Outlook version
Outlook 365 64 bit
Email Account
IMAP
Operating system::    Win10
Outlook version:     Classic Outlook 365
Email type or host:    IMAP via gmail
My LOGS runneth over for some reason, (3GB log files daily: C:\Users\MyUserName\AppData\Local\Temp) and the setting for Outlook troubleshooting/logging - option is grayed out here: Outlook Classic 365 > File > Options > Advanced > Other >

I don't remember clicking that box. And now I can't un-click it. So for now I am manually deleting those big log files every day or three.

Pardon me if this has been covered, I looked and could not find a thread which addressed this issue.

I've been to a few random troubleshooting articles on the Internet that suggest editing the registry and I tried a few "tweaks" but the problem persists. One article ( Redirecting ) suggested that OL must "see" a fresh Profile that can only be established by deleting the profile keys at \HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Profiles
I haven't done that yet.

I've never made a new Profile but it seems easy enough, although some other users with this issue said, "...just making a new profile did not work...". They had to edit the registry as I mentioned above. Other folks tried adjusting/deleting/making other keys, mostly without much luck.

Any suggestions before I go hacking around any further? Thank you for your time.
 
This registry value is what gets set by the File > Options > Advanced -> Other. Enable troubleshooting logging checkbox in Outlook. Exit and restart Outlook.

How to enable transport logging in Outlook - Outlook

HKEY_CURRENT_USER\Software\Microsoft\Office\NN.0\Outlook\Options\Mail
DWORD: EnableLogging
Values: 1 = logging enabled, 0 = logging disabled
Restart Outlook
 
The key is global, not per profile, so a new profile won't help.

if you are using one of the Insider builds, it is enabled as part of the insider program. You can delete the log files and Outlook will recreate the logs. (Close Outlook first so you can get all the logs.) Or turn off insider.

As an FYI, I will occasionally go into the temp folder and delete everything in the temp folder - a few things won't delete and that is fine.

Also, some of the files are related to Search - there is a reg key that will kill them. But... any of those files older than 5 days should be removed automatically.
