I have OE 5.0 (rather old, I know) and got error \“Make sure that your disk is not full or that you are not out of memory. Contact Microsoft support for further assistance (0x80040154,2).
I tried resolving by reinstalling Msident.dll file and the Msidntld.dll file, but it did not solve problem. Replacing msoe.dll, nor reinstalling IE did solve.
Only reinstalling Windows (98) solved it !!!!
