what is your guys optinions/experiences with running FSLogix profile containers from a Windows Server Failover Clustering (WSFC)? The only thing from Microsoft is that Continuous Availability should be enabled on the share https://learn.microsoft.com/en-us/azure/azure-netapp-files/enable-continuous-availability-existing-smb

just updated a German Server 2019 to 2601 CU1 Log is full of errors and profiles are not dismounted.

[07:09:54.068][tid:0000122c.00000370][ERROR:00000057]  Failed to query activity id for session 2 (Falscher Parameter.)

found some users on reddit with the same issue..

Enlighten me on RoamIdentity... chatgpt is saying its not on or is missing for FSLogix (it might be, will check soon)..but at some point, and maybe this started happening when I upgraded FSlogix version from a pretty old one a few months ago, that users are now frequently having to re-authenticate to office apps (outlook/word, etc).. requiring a Duo MFA prompt, etc.

Anyone seeing issues with Excel 2016, OneDrive and FSLogix. Unable to open documents. EOL etc.

I’m trying to design high availability for FSLogix profile containers and folder redirection in a small on‑prem environment. I’d like to mirror the “Multiple SMB Locations with Single VHD Path and DFS” approach described in this article by James Kindon: https://jkindon.com/architecting-for-fslogix-containers-high-availability/ Is anyone doing something similar? If so, what are you using to replicate the FSLogix containers and redirected folders between SMB locations (DFS‑R, storage replication, third‑party tools, etc.)? In particular, does anyone have experience using Dell RecoverPoint to replicate FSLogix containers and/or folder redirection data to a secondary site? How has it worked out for you in terms of performance, consistency, and failover/failback?

is it still advisable to use separate container for profiles and office data? or has everyone been just using the profile container. I always kept them separate, but not sure if that is really being done anymore. i can't find what MS recommends anymore. i saw one link where it said to use one profile container for both profile and office data..just wondering what everyone else thinks..thx

I see a lot of posts about the "10 hour FSLogix" issue with kerberos ticket time. Our org is asking (telling) us they are moving to 4 hour kerberos tickets. Is that an "old" issue, or still something that is a problem? If it's still a problem, is it a "it might happen, might not" or a "oh, just hang it up, after 4 hours everyone's session is toast" kind of issue?

I've updated to the latest FSLogix on a 2019 RDS farm. I'm battling tokens, etc. I have RoamIdentity = DISABLED (per some of your comments). However, some users (I'm not sure its all) are getting "Your privacy matters" screen when they open outlook everytime, or prompted for MFA, etc. Need to solve this once and for all. I'm not using Office containers either, per other recommendations.

Can anyone sanity check me here and have a look under HKLM\Software\FSLogix\Profiles\Sessions\[SID] and see what VHDOpenedFilePath or VHDRootFilePath is set to? I've got some oddness showing and wondering what it is

It is just the unc path to the profile .vhdx Same location for both.

So got a customer who is using Cloud Cache. They seem to think that Cloud Cache means there is a copy of the VHDX taken on a local disk and there is therefore zero I/O to the network at all which then just "syncs back" at logoff. AFAIK this is not how Cloud Cache works - it just caches "hot blocks" locally and then uses them in outage scenarios, IIRC. Or has it evolved somewhat and I am missing the point? They certainly seem convinced that Cloud Cache is some miracle "local profile" tech

I am migrating users from W22 to W25. Users get a new UPM profile but keep their ODFC container used for EXO cache file. Pilot, and for a while all good but now it seems some users are seeing oddity like emails read are not read anymore, email moved to a folder back to inbox, etc. hard to get enough evidence from SD ... But it seems for most cases there is a correlation with the migration. Almost the same O365 version between W22 and W25, one minor version behind on W22, W25 up to date. So do you reset your ODFC when you migrate? Thanks!

Hi all has anyone run Aaron parkers fslogix profile clean up scripts either the logon/logoff script or the profile cleanup script which is ran when users are not logged in and the container is not in use ? . The scripts will delete the data but does anyone know if it will compact the containers to free up the white space? I have a bunch of data in a single location within multiple users profile containers i need to delete and these scripts are perfect but i need to reduce the size of the users profile containers and free up space on backend storage https://stealthpuppy.com/fslogix/profilecleanup/

Since yesterday several of our customer's monitoring alerted us, that Fileserver drives, which host FSLogix VHDX files, see significant usage growth. We had to emergency expand several drives today and yesterday, to stop a potential Citrix outage. Anybody else seeing significant VHDX growth in the last few days?

Did anyone ever encounter problems with programs updating/doing automatic file renamings inside an FSLogix Profile and know the root cause and solution to this? We have a legacy application that lives in the user’s roaming profile %APPDATA%\Prosytec\WMSClient.exe The program runs great. No issues. BUT its weird Update-Process occacionally bricks the programm: It updates itself when starting WMSClient.exe by downloading WMSClient.upd, renaming the running/current WMSClient.exe to .old, renaming .upd to .exe, and starting the new version. This works most of the time, but sometimes the application crashes during the update. In one case, the rename to .old repeatedly failed with error 650, referring to an invalid device object or a device object not attached to the specified volume. In a later case, it crashed even earlier, immediately after WMSClient.upd appeared, before .old was created. Now why do I post this in the fslogix channel? I moved the whole application folder from AppData to the user’s redirected Documents folder. That location is not part of the FSLogix container and is hosted on a Linux Samba file server. Since then, the application appears to update and run correctly.

Anyone had luck hiding Copilot from start menu with FSLogix? We're trying to avoid a separate image in our PVS environment.

for folks using CItrix and fslogix on prem and using outlook/onedrive auth'ing to M365 are you adding a HKLM reg key in your non persistent images for LoadCredKeyFromProfile? this key is new to me...

FSLogix vs CPM What are your experiences with both profile solutions? We are currently using both -> CPM for published applications and FSLogix for Desktops There was a need for this in the past, due to technical limitations of both solutions, but as far as I am aware these limitations are gone and both solutions are working pretty similiar. As we are only using Citrix for our VDI maybe switching everything to CPM would be an idea? Which solutions do you prefer and do you think we would get an benefit from standardizing our profile solution?

Hi everyone, Has anyone found a solution to the repeated AppX package registration during logon on Windows 11 non-persistent VDIs using FSLogix? Since the AppX registration state is stored at the machine level, FSLogix re-registers around 100 packages at every logon. In our environment, this blocks the Winlogon process for approximately 15–25 seconds. We've tested different FSLogix versions and also tried setting InstallAppxPackages=0, but neither had any noticeable impact on the overall logon time. Citrix UPM already provides a solution for this issue using a persistent AppRepository disk:

With the Enable AppX package load acceleration policy enabled, Profile Management creates a virtual disk container for each machine to store the UWP app registration data. This feature accelerates the loading of UWP apps and prevents data loss on machine restarts.

Reference: Enable UWP app load acceleration | Profile Management 2603 Has anyone encountered the same issue or found a comparable workaround for FSLogix? Any insights or suggestions would be greatly appreciated!

I'm not sure I like the part about "multi-user environments" as it seems to exclude single-session? [Windows Explorer (Known issue)] Fixed This update fixes an issue that affects Windows Explorer in multi-user environments, such as Azure Virtual Desktop and FSLogix. After sign-in, Explorer.exe might fail to start or repeatedly crash, causing a black screen. October 13, 2026—KB5127648 (OS Builds 26300.9711, 26200.9711 and 26100.9711) | Microsoft Support

Anyone got a solution for the slow login to OneDrive? The users are even presented with the "OneDrive not logged in" before it finally decides to go ahead and sign in. I noticed this from version 2601 so most of my customers still run 2506 because of this.

For non-persistent machines, whats your average dehydration period for onedrive files? 1 day? 7 days?
