Find below the two-step process for enabling global logging on Outlook 365, the latest Outlook edition. The steps are also similar for Outlook 2021 (16.0), Outlook 2019 (16.0), Outlook 2016 (16.0), Outlook 2013 (15.0), and Outlook 2010 (14.0).

You need to perform both of the below-mentioned steps to generate a log file for the error you’re experiencing.

1. Turn On or Off Global Logging on Outlook Options

  • Open the Outlook app on your Windows PC.
  • On the ribbon menu, click File and then select Options from the left-side menu.
  • In Outlook Options, select Advanced on the left side.
  • Scroll down the right-side menu and find Other.

  • Hold the Windows Key, and press R to bring up the Run window.
  • Type regedit and select OK to open the Registry Editor.

    Honestly those log files are useless. The problem is that Microsoft holds the symbolpdb files in order to decipher the ETL files. So you have to send the etl to Microsoft to review.

    No help. Every time I move something from one folder to another, an item is logged in the Synchronization Error folder (popped up one day and has been filling up like crazy ever since).

    This page doesn’t contain enough information to be useful in diagnosing Outlook problems. For example, when I checked my %temp% folder, I found that it contained eighty-nine log files, and there was nothing apparent from the file names that indicated which were Outlook logs and which were not. It’s not reasonable to expect anyone to open eighty-nine log files and foe each file, try to discern from the log entries whether the log file was generated by Outlook, It’s not enough to simply say that Outlook log files are stored in the user’s appdata\local\temp folder. This FAQ page also needs to provide some guidance for identifying the Outlook log files in that folder..
