Outlook email account not on Outlook 365 web version.

We've been using MS 365 for a few years.

And have made good use.

We've both retired this year and have reduced our use of MS365 considerably.

Still using Outlook, Calendar, Notes, Word, ToDo and contacts for personal use.

Regrettably Outlook integration has been extracted to the web.

But can't seem to get my BigPond.Com email account setup on the web version.

I've spent quite a bit of time trying to find any mention of it to no avail.

Any positive constructive help would be greatly appreciated.

Thanks in advance.
