How to give full mailbox access to imap user mailbox?

Post by Skirk1983 »

Hello,

I have installed Zimbra OSE v. 9.

I have en .NET 4.8 windows service that must fetch emails from Zimbra IMAP email server. The service is connecting to the Zimbra IMAP server over port 993 and I’m connect with my Zimbra admin user. That part works fine.

The windows service must connect to the IMAP server and then fetch mails from other users IMAP mailboxes.

For test purpose I have created normal user and now im trying to give the admin user full access
To the normal users IMAP Inbox meaning all folders.

How to share
The account in Zimbra? Can I give full access to the admin user (or another user if needed). I don’t think normal Zimbra share feature in the webmail is what I’m looking for. But is here another way to give full mailbox access?

Just like in Exchange you can setup
Impersonation or give full mailbox access.


Thank you :)

Hi guy,
You can grant full mailbox access to another user (admin or otherwise) by using the Zimbra CLI tool to modify folder permissions. This can be done via the zmmailbox command, and it allows an admin to access all folders of a target user's mailbox for purposes such as your .NET service fetching emails.

A domain admin with "delegated auth" can access any mailbox (access all messages), both with the webmail (through webadmin) and with IMAP (if the IMAP client is able to use admin-auth).

You could also use "shared mailboxes" (not shared folders).
Have a look at this: https://github.com/Zimbra-Community/sha ... x-toolkit/
