We were getting this error message when we first updated to Excel 2010. A user would select all of the cells in a workbook, try to do something with them (sort, copy/paste, etc), and Excel would crash or give the above error message about available resources. I quickly found and applied a hotfix that addressed the issue, and that was that.
Now we're having the same issue in Excel 2013 (specifically, Office 365 ProPlus click-to-run installation). Only this time, there are not hotfixes available (because it is click-to-run?) and I'm not sure where to go from here. I have a user who is selecting all of the cells in a workbook choosing the option to "Merge and Center", and Excel either freezes at that point or gives the above error message. This is a task he has done daily with these particular workbooks for the last several years without issue, that is until moving to Excel 2013.
Excel was crashing on him regularly after updating to 2013 version, so I replaced his machine with a brand new one and brand new Office installation. He has plenty of memory (machine has 6GB of RAM) and the workbook is not particularly large (a few hundred rows and few dozen columns). I do notice that when the error occurs, the memory in use by excel immediately balloons from 80MB to 1.5GB. However the machine is still using less than 50% of its available 6GB at that point.
I've disabled all add-ins, made sure we're on the latest Excel build (15.0.4517.1005). Not sure what else I can do. Any thoughts?
