Why is my phone asking me to encrypt my SD card

[AC Question]

the last couple of days I have received a message that my SD card must be encrypted before I can use it?
says I cant skip as it was requested by an administrator?

Welcome to Android Central! Which phone? Is the phone encrypted? Is it a business phone? If you use the phone for business, and your company has required some kind of security policy, it might be requiring any SD card that you insert to be encrypted as well.
