Newbie here. I have an iMac, came with Lion. running 10.7.5. I'm running Microsoft Office for Mac 2011. I worked on an Excel file for a couple days, saving and closing. On the second day I opened the file, worked, saved, finished my work, then saved/closed. When I went to open today the file was not in the "Recent" list and I cannot find the most recent version. I checked the trash, it was not there. There is a very old version of the file with the same name but not the updated file. Any ideas about what happened to the updated file? No software updates since I started working on the file. Autosave was and is set to every 10 minutes.
Thank you for your help.
