I offer these additional details that might help Microsoft to diagnose the issue:
Initially, in early January, the rules showed completely coordinated and synchronized in my Outlook MS Professional Plus — and also in my Outlook Live account —but performed quite irregularly and the rules
were being applied very incompletely (“hit and miss” … but “missed” most of them).
I could run them from both programs (Outlook in MS Office Professional Plus — and also in my Outlook Live account) but the results were always the same (very incomplete “hit and miss” … but mostly “missed”).
I patiently waited, hoping that the RULES program would eventually “learn” and begin to perform accurately. Instead, after about 10-days (last week) the rules completely vanished from the ‘Rules Window’ in Office Professional Plus and this message appeared
on the bottom of the window: "There are rules created with a different version of Outlook or Outlook Web Access that are not shown.” The statement, however, is incorrect, as the two
programs (Outlook in MS Professional Plus and Outlook Live) have been completely coordinated and synchronized since 2010, with no errors to report.
The rules in OUTLOOK LIVE, however, did not disappear last week (like they had on MS Professional Plus) but continued to exist, as they exist still now. However, like before, the rules continue to perform very incompletely “hit and miss” … mostly “missed”.
Then, AMAZINGLY, this past weekend (25-26 January) THE OUTLOOK LIVE PROGRAM CREATED SIX NEW RULES BY ITSELF (!!) The program also re-organized the 'run-priority' of the 6 new rules, and
each time that I restore my original 'run priorities" it continues to re-organize then again!
Seeing that the 6 new rules are along my same ‘rules-scheme’ (Junk Domains and Social Media) I did not remove the 6 new rules ... they're still there today.
The statement in the blank ‘Rules Window’ of MS Professional Plus was somewhat encouraging by saying that "There ARE RULESCREATEDwith a different version of Outlook or Outlook Web Access****THAT ARE NOT SHOWN” — which also confirms the rules still existing in Outlook Live. So I began using the IMPORT
RULES window and I’ve been doing it all week … to no avail. I also imported DIAGNOSTICS from OUTLOOK OPTIONS>ADVANCED and I tried those with the "rules window" ... but still to no avail.
Strangely, the rules continue to work, but less than about 2% efficiency, and I can't RUN the rules as I did in early January because the 'RUN RULES BUTTONS' in both programs have disappeared completely.
