Can not perform this action on your mailbox.

[beauknowsdiddly]

I have an msn.com email address that I've been using for years and years. I always check my email online via outlook.live.com. Whenever I get spam in my inbox I always right click and block. I've been doing that for years as well. A couple days ago, whenever I click block I'm now getting, "Cannot perform this action on your mailbox". I can no longer block emails. Again this is not the outlook from office it's the online version.

I am now experiencing the same problem.

I have the same issue. Sometimes the from address is empty but most of the time my email address is listed in the CC field.
