Zimbra Forums

Hi all,

I am trying to sync a user's mailbox that is over 76GB in size. I have tried to modify the size limits for .pst files on the computer (reference https://support.microsoft.com/en-us/help/832925/how-to-configure-the-size-limit-for-both-pst-and-ost-files-in-outlook), however I was unable to set a registry DWORD entry to 80GB (85,899,345,920‬).

Is there a better way to set these values or any other tips for large mailboxes with the Zimbra connector?

Thanks!

The settings for adjusting the pst file size can be found in the section Miscellaneous-> PST Settings. The following 2 settings need to be modified;
Large PST: Absolute maximum size
Don’t set this higher than 4294967295
Large PST: Size to disable adding new content
Don’t set this higher than 4090445042
If this doesn't help I would recommend you connect with Zimbra tech-consultant. He can help you with an exact solution.

Thanks Lewis!

Can I find those settings in Outlook or in the WebAdmin Browser console?
