What causes "HKLM\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Microsoft\SecurityManager" key?

Metered connection issue in Outlook. One of the many fixes for it is deleting this registry key, but what is creating this key? I have now removed this key 3 times, each time returning after the computer is rebooted for patching. Small client but I have about 15 identical setups here and only one having this issue.

Windows 10 Pro 20H2
Office 2019 Standard (don't know exact build but no updates were available)
Outlook connected to O365 mailbox

Hi @Jeremy m ,

From your description, seems that you are entering issue with "Metered Connection Warning",right?

According to my search, the metered network warning often happens when the system is connected over wifi networks like a mobile hotspot. While working on Outlook the message is generally displayed the network connection is a metered network.

If in this case, go to Start > Settings > Network & Internet, look for the network you are connected to, scroll down the screen and look for a metered connection.
Now slide the button towards off to turn off metered connection.

I have now removed this key 3 times, each time returning after the computer is rebooted for patching.

It is due to registry damage, it is recommended that you repair your office from the control panel.

Metered Connection is not turned on. Office has been repaired then removed using office scrub tool and reinstalled. My question is what is creating this key and how can I stop it from happening?

Hi @Jeremy m ，

Thanks for your reply.

According to my search, which is a known issue, for more content please see: Can't send or receive email in Outlook and "Metered Connection Warning" is triggered

Besides, there is no such registry value in my outlook2019 environment, so I think this seems to be more related to other programs or other settings in your computer, it is recommended you try other solutions.

So it is a known issue for some in O365, which I knew and have previously followed everything in this article, isn't possible that it is also an issue in 2019 and needs to be addressed by Microsoft? I just verified the computer is running Version 1808 (Build 10384.20023) which is the most recent. The key came back after a reboot today, no updates this time just a power outage in the area.

If this exact same issue happens in O365 and is fixed by an MS update for O365, it seems more plausible that this caused by something in the Office 2019 program and not another program.

Hi @Jeremy m ,

Thanks for your reply.
l haven't found out what creates this key.
As far as l know, some users with Office 2019 also encounter this problem. And the key would come right back up, on the next official update. So you can try the following workaround:

Open Regedit (Make sure you are admin)
Go to the path above in the reigstry.
Right-Click on “SecurityManager” and select “Permissions“
In the permissions window, look for the “Users” group and make sure Users have “Write” access.
Click the Apply to make sure the settings take.

Thanks Faery, setting the registry permissions as you recommended FIXED the problem quickly and easily! I have Office Pro Plus 2019 and my Outlook 2019 send/receive suddenly had this "Not Implemented" message, probably after an update ran overnight.

I had this same issue a couple months ago and nothing solved it except a painful uninstall/reinstall process which itself kept getting blocked by various error messages.

This registry solution avoids all that.
