Hello:

My Outlook.com account rejected an email forwarded to it from a Yahoo account showing the above error message, which I guess relates to Outlook policy.

This was just an ordinary email containing .jpg's  of classic cars from the 50"s, nothing more.

This is the second time this has happened with the last week, but have not had this problem prior to that.

I cannot understand why it was rejected in the first place, but am concerned about it becoming a persistent problem.

Any help on this would be appreciated.

Thanks, Michael
