Excel not enough available memory or disk space available

Excel can sometimes throw to following error to you:

Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space.

  • To make more memory available, close workbooks or programs you no longer need.
  • To free disk space, delete files you no longer need from the disk you are saving to.

    Weird thing is that it doesn’t matter how fast your Computer / Notebook is. We did recently upgrade our machines to Core i5 / 8GB Memory and some users still get this error message. Below instructions does fix this in most circumstances:

    1. Go to Run -> dcomcnfg (for 64 bit: dcomcnfg -32)
    2. Click Component Services -> Computers -> My Computer -> DCOM Config
    3. Right-click on “Microsoft Excel Application” and select “Properties
    4. On the “Identity” tab select “The interactive user.
    5. Click “Apply” to save the settings. Restart Microsoft Excel and the issue is resolved

    Notes: Some people advice to also give “” Read/Write permissions. You can do this on the “Security” tab. In my case this was not needed in order to fix the issue.

      The solution is easy – it’s just a stupid error message that has nothing to do with the actual problem, and the problem is actually a microsoft feature, as often is:
      – Office now has some kind of “protected-mode” feature, which prevents office apps from doing certain things under certain conditions.
      – One of them is to stop excel from opening attachments coming from outlook 🙁

      Just go in Excel options, trust center, settings, and untick all the options about “protected view”.

      Save and voila, suddenly excel can open all your files and has absolutely no problems with your gigs of free memory.

      I am using Office 2016 on Win 10 and I am receiving this “not enough available memory…’ error. This is what worked for me:

      Right-mouse clicked on Word or Excel file; selected Properties.

      Under the General tab, at the bottom there is a section titled “Security:”

      It states “This file came from another computer and might be blocked to help protect this computer.”

      I checked off “Unblock” and I was able to open the file.
