Microsoft Word once supported Avery's small Rolodex cards but apparently no longer does. The 5385 Avery Template in Word no longer works under Office 365 (I learned after printing several sheets that never matched up); the advice online was to use the "A4/A5" Avery Templates, not the "Letter" versions. There is no 5385 Template in the A4/A5 category in Word. So I moved to the Avery Website, and downloaded their Word 5385 Template. It downloaded, but came with warnings that it was designed for older versions of Word and probably wouldn't work with newer versions. It didn't!
I know Rolodex is pretty much a dinosaur, but my wife still depends on it. What are the options (short of custom designing a template...)
