How to migrate from Exchange 2016 to Zimbra OSE 8.8?

Question

Zimbra

Good afternoon! For many days I have been struggling with the problem of migrating from an Exchange 2016 server to Zimbra OSE 8.8. I read the manuals, downloaded the ZCS Migration Wizard and tried this and that. Does not work. The maximum that I managed to do was to transfer the admin box under his own account. No other boxes can be transferred, the error says that there is no access to the box, or the box does not exist at all. Google prompted to share access to user boxes, but this did not help.
Maybe someone faced this problem?

I had a similar problem :(
It was solved like this:
On Exchange, we change all passwords to default (pass123)
on the Zimbra side, we create the same users and with the same passwords (pass123)
(not very nice when there are a lot of users)
In Exchange, in services, start
services. msc -> Tools > Services -> IMAP4 Microsoft Exchange -> Start
On the Zimbra server, install imapsync
apt install git
git clone https://github.com/imapsync/imapsync.git
cd imapsync
make install
the easiest way for 1 user
192.168.10.10 - Exchange
192.168.10.50 - Zimbra

imapsync --nosyncacls --subscribe --syncinternaldates \
--host1 192.168.10.10 --user1 extreme --password1 pass123 --nosslcheck \
--host2 192.168.10.50 --user2 [email protected] --password2 pass123 \
-- regextrans2 's,^(Briefcase|Calendar|Contacts|Emailed Contacts|Notebook|Tasks)(?=/|$), $1 Folder,ig' \
--exclude '(?i)\b(Calendar|Contacts|Emailed Contacts |Notebook \Contacts|Contacts)\b'
