Hello,

In Exchange Admin it shows the 'Total Number of Items' in MailBox Resourses, and they show too many (I think).

One user shows over 28,000 items and I have been to look in thier outlook client and there is no way they have that many?

Can anyone tell me what the number represents and how, if possible to get this number reduced.

The Priv.edb is over 1.3 gb in size, is this normal for 50 users?

I have other issues with exchange as well and think I am going to have to re-install it becuause of connecting problems(acording to the error messages I get).

Any help would be great thank you.

Simon

Realize that a mailbox "item" may be an email, a contact, a journal entry, a calender entry, notes tasks, etc.

To reduce the number of items, individual mailboxes will need to be cleaned out. Although you can't limit the number of items in individual mailboxes or as a whole, you can limit the size of individual mailboxes if size is starting to concern you.

There really is no "normal" Priv.edb size for any given number of users. How big this database grows is totally dependent on the email "habits" of individual users.

Realize also that the maximum size for the Private Information Store (priv.edb) is 16GB. If users were storing their info in individual .pst files vs. the Exchange database, .pst files can grow as big as 2GB.At this point I would not get concerned about the size of your priv.edb unless there are other factors involved (i.e. size is growing at a very fast rate or there are backup limitations).

A 1.3 GB priv.edb is not unusual for 50 users.

28,000 items may also not be unusual, especially for a heavy Outlook user. If you are using Outlook, each message in Sent Items, Deleted Items, and Inbox are an item. Each contact is an item. Each task is an item. Each calander entry is an item. Etc. You can view items in Outlook simply by opening a window (Calander for example), and it will list the items in the lower left hand corner.

Also, I don't know if you are running Exchange 5.0, or5.5, but there is no database limit in 5.5. You can check at
