Sudden Unable to open Default Folders    
Greetings,

I have recently started having sporadic Exchange 2003 users having issues 
when opening Outlook 2003 to access their mailbox.  They get a message 
similar to:

 "Unable to open your default e-mail folders. The Microsoft Exchange Server 
computer is not available. Either there are network problems or the Microsoft 
Exchange Server computer is down for maintenance."

This problem follows this user from PC to PC regardless of recreating mail 
profiles, etc.  In fact, signing on with full admin rights on the mailbox 
still yields the problem.  This is only 1 user on the affected email server.  
The user is still able to use OWA to access their email.  My only fix thus 
far is to move the mailbox to another Exchange 2003 server which solves the 
problem for the user, but moving the mailbox back to the original server does 
NOT resolve the issue.

I need some help and am really not sure where to look.

Thanks for any and all help.

Sounds like you're having networking issues connecting to that server or  
there is a problem with the server itself.  I'd start by examining the  
Event Viewer on the affected server and look for issues that need to be  
resolved.

Networking issues could range from DNS/Name Resolution issues to actual  
infrastructure problems.

Re: Sudden Unable to open Default Folders    
JonD,

Have you had any luck with this issue. I'm currently experiencing something 
similar. It only affects one user account accessing a particular mailbox. 
Other accounts can access this mailbox just fine, but this one account gets 
the error you're referring to in your original post. 

As you noted, I moved the mailbox to a different store on the same Exchange 
server and this resolved the problem for about 30 minutes.

Re: Sudden Unable to open Default Folders    
Try this fix !! 

start > run > REGEDIT

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
Lsa\[Kerberos]

create new folder called Parameters  
create new dword called MaxTokenSize
value 35535 decimal (should appear as 0000ffff)

Reboot the pc try opening outlook. 

OS: WINDOWS XP PRO
MS OFFICE 2003 PRO (Outook 2003)

Note: Need to be administrator to do this in windows xp pro.

:aaa

Re: Sudden Unable to open Default Folders    
Hello,

We had the same problem.  We fixed it by recreating the local and
roaming user's profile.  This worked after completing the following:

1. Had user log into her peer's workstation and create a new profile -
same error.
2. User can access OWA just fine.
3. Move mailbox to new server - same error.
4. Removed Mailbox Rights and readded them.
5. Created pst, disconnected mailbox, created new mailbox on different
server, reimporting data, new profile - same error.
6. Added test mailbox and assigned her permissions (full control on
mailbox rights and read only on security tab) - same error.
7. Verified RCP_Binding Order.

Thanks,
Exchange2003
