Cannot log into hosted sharepoint on Office 365 with IE 9

Today a co-worker found the solution of not able to login into Office 365′ sharepoint.

The solution was simple but effective :

Open IE9, –> tools –> Security –> Trusted Sites –> Sites. Add the following sites :

https://*.sharepoint.com”

https://*.microsoftonline.com”>https://*.microsoftonline.com

Thanks Bob! 🙂
