Avast One - invalid email certificate in Outlook 365

Avast One
1

I keep getting the following error message when I launch Outlook 365 on my PC

[i]"The server you are connected to is using a security certificate that cannot be verified.

A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file"[/i]

If if select “Yes” to “Do you want to continue using this server?” it connects and downloads the emails - otherwise nothing happens.

When I view the certificate it says that it was issued by AvastWeb/Mail Shield Root, with a validity from 16/05/2022 to 14/08/2022 - but I can find no options to update this within Avast One

HELP!!!

Hi,

Can you attach a screenshot of the error message, please? https://support.avast.com/en-ww/article/Create-screenshot

Also, go to the folder [b]C:\ProgramData\Avast Software\Avast[/b] (the ProgramData folder is hidden), double click on the file with the name wscert.der and see what that expiration date is.
