KIS 21.3.10.391(m) on Windows 11 Pro, fully updated. Since 17/1 some MS services will not communicate to their servers. Including Outlook desktop/Copilot/One Drive/Teams. Does not apply to the same apps running in a browser. Pausing KIS initially did not appear to change behaviour but after running MS defender and pausing KIS again, apps can communicate until KIS is switched on. A recent windows update on 16/1 (24H2) was done just before issues appeared.Issues appear to relate to server authentication.No error logs from KIS,no sensible error messaages from the O/S. Appears to be some incompatibility with MS protocols.

A similar problem I had 2 years ago was cured by reinstalling KIS. However I see now there are some post to switch to Standard. So please advice what is recommended here and how to implement.

@Rutile Welcome 

In the meantime Kaspersky Standard 21.20 has just been released ?

 

As @Bernyposted, please migrate Your KIS to the new product line, current version K. 21.20.

Hello @Rutile, 

Also, to migrate to Kaspersky Standard, use the latest version: https://www.kaspersky.com/downloads#update-product.

It's (your) choice whether you uninstall the old software (KIS) before installing Kaspersky Standard - we prefer to make a fresh start - it's personal choice - however, you may wish to *Export* KIS Settings * before* uninstalling, so (you) can *Import* into Kaspersky Standard. 

• KIS - Export, read: How to export application settings.
• Standard - Import, read: How to import settings.

Thank you?

With an 'on-top' install  Kaspersky Standard will import your License + KIS settings + Bank accounts.
Also after installation , please update Databases  + Reboot 

Thank you so much for the info.
