Sugar,

A few things come to mind.

I'm not sure how this works and whether it's applicable to your group, but if it's a group created with the limited-membership feature (after Feb-2021), could it be you've hit the limit?

Have you tried emailing her directly from your personal or the group-owner address?

Has she checked to make sure the emails are not going to her outlook.com spam/junk folder?? It's a new outlook account and maybe the spam filter is overly aggressive.? If there are groups.io emails in there, she needs to mark all of them as Not Junk and tell outlook to not put them there anymore.? IIRC Outlook will move them automatically into the inbox but if not, she needs to do that too, there should be no groups.io message left into the spam/junk folder.

Otherwise, if there are no groups.io messages in her junk folder, then it must be a typo somewhere, I don't know what else could cause this.

Cheers,
Christos
