Outlook cache mode and hybrid Exchange problem
Hi Christopher,
Thank you for your answer, but I don't think that's how cache is working. We use cache for other customers and the behavior is that Outlook store recent mails (depends of the cache duration) in local so even without internet, mails are available and if the user want older mail then with a search he can retrieve what he want in Outlook.
And in the fact, it was working last week, I think before the fresh install of the Exchange 2016.
Do you have another idea ?
Thank you
Hello,
Thank you for you answer, from my point of view and I think I'm not the only one, if what you said is right, it's a really bad choice from Microsoft. Do you have any official documentation that explain the cached mode with Exchange Online ?
What I don't get is that on another account from another O365 tenant, the cached mode works well. I have 1 year of local e-mail and I can search on the server from Outlook without any problems.
It seems really strange to me.
Thanks
Now that I think about it, I'm betting because Online Archives have been turned on, the whole new "Sync shared mailboxes offline" is causing this issue possibly, and applying to your main folder as well. Worth a shot. Check out method 2 in this article.

Turn that off and see if it affects the primary mailbox as well.
But even in this article: https://support.microsoft.com/en-us/help/2733062/only-a-subset-of-your-exchange-mailbox-items-are-synchronized-in-outlothat lead me to that it says if it's configured to anything other than all, your only going to see the offline items, your supposed to get a "Search items on server link thou". Which I know in the past I've had that issue where it doesn't show that either but right now it seems to be working normal again. I'll have to ask the support guys at work. But if you want to try that option above and see if it doesn't anything for you.
Hello,
After some tests, I still didn't find the root cause of the problem but I have more information about the problem.
- Not all users are impacted by this problem, for some users all search are totally ok.
- And for others users sometimes there is the problem and sometimes not.
When the problem occur, the search retruns always 75 items and then outlook prompt "Searching" but no other results will appear. Even if there is only cached items in the 75 results.
But I still don't find the problem, any others ideas ?
Thank you
