FSLogix errors 26 and 41 in event log

Question

Hi all, new to FSLogix.

I am running FSLogix 2.9.8 and I have configured settings via Group policy.

In the event log i am getting the following errors

Event ID 26 - The required VHDLocations/CCDLocations setting is not present (One or more arguments are not correct.)
Event ID 41 - SessionId: 3, ErrorCode: 160, Detail: Logon failed, Please check logs and tracelogging and verify that the users disk was detached.

The user disk is successfully attached and detached every time - but these errors persist - and i cant work out why.

if i go into the registry to check the group policies are applied i see the following (which looks correct to me)

can anyone help shed some light as to why im getting these errors ?

I cant see any errors in the CloudCacheService<date>.log

Additionally, am i correct in stating that if i have Profile containers configured, that this includes office settings ? i dont need to separately configure Office 365 containers ?

Answer 1

Thanks - i was under the impression that configuring cloud cache - even if it was only using SMB for a local server - was the recommended configuration due to the reasons listed here

The error messages actually turned out to be that i had accidentally enabled Office containers, without defining a location for the office container.... once i removed that - the error messages went away.

Answer 2

Because you only set the Cloud Cache Directory and not the VHDLocation.
Cloud Cache is a second/backup location for your Profile. You have to set the first location as well.
Please also check if you really need cloud cache in your environment.
