While I disagree that Outlook is a “less secure app”, we have to go with what Google says, not what we think.
Regardless if you are getting this pop up when trying to access your mail, the patch is easy.
First close Outlook, you may have to use “Task Manager” to stop it.
DANGER WILL ROBINSON – You will be editing your registry, so be aware.
Let’s backup your registry. We will click the Windows ‘start’ button in the lower left corner of your screen (middle left of Windows 11) and type in “regedit”.
Once the registry editor opens go to the upper left corner and click on “File” and then “Export”. Windows will open a new window. I strongly suggest you navigate to your “C:” drive. By exporting it there, if an issue occurs recovery is easier to access. So in the “Save in” area (top center of the window) select the drop down and select “Windows C:”
I would give it the name “regbu” for registry backup. This may take a minute or two to complete. When the hour glass is gone, it is done.
Now we need to navigate the left column of the registry to the following by clicking on the arrows.
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\ FEATURE_BROWSER_EMULATION
Find the REG_DWORD OUTLOOK.EXE and double-click to edit. Select “Decimal” (by default it opens to hexadecimal) and change the value to “11001”.
Once you have changed the decimal value to 11001, select “ok” and then close the registry editor.
Now you can open Outlook and all should work.
Until we meet again, have a virus free week.
