Dear Expert,

My customer just upgrade to Office 2013. but TrendMicro detect when connect internet. it warned "Dangerous". I would like to check, is it dangerous or not. And what's the link objective?

Thank you

Have your updated the TrendMicro to the lastest version?

The clientconfig.microsoftonline-p.net is really a CName which is used by Office 365 to direct authentication to the correct identity platform.

Please contact TrendMicro and put it as their white list.

This is the forum to discuss questions and feedback for Microsoft Office Client, better to post your question to the forum for Office 365 or TrendMicro:
