I have a rather simple question. Is it correct that if I turn of cache mode in Outlook (I am running Outlook as a 365 App against Exchange Online), Outlook rules to not work anymore?
If I try to open Rules and Notifications it says like (it's German) "The requested process cannot be started. An Object was not found"
Once I enable Cache Mode again, everything starts working again? Is there a workaround to get this working with disabled cache mode?
And also, can anyone tell me if rules created while in cache mode, would continue to work, just new ones cannot be created, or will existing ones not even work anymore in Outlook with online mode?
kind regards,
Dieter

Outlook rules should continue to work no matter you are in cached mode or online mode, as rules are stored in the Exchange Online mailbox.
Just to confirm, do the rules actually function correctly for you in cached mode?
Besides creating a new Outlook profile, please also have a check in Outlook on the web to see if you can see the rules there.

See my comment below, I it is reproduceable for me and it looks like either being as designed or a bug.
Existing rules do work correctly whether I am in cached mode or online. just I cannot access them (to add new ones, or modify existing ones) while in online mode from Outlook, just via Outlook Online in that case.
Afaik this should not be the case, if you are able to reliably reproduce this issue, best open a support case and report it. Perhaps try with configuring a new Outlook profile, and set the mailbox in Online mode from the get go?
I got this from a colleague of mine whom we recently switched to online mode because of huge ost file (several shared mailboxes in the profile tec.) And then ii tried it myself,my mailbox is just 2 weeks old, and I absolutely can reproduce this. When I am in cached mode I have me rules and candeal with them. If I am in online mode I cannot access my rules. They sitllw ork, but I cannot access them, to add ones, or modify etc. I can do so in Outlook Online though.
Which version/build of Outlook are you on? I just tested this by creating a new profile and configuring it in Online mode, rules can be accessed just fine. Did you try creating a new profile? Another thing to try is running Outlook in safe mode (hold the CTRL key when launching it, or type 'Outlook /safe' in the run box). Yet another suggestion is to run the SaRA tool and see if it detects something: https://support.microsoft.com/en-us/office/about-the-microsoft-support-and-recovery-assistant-e90bb691-c2a7-4697-a94f-88836856c72f#ID0ED6=Outlook
Can you attach a screenshot of the error you're getting?
Well, if I create a new profile (with the same user) which starts as online from the very beginning, I can access rules menu. If I do switch my cached mode profile ot online it won't work.
My colleague also experienced this problem, that's how we came across it in the first place. However, it's not that important to us now, especially because even in case the problem occurs, that user still can deal with this rules and filters from Outlook Online, the OWA version I mean.
This is quite strange.
What is the affected Outlook version?
You can check it via File>Office Account>About Outlook.
Mine "Microsoft® Outlook® für Microsoft 365 MSO (Version 2306 Build 16.0.16529.20164) 64 Bit". But the one of my colleague might be different. What I know for sure is that she has Windows 10 and I have Windows 11.
Thanks for the information.
It is the exact same version as mine.
While it seems I cannot reproduce this issue in my lab on both Windows 10 and Windows 11.
Please see the following screenshots.
On Windows 11:
Outlook cached mode:
Outlook online mode:
On Windows 10:
Outlook cached mode:
Outlook online mode:
If possible I would suggest contacting support by creating a service request in Microsoft 365 admin center to further troubleshoot this issue.
Thanks for your understanding.
