I hear a lot of people say that they don’t find Office 365 anti-spam filtering as good as other providers. My reply to that is – “Have you ever actually gone in and configured the settings from what is there by default?”. Unsurprisingly, the answer is always No.
The out of the box spam settings you get with Office 365 are designed for the “average” and probably configured for the least business interruption (i.e. less aggressive classification of what is spam). Thus, to get the optimal level of filtering you desire, it is recommended that you go and set the options the way that you want.
I have configured my tenant for the way I wish to handle spam but that is probably not exactly the best place for people to start. So with that in mind I thought that I’d call on the power of the crowd and offer up a survey were people can nominate what they consider to be major indicators of spam, based on the policy options that Microsoft provide. You’ll find that survey here:
which I encourage you to fill out and share with everyone else.
The idea is that once the results are in I report back on an overall “best practices” starting policy that the majority would feel comfortable with. I can then also show you how to exactly configure that in Office 365.
So please take a moment to complete the survey and share you expertise and thought on the ‘best practice’ approach of configure anti-spam policies in Office 365.
