I have always been under the impression that formulas, even if they are in calculated columns in a table, will not calculate if calculation mode is set to manual. However, after several cases of a workbook freezing on me today, and then testing with a very simple formula in a very small table, it appears that is not the case. Not sure if this has always been the case, but I'm on a very recent upset on Office 365. How can I stop formulas from recalculating in a table when setting calculation mode to manual doesn't work?
