Hi all,

I have a windows small business server 2008 with exchange 2007 on it.
By default I see the mailbox created is in a non unicode-modus.
My client is oultook 2003. Since non unicode can handle only data to a maximum of 2Gb.
I'm getting some errors because my mailbox is over 2gb. So I want to set exchange 2007 to have the mailbox in unicode format. But I don't see how to do this.
I searched some at google. But I haven't found the answer yet.
Please advise me how to do this.

I made a new profile on the client side using unicode. This show that the limit of 2Gb is removed.

New mail from the exchange account is delivered to the new unicode file but then it is not visible in the owa.

I hope someone can help me.

I think you are talking about the PST file of outlook and not exchange mailbox.

In outlook 2003 the PST should be unicode and doesn't have the 2gb limit but rather 20GB

If you have copied the pst from a previous version of outlook than you know why you still have the 2gb limit applied

Create a new PST file.  Select the Outlook 2003 or unicode format.

Then drag all the emails and contacts addresses to the new PST file.

I already made a new .pst file. But then the emails are not on the exchange server. New mails are displayed in the new .pst file. But when I open OWA (outlook web access) I can only see the .pst file wich is not in unicode.

When I make a new .pst file. The owa doesn't display the new .pst file but it displays the old .pst file.
New email comes automatically in the new .pst

But I also want to use OWA so I need owa to display the new .pst

Owa doesn't access PST files, pst files are LOCAL to the computer, in OWA you can only see the emails that are on the server.

If you want your emails to remain on exchange instead of the PST

Tools -> Account settings -> Data files

select the Mailbox - username and set it as default

Hi, I thank you for the help you are trying to give. But it doesn't solve my problem.

By default the sbs server has a user account. The user account makes all the nescesarry settings in exchange so the user has an exchange mailbox. When I go to the client computer. And I'm logged on to the domain. The exchange mailbox wich was automatically created is in the user profile. By default this exchange mailbox is in non-unicode wich makes it limited to 2GB. So, I need to change the non-unicode mailbox to a unicode mailbox on the exchange server.

I tried making a new .pst file on the local client. I can let exchange deliver the mail in the new .pst file. But then the emails are not visible in exchange owa. I really need this feature so I need a way to change the outlook mailbox on exchange 2007 to unicode rather than having a .pst file on the local client wich doesn't display the mail in OWA.

There must be a way to change this. I only don't see how.
Best regards.

i don't know where but I am sure there is a miss understanding between us

if what you are looking for is to make the emails available from OWA then the delivery should be on the exchange mailbox and not on PST

if you want the emails to be available at the same time on OWA and on the local machine then you should go for offline or set outlook to cached mode
