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 happening.
Some accounts can take over a month of tries to be able to have inboxes synchronized.

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.
