Microsoft Outlook outgoing emails diverted to recipients spam or junk for hotmail outlook recipients
Hello We use Outlook as part of Office 365 in our business and recently we have seen that our outgoing emails to our staff and clients with hotmail or outlook email accounts are being diverted to...
first you need to check SPF,DKIM and DMARC is configured probably.
then check https://mxtoolbox.com/blacklists.aspx if your domain is blacklisted.
and try to get Message header and analyze it.
If I have answered your question, please mark your post as Solved If you like my response, please give it a Like Appreciate your Kudos! Proud to contribute! 🙂 |
- Thank you for taking the time to respond. I have checked the blacklist and our domain is not present. We do not have access to the GMAIL server which is used for several private offices all under the same domain name. This is managed by a 3rd party IT provider. I have no idea what SPF, DKIM or DMARC is or their relevance. Are these entries on the DNS?
- Yes DNS Record,
ask one of your client to send you message header of copy of one mail from junk folder and try to analyze or paste it here- Thank you. I have obfuscated the domain name to 'domainxxxxxxxx.co.uk' and my outlook test address
