Similar to James question above has anyone some across increased writes in PVS cache for Office logs? We are our write cache fill up due to Office diagnostics/Outlook Logs constantly being written. We are using FSLogix profiles and can see in C:\Local_Username\Temp\random number\ two folders: • diagnostics\Office App (Outlook, Word, Excel) = containing 5 * 16MB rotating files called App_random GUID • Outlook Loggin = Office App_GUID.etl We have triple checked and all logging is disabled in GPO, we have even used some forum posts suggested registry entries to disable logging and nothing has helped.

Have you checked this post? https://www.reddit.com/r/sysadmin/comments/q6sesu/office_2021_your_privacy_matters_disable_via_gpo/ "HKCU\Software\Microsoft\Office\16.0\common\Privacy\SettingsStore\Anonymous" -Name "OptionalConnectedExperiencesNoticeVersion" -Type DWord -Value "2" "HKCU\Software\Microsoft\Office\16.0\common\Privacy\SettingsStore\Anonymous" -Name "FRESettingsMigrated" -Type DWord -Value "1" "HKCU\Software\Microsoft\Office\16.0\common\Privacy\SettingsStore\Anonymous" -Name "RequiredDiagnosticDataNoticeVersion" -Type DWord -Value "1" "HKCU\Software\Microsoft\Office\16.0\common\Privacy\SettingsStore\Anonymous" -Name "OptionalDiagnosticDataConsentVersion" -Type DWord -Value "1" "HKCU\Software\Microsoft\Office\16.0\common\Privacy\SettingsStore\Anonymous" -Name "ConnectedExperiencesNoticeVersion" -Type DWord -Value "1"

Ooo no I havnt, thank you, will take a look.

This could be something for you then: https://learn.microsoft.com/en-us/outlook/troubleshoot/performance/outlook-exe-log-file-in-temp-folder-consumes-too-much-space https://learn.microsoft.com/en-us/mem/intune/remote-actions/collect-diagnostics

Yeah we looked into that post and we dont have the debug key set.

I have 2 or 3 x 16MB files under %tmp%\Diagnostics\Outlook . How many files do you see? how big ? What Office version and OS?

We have anywhere from 5-8 files all 16MB. Using Office 365 Apps for Enterprise 2402 (build 17328.20550) on Server 2019.

I have the same actually, the longer you have the office appa running, the more files you have. Only 2 are being actively written, other are archive.

Strange that they are being generated even though we have not specified any logging/diag to be enabled.

I think it is enabled by default but that's something that can be tweak as I have another device from my enterprise and the logs are 20MB and there is an addition folder. I'll keep an eye on this as it does add up quite a bit of logs!

@Ryan Swanepoel did you ever figure out a way to disable those logs? Seeing the same thing here.

Hey @Steve Noel I didnt unfortunately, our issue turned out to be some users having very large OneNotes for which the cache was being excluded in our FSLogix redirections.xml Everytime they logged on and opened their OneNote it would re-cache the content and blowup our write cache, we ended up removing it from our redirections.xml and including it in the profile containers. But I never found a way to stop the large amounts of office logs.

ah, no prob. Appreciate the response
