Hi,
I'm looking for advice/help in regards to some spam emails we've been receiving within our organisation.
At the current time, we are using office365, however the CEO in our company keeps getting targeted via spam. Numerous employees within our organisation are receiving emails from our CEO without him knowing, the email looks like it has come from the actual domain address of our company from our CEO, but the reply address is different. Sort of like masking our actual users real domain email address over a free email account like gmail. The reply address being the gmail account.
These sort of emails vary, from asking for wired bank transfers to asking for help.
Is there anyway of stopping this within our office365 environment?
