Applies To

  • Outlook 365 Virtual Office meetings add on
  • Chrome

Resolution

This is due to a recent Chrome update, where they changed the default behavior (enable) of the SameSite by default cookies flag.

To resolve this issue, we need to disable that flag:

  1. Open Chrome and typechrome://flags/
  2. Search for SameSite by default cookies flag.  It will be set to Default (enabled). Disable this option and re-launch Chrome.
  3. Log into the VO meetings plugins, it should be successful.

Additional Information

8x8 is working on modifying the add on so that it will work with Chrome's default configuration. For now, disabling the flag will resolve the issue. Other browsers work without additional modification.
