As the title suggests, does Office 365 offer a way that users in a company have their emails configured so that if they receive an external or internal email, there is a cue or message that automatically tells them so?
We want our users to be aware what emails are external and what are internals. Perhaps even just tagging external emails only with the cue message.
A sample message in the email body would be:
**The e-mail below is from an external source. Please exercise caution before opening attachments or clicking links.**
The wordings can change, but the idea is what I'm trying to convey here.
Also we would like to be able to distribute this configuration to all of our company's population, not just 2 or three people only.
