We are having some emails to our webmail accounts being rejected as spam and not being delivered at all. This appears to mean that we can't add the sender to a safe sender list.
Today this happened with an important message from support@solaredge.com. Our Plusnet user id is Adapt and the email addresses involved are david@adapt.biz and mary@adapt.biz.
How can we prevent this from happening, please?
I've copied the information that the sender received below (some invalid HTML has been removed by this site)

support Office 365 adapt.biz Sender Action Required Messages suspected as spam
How to Fix It Try to modify your message, or change how you're sending the message, using the guidance in this article: Bulk E-mailing Best Practices for Senders Using Forefront Online Protection for Exchange. Then resend your message. If you continue to experience the problem, contact the recipient by some other means (by phone, for example) and ask them to ask their email admin to add your email address, or your domain name, to their allowed senders list.

More Info for Email Admins Status code: 550 5.7.350
When Office 365 tried to send the message to the recipient (outside Office 365), the recipient's email server (or email filtering service) suspected the sender's message is spam.
If the sender can't fix the problem by modifying their message, contact the recipient's email admin and ask them to add your domain name, or the sender's email address, to their list of allowed senders.
Although the sender may be able to alter the message contents to fix this issue, it's likely that only the recipient's email admin can fix this problem. Unfortunately, Office 365 Support is unlikely to be able to help fix these kinds of externally reported errors.
