Microsoft Outlook has a logging feature that’s used to troubleshoot technical issues. It keeps a log file of email and calendar events in Outlook. Here’s how to enable or disable this feature.
Outlook 2016, 2013 & 2010
- Select “File” > “Options“.
- Select “Advanced“.
- Scroll down to the “Other” section and check the “Enable troubleshooting logging” option.
Outlook 2007
- Under the “Tools” menu, select “Options“.
- From the “Other” tab, select “Advanced Options“.
- Check (enable) or uncheck (disable) the “Enable logging (troubleshooting)” box.
- Select “OK” twice and restart Outlook. Logging Enabled should appear in the title bar.
FAQ
Where is the Outlook log file saved?
For all versions of Outlook, the log file is created at C:\Users\user name\AppData\Local\Temp\Outlook Logging\OPMLog.log in Windows 10, 8, 7, and Vista. For Windows XP users, it will be created at C:\Documents and Settings\user name\Local Settings\Temp\Outlook Logging\OPMLog.log
For more information, see What is the Enable logging (troubleshooting) option?
I reboot Windows every day. You have to, or it doesn’t run correctly. (Well, it doesn’t run correctly to begin with, as is the case with all Microsoft software, but that is another story). I clear the temp file after rebooting each day. If you try and clear it before you shut down, many of the temp files and/or logs will not delete because they report being in use. Using Word or Excel generates tons of “tmp” files (much more so now that I am using Office 2016) and when you close those programs you cannot delete the temp files until rebooting. A typical example of the “unfinished thought; by all means ship it and let the customer’s straighten out the bugs” poor design that all Microsoft software products exemplify.
The Outlook Logging is always an entry in the Temp folder. The option was NEVER enabled and the logging still appears.
I just put new solid state disks in and I want to eliminate this. and any other, unnecessary disk writing.
Any idea what else is keeping the Outlook Logging enabled?
This doesn’t work. Outlook 2013 creates 20K+ files over a period of a few days. Win 7.
I have turned off the logging but still the log file is created and it has a massive size of almost 25GB.
