size.

Question 2

What is the minimum FSLogix container size?

Accepted Answer

A minimum of 30 GB per user is recommended for Office-heavy environments. Task workers using only browser and minimal local applications can use 10-15 GB. Containers that fill to capacity cause the profile to detach mid-session, resulting in data loss.

Question 3

Should we use Profile Container or Cloud Cache?

Accepted Answer

Profile Container (standard VHD-on-share) is recommended for most environments. Cloud Cache is appropriate when active-active multi-region redundancy is required, but it adds complexity and increases storage costs by 2x. Unless multi-region failover is a hard requirement, Profile Container is simpler and more performant.

Question 4

How does OneDrive interact with FSLogix?

Accepted Answer

OneDrive Known Folder Move should be enabled alongside FSLogix to sync Desktop, Documents, and Pictures to SharePoint Online rather than storing them in the profile container. This keeps container sizes manageable and ensures these folders are accessible even if a profile container is unavailable.
