Outlook profile changed - spoof?

[John Marsh]

Thanks for the advice. This one's a bit odd. There was only one access event from the 64.4. etc IP address, which occurred a minute after I had signed in. It makes me wonder if someone set up a system to monitor the data pipeline and access accounts when they have just been accessed by their holders.

If it's a snooper, why raise the alarm by changing profile information? I'm thinking it's some kind of quirk within Microsoft.

I have tried to replicate the events of yesterday, by viewing my Profile. No alert e-mails received.
