I have a Mac Book with Parallels and XP installed. Office 2007 Enterprize. From within the domain I can retrieve exchange mail without a problem. When I attempt to connect remotely utilizing a sonic wall vpn connection I get the above error. I have uninstalled Office, cleaned out the registry then did a fresh install with the same error. I have deleted the ost files and redid connection with the same message. I personally use owa but this user is and exec and refuses. I have searched extensively through the knowledge base here and abroad and tried the fixes that I have found. Any help would be greatly appreciated.

Thanks

Does the vpn connection open? if it does open once it is open can you then ping teh exchange server?

Does anyone else youe VPn to access their mail?

my guess is the firewall block access to yrou exchange server but thats just an educated guess

That is the kicker, once I make the connection to the vpn then start outlook, I get the NTLM login and have to enter in domain username and pw.

I can map to internal shares and open internal webs when connected through the vpn. I have several other members that have no issues, this seems to be a hit and miss.

Oh and yes I can ping the exchange server.

Thanks,

try setting up a vpn profile for th euser using the ip the user can then use the mail appllet in control panel to change profiles although OWA would be much easier!!

I originally created a host file to make it easier for setup, but then after having issues with it, removed host and used IP.

Same results unfortunately.

I have tried the new profile as well, same results. Couldn't agree more regarding OWA, however that is not an option for this user. ie CEO

Also check the following document runs through teh various ports for traffic, if your firewall is blocking the port you are tryingto gethrough then you will struggle, if you go with the http above ensure port 80 is open, if its smtp then you need to ensure 25 is open

I have tried all the above solutions and still no joy. The strange thing that I have found is that when I put in the IP address for the exchange box, then choose the check name. I get the login and have to enter the domain/usernam and pw, I get resolution as it underlines the name. The strange thing is the ip address is changed to the server name when it resloves. I have wiped the hosts file flushed the dns and that info is still being populated. Which leads me to believe that it is in the registry or somewhere in the mac side.

Thanks

if teh name resolves etc and you can connect just not drag down then my feeling is that teh firewall is blocking teh traffic out. i think you shoudl have a look at teh port document i attached above to make sur eyou have the correect port open for the tyup eof traffic you are looking for

are you an administrator and the user isnt it? try making them same level as yourself and trying then... obviously that wont be the answer but will at least pin point wher ethe fault lies.

maybe if your account has admin rights on teh firewall that would be why the traffic is alloowed through

I added a new key to HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook added RPC then created a Dword Value of DefConnectOpts with a value of 0. Now at least when I activate Outlook it opens and shows me the cached info.

Still have not been able to make the connection to mailbox but I consider this progress. I created a dummy account with the same results until I added the Registry entry. I verified connectivity by mapping a drive once connected through the vpn as well as the dummy account name check was successful.

I haven't forgot about this, priorities had to shift. I tried the dummy and no cigar. I am thinking about spending the money and calling Microshaft.

thanks again

The issue is an update with Exchange 2003 and Mac Office. This is preventing it from syncing with the MAC. Microsof thas not yet come out with a patch to resolve this issue.
