Undeliverable:???
- Update(?): I read somewhere there is an update in progress, which will go through July 15, 2022. I will have to wait until after that date and check again. MEANTIME, though, I (LUCKILY) have another source to send, reply to, and forward(?) messages. Inconvenient, but at least "it" is there!
This is complicated because the recipients marked your messages as SPAM and now you are a blocked sender and blacklisted.
The combination of Gmail and Outlook is unlikely to matter because you can receive mail, but you can not send anything - write if I understand correctly?

Yes because IP. your computer is blacklisted for spam.

- OMG! "This" is the message I get: "Step 1: Invalid email address or IP address. Please provide your email address and the IP address you want to delist so that verification can proceed." IDK what to do! Nothing seems to be helping- other than you (Andrzej1). Thank you for all you've done/ are doing.
- ask your friends -> who can verify the information you need to help you fill the formula it is complicated so only so you can fix it
