I’m running Outlook as part of Microsoft Office Pro Plus 2016 on Windows 10 Version 1909 OS Build 18363.1016. I have several PST files open at the same time, all connected to POP accounts, so there is no Exchange server in the mix.
I noticed a few weeks ago that none of my rules are listed, but they are still functioning. I did not find any solutions online, only some clues, so I started by launching Outlook with the /cleanrules command line switch to start out fresh. After that, I was able to add a rule, but it immediately disappeared from view after closing and reopening “Manage Rules and Alerts”, and did not reappear after closing and opening Outlook.
Next, I started Outlook with /safe , i.e. without extensions, Reading Pane, or toolbar customization, i.e. all add-ins have been disabled. Progress, my rules were now visible, but they would again disappear after adding, editing, deleting, any single rule and closing and reopening the “Manage Rules” form. So in short, while I can tediously manage rules, it’s only one edit at a time, then I have to restart using /safe.
See attached screenshot of hidden rules and temporarily visible ones. One hint maybe the “Apply changes to this folder:” text that’s overlaid the “New Rule”, “Change Rule” etc. menu. If I click on the overlaid text, I can reveal the underlying menu items one at a time, but the rules still remain hidden.
Any pointers are appreciated!
