Office365 Outlook advanced ETW always activated in RDS-farm RRS feed

  • Question

  • We have two remotedesktop servers with Microsoft Office.

    OS: Windows Server 2019
    MSO: 365 ProPlus shared licensing

    Both of the servers have huge I/O-load because of outlook.exe working in userprofile\localappdata\temp\..\outlook logging\OUTLOOK-date-time-v2.etl

    Relevant threads:

    No outlook has the "Enable troubleshooting logging"-option selected. No Registry Keys were set. It even happens for a user that I just created with 0 data and 0 mailstore. There was no "debugmode" or anything similar selected when MSO was deployed via xml.

    It happens on both servers. I cannot get it to stop logging. Is there another way?

    We have a similar installation (WinSrv 2016 with one RDS with MSO 2016 Standard). There we do not have any problems with I/O-traffic because of logging

  • Does it happen to all clients on RDS? Only happen to Office 365 client?

    How do you deploy the installation of Office 365?

    We can run following command in Command Prompt to check the policy on the client:

    Gpresult /H GPReport.html

    The report will be normally saved in User folder: C:\Users\<username> Check if any policy was enabled to force Outlook logging.

    Besides, if no registry was showing in that path, we can manually create these keys to disable them. Set the value to 0:

    (Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.
