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..
