Error message, unclear what is meant

Since the latest update I continuously get the error message:
Outlook : an error occurred
[IMAP] Failed to LIST server folders (Server Unavailable. 15).
No clue what this is about, nor why the error message.
Operationally eMclient seems to work: i receive emails, I can send emails.
Thanks for the support

Hi @nefilim

Avast doesn’t only cause problems with email!

Avast Collects and Sells Your Browsing History!

By default, Avast collects your web browsing activity and offers it to marketeers
through their subsidiary named Jumpshot.
Companies who pay Avast/Jumpshot can view full “clickstream data” to see what
Avast users are doing online.

The data collected is so granular that Jumpshot clients can view the individual
clicks that Avast users are making on their browsing sessions, including the time
right down to the millisecond.

The collected data is linked to a person’s name, email and or IP address.
Each user history is assigned to an identifier called the device ID, which
persists unless the user uninstalls the Avast antivirus product.

So why would you have it on your system?

As an alternative Microsoft’s Windows Defender, which is integrated into
all versions of Windows 10, and of course it’s free.
Microsoft’s antivirus doesn’t have an agenda beyond keeping antvirus
off your computer.

It doesn’t track your web browsing!
