Hi guys. So my Microsoft exchange business email acc got hacked a few weeks ago. I was able to retrieve it and re-secure everything (scanned for malware and changed pw’s etc). BUT the hackers activated a setting where certain email contacts of mine (clients) are blocked from my main inbox; emails that they send me do not show up in my normal inbox. I have to search the clients email address and then I can find emails they recently sent me. Does anyone know how to fix this. Thanks!
This is most likely a common attack that is used where attackers set up rules to autoforward and delete certain mails when they come in. Searching may be finding them in your deleted items? Check your mailbox rules ASAP to ensure there is no forwarding in place!
