Office 365 multi-factor authentication with Google Authenticator

I recently learned that it’s possible to use Google Authenticator (or any other authenticator app) with Office 365 for 2-step verification. That’s great as I’ve always believed it was Microsoft Authenticator or the highway. I’m sure Microsoft Authenticator works fine, but I don’t want multiple authenticator apps on my phone.

Submitting abuse reports to Microsoft might be a waste of time

About one and a half months ago I experienced a lot of botnet traffic originating from major cloud providers including Microsoft Azure. Against my better judgment I decided to see if reporting a few bad IP’s to the MS CERT team would make a difference.

For the last few days, an increasing number of Pidgin-sipe users have been rejected while trying to connect to their Office 365 accounts.
According to the SIPE developers, Lync servers (Office 365) have started rejecting the RC4 stream cipher. Even though it breaks the SIPE plugin, this could be seen as an improvement as Microsoft has recommended to retire RC4 as used in their TLS implementations for years.
