Greetings.
Back in the 90s a company created a domain name, created a group of email addresses and launched a website. Over the years the web host has been changed. Originally the email was handled by the web host and each user had Outlook on their computers for access.
Some years ago, the company changed over to email being handled by Microsoft 365 admin. It appears when that happened not all the email addresses were added into MS 365 as active users. Two emails, one that is their contact and ask for info address using info@company.com, and one that was for the outside tech support guy as in tech@company.com.
"info" was originally set up to forward to the account manager who had an email with "company.com" which is an active user in MS 365. "tech" is forwarded to an email address with a different domain name, as in bozo@techcompany.com.
Both of these email addresses are working fine. Forwarding is functioning without issue.
Neither of these email addresses exist anywhere in MS 365 admin. Not team, group or share areas.
How do I find out what entity is capturing these two email addresses and forwarding them to the correct addresses.?? Then adding them to MS 365 admin.
