F-Secure Internet Security slows down communication between Office 365 Outlook and OneNote 2016

From Office 365 Outlook you can send elements such as calendar entries, e-mails etc. to OneNote for filing. By installing F-Secure Internet Security, the transfer of items takes up to one minute. Without F-Secure it takes a split second. Where can I adjust the settings so that F-Secure is not a barrier?

    I am only an F-Secure user (their home solutions).


    I think that you could try next:

    -- repeat such a trouble (delay with receiving).

    -- create a diagnostic file (fsdiag: https://community.f-secure.com/t5/Common-Topics/How-do-I-create-an-FSDIAG-file/ta-p/18190)

    -- to contact their official Support channel. For example, web-chat:



    Then Support agents with an opportunity to perform an investigation.

    Maybe it is possible to suggest something as a workaround or fix. Or maybe something is possible to change with solution design internally.


    Otherwise, maybe this delay is kind of limitation of multiple layers of protection. 'Network'-based check, 'File-system'-based check or something else. Just like a common resource usage.

    However, I think that there can be (or should be) optimizations against it.

    Thanks for the tips. I have contacted F-Secure support.

    In excluding the local storage files and folders for Outlook and OneNote from real-time scanning, the communication works much faster. The folder paths in question would be:

    C:\Users\<Your_Username>\AppData\Local\Microsoft\Outlook; and

    C:\Users\<Your_Username>\Documents\OneNote Notebooks.
