In Outlook 2016, I can't open Signatures or Stationery and Fonts or other options from Outlook Options. I click on the buttons and Outlook freezes for a few seconds then doesn't do anything.
Only error is when I close Outlook there is a dialog box that says outlook has insufficient memory do you want to save normalemail as a rescued template.
Tried this with a different Office 2016 install, repair of the install, uninstall and reinstall of Office 2016.
Same problem in Outlook safe mode and I can't disable add-ins to test that as the dialog box doesn't open.
