Cannot open or save any more documents because there is not enough available memory or disk space when trying to open attachments in Outlook 2016

At times, Word, Excel and PowerPoint files will have some kind or complicated formulas, calculations, or external resources inside the sheets, therefore the security settings in Excel, Word and PowerPoint will prevent opening these files in Outlook 2016.

To resolve the issue, Open Excel, Word and PowerPoint, go to File, Options, Trust Center then click the Trust Center Settings button. Click Protected View and uncheck the 3 boxes that you see there. Click OK.
