What is an R4 update?
R4 stands for "Release 4", which is how we internally refer to versions of the software running in the service. We release new updates on approximately 9-12 month intervals. R4 came out last fall and our next major update, which we call R5 in the hallways, will be out toward the end of this summer.

Another way to tell if you're on R4 is to click the arrow icon next to the help icon and select "About". In the page that pops up there's a version number, e.g. 14.0.650.25. If the version starts with 14.0.650 your mailbox is running the latest R4 update.
