IS there any limitation of Mail Box size if quota is Unlimited

[sadiq007]

Hi,
I have set Unlimited Malbox quota for all user by setting Account Quota (MB) =0
, apart from this is there any mailbox size limit from zimbra?
one of my user having 15GB of mail in his mail box.

theoretically, no there isn't. i have users with over 30GB of email. but i can tell you the bigger a mailbox gets the slower searches get and at one point i had a mailbox that had a lot of shared email folders and was around 500GB and i had to break it up because people searching it would really bog down the whole server

I am not sharing any folder, apart from search result does bigger mailbox effect mail server performance?

In general, it will not affect the whole server's performance, but like mentioned earlier it might slow down searches for that users mailbox.

However, Zimbra uses Lucene for the indexing technology, which is pretty efficient, so it shouldn't be unbearable.

Other than that, your only limitation is how much disk space you have available to fill up with email.
