preparing for final migration

[browland]

I am looking for an easy way to clear all email from every mailbox on zimbra prior to final migration. I have a script to delete all accounts and one to create them all (370 in all) however do not want to lose the shared folders and calendars during this cleaning process. Is there a way or command which will enable me to complete this task?

I am looking for an easy way to clear all email from every mailbox on zimbra prior to final migration. I have a script to delete all accounts and one to create them all (370 in all) however do not want to lose the shared folders and calendars during this cleaning process. Is there a way or command which will enable me to complete this task?

I would go with my first suggestion (A), but here's several methods:

A) In the Admin Console GUI> COS (or individual user) > advanced tab > scroll to the bottom > and you can set:
Email message lifetime -Number of days a message can remain in any folder before it is automatically purged.
The default is 0; email messages are not deleted.
Set this to 1 & all the mail will be gone after one day. Don't forget to set this back!

Via command line interface that would be:
su - zimbra

COS ('default' etc)-
Check by:
zmprov gc COSname | grep zimbraMailMessageLifetime
Set by:
zmprov mc COSName zimbraMailMessageLifetime 1d

OR User Level (but COS will be much faster for your purposes)-
Check by:
zmprov ga user@domain.com | grep Lifetime
Set by:
zmprov ma user@domain.com zimbraMailMessageLifetime 1d


B) There's also the emptyFolder command. But if they have /Folders at the root level it doesn't help you at all because you'd have to spend time doing a 'getAllFolders' first and you "do not want to lose the shared folders and calendars during this cleaning process" (ie you don't want to empty /Calendar etc).

zmmailbox -z -m user@domain.com emptyFolder /Inbox

OR

zmmailbox -a admin -p password -m user@domain.com emptyFolder /Inbox

OR

zmmailbox
mbox> adminAuthenticate -u https://server.domain.com:7071 admin@domain.com password
mbox> selectMailbox user@domain.com
mbox user@domain.com> emptyFolder /Inbox


C) Trash everything then set the zimbraMailTrashLifetime low

zimbraMailMessageLifetime: 0
zimbraMailSpamLifetime: 30d
zimbraMailTrashLifetime: 30d
zimbraPrefInboxReadLifetime: 0
zimbraPrefInboxUnreadLifetime: 0
zimbraPrefJunkLifetime: 0
zimbraPrefSentLifetime: 0
