I have made some tests and I shared that zimbra_imap_folder_pagination_enabled option in our Telegram Zimbra group so other could test it too.
We all gt the same results: u nfortunately it doesn't changed nothing.
One of my colegues in the group said he felt "some" improvement in mailboxes with 10Gb or less, but not much.
FTR we all increased the time between send/receive cycles in Outlook too.
I was so hopeful that could fix the issue but it seems that's not the case.
Any other suggestions or tests we could perform?

>> Welcome to the Zeta Alliance. The issue you have described has some similarities
>> to a known issue that can occur with IMAP and large mailboxes, where an IMAP
>> sync never completes. This can also affect outbound email too, if the inbound
>> email sync never finishes. Back in 8.8.15 Patch 15, two new settings were
>> introduced that may help: zimbra_imap_folder_pagination_enabled and
>> zimbra_imap_folder_pagination_size ( [

>> Hello All,
>> This is my first message to the list =)
>> Nice to meet you.
>> I'm from Brazil and I have been working with Zimbra OSE for more than 10 years
>> now. I'm a huge fan.
>> As you asked I'll like to talk about IMAP issues we have been facing since
>> version 8.8.15 when using Oultoook e-mail clients.
>> There is some sort of delay when Outlook is used. Let me give you specifics:
>> 1 - Mailboxes never sync, no matter it size. Bigger mailboxes tend to be worse.
>> No matter what we do: index, redo setup, change Outllok version... it just keeps
>> synchronizing forever.
>> We can see messages of UID FETCH in mailbox.log but it's like nothing was really
>> Some accounts can take over a month of tries to be able to have inboxes
>> 2 - With all set, a message can take up to 10 minutes to reach Zimbra. Crazy
>> stuff: the message sit in outbox for 5 to 10 minutes before it makes the first
>> HELO with Zimbra.
>> 3 - Same with arrival, but it's worse sending.
>> Extra information related to this:
>> 1 - If I install and configure Thundrbird in the same computer, using the very
>> same account, sync and sending issues just don't happen. "magically" it works
>> fast and as expected with Thunderbird but not with Outlook;
>> 2 - We have this quite big Telegram group oriented to Zimbra in Brazil-
>> @zimbrasil - and I was told by friends there that Zimbra 9 NE doesn't present
>> that issue. But all Zimbra OSE admins are complaining about it. You're welcome
>> to join us and listen to them.
>> This has become a serious issue.
>> 3- I have a topic open about it in Zimbra forum for a quite long time now with
>> no comments =(
>> I would really appreciate if you can give us - Zimbra OSE admins - some
>> attention on that matter.
>> Thanks for your attentions and I'm sorry if my message is too long.
>> Please don't hesitate to ask me anything.
