Recommendation for big mailboxes

If you are using Outlook and your mailbox is quite big (>15 GB), it may happen that your local ZDB-file (a file where the mails and indicates etc.. are saved) try to become more that 50 GB which is not possible within the Microsoft Outlook Policy. So it won't work anymore.

That's why we recommend to

  1. Clean up your mailbox from time to time, delete old mails nad the trash
  2. Compact the Zmbra ZDB file


Here is how it works:

Open Outlook -> File-> Account settings -> Data Files -> Double-Klick on YOUR Zimbra account -> ZDB Configuration -> Compact ZDB
