Hi,<br>we are using Microsoft 365 and having cloud based emails and no server control Kindly explain where its has to be implemented&nbsp;
</div>


<div>
Office 365 is just installed on the Desktop but email taken from Bigrock. Kindly explain in detials where it has to be implemented &nbsp;
</div>


<div>
You will need to inform your customers that invoices will only come from your domain name. Example, invoices@&lt;yourdomain.com&gt;<br>&nbsp;<br>Since you are using Microsoft365, it should help generate the needed spf record for your domain, but as Hayes Jupe mentioned, you should also look at setting up your DKIM and DMARC records after your spf is confirmed. I advise you work with your current DNS/Domain name provider to help you with this.

Hi<br>Can any tweak possible at desktop level &nbsp;to resolve this issue as we have Quick heal antivirus updated and windows 10 updated yesterday.

My bet is some of your users are getting compromised. On top of the controls that have been suggested here, you need a better password policy, along with multi factor authentication.

Email security isues

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
