If Outlook PC is asleep at night, should it apply Client-Only Rules when it wakes up and downloads messages?
I have some Client-Only rules for assigning categories to certain inbound messages. Obviously, they can't run when PC is offline due to sleep, but I expected that they would run when the PC wakes up and downloads them (in the past, we had PC's on all the time with Outlook always running, so this wasn't an issue until recently as we've worked to reduce electricity usage). If users manually run the rules on everything in the Inbox, they work perfectly every time.
My understanding was that even if Outlook is offline when the messages reach the Exchange Server (as part of Microsoft 365), that when they are downloaded to Outlook for the first time, Client-Only rules will be applied then. Is that incorrect? What is the logic for how/when Client-Only rules will be applied?
If that is correct, then any idea why rules fail to run and assign categories automatically, but always work when I run them manually?
Also curious why assigning a category is considered Client-Only. Any reason the Exchange Server can't do that? Categories are stored on the server, so Exchange has all the information it needs to be able to run these rules. If you agree that these should be able to run on the server and avoid all the problems with Client-Only rules (especially as MS plans to move people to the New Outlook, which will still get all the benefit of Server rules doesn't support Client-Only rules), please upvote my feedback on this at: https://aka.ms/AAn3uus
