The Queensland government says a $26.5 million messaging and email deal with Microsoft will save taxpayers money.

The Queensland government has struck a $26.5 million computer deal with Microsoft.

Under the three-year agreement, 149,000 public servants will use Microsoft’s Office 365 software for messaging and email, and the enterprise social network Yammer.

“This new contract means that for the first time all government departments will have access to the same technologies,” Information Technology Minister Ian Walker said in a statement on Thursday.

The whole-of-government contract provides the flexibility to move between computer and cloud-based software and is expected to save taxpayers $13.7 million.
