I do a monthly newsletter for a non-profit. I use Win10 and MS Outlook. I send them via 2 distribution lists of approximately 25 email addresses each. One recipient uses galaxy s7 with gmail account and does not receive the email with pdf newsletter attached. I have confirmed her address, deleted her address and re-added it, both individually and in the distribution list. She can receive the newsletter just fine if it's mailed only to her...but not when it's sent from the list. I don't understand what might be causing this. I don't get any mail-failure notification. Everyone else on the list is fine, even other gmail users. She is the poster woman for a sweet old lady, but does NOT understand anything about computers. She took her phone to a big box computer store, and they told her there is nothing in her spam folder (something I'd asked earlier). They checked Settings and said it SHOULD work. There might be something simple that I'm not seeing...and I'm not technical myself either...but right now I'm clueless about how to help her.
Any help would be appreciated.
