Hello Microsoft team, our company is running Office 365 Small Business Premium, we transferred our accounts from a .onmicosoft to our own domain I completed the whole process for Email handling only, so our Webpage is being hosted on another provider, while our emails are managed by Outlook.com
Recently I've been getting NDRs on some emails, one of which reported the cause as: Failed to Meet SPF Requirements, I would like some assistance in solving this issue because my emails are not getting through.
Please send me a Private message to attach the complete NDR.
Thank you very much.
