Frequent Hotmail server failures

Seeing the red triangle frequently in eM Client.

Info:
OS: Windows 10
eM Client: 8.2.1237
No VPN software
No antivirus except Windows Defender

Things Ive tried:

  1. Remove and re-add the account
  2. Add the account as Exchange instead of IMAP (unsuccessful as it just goes into a “enter your password loop” and never completes)

Error in log:
