Exchnage Server 5.5

Try to reinstall Outlook (reinstall MS Office) on the client machines. I've seen reference to this resolution for a similar problem.

1. Could be a password synchronization problem. Have one user change their password. (They can change it to the same thing if they want). Wait for replication to occur and try again.

2. Could be an Outlook profile problem. Create a new profile for one user and see what happens.

There's a setting on Outlook Services.
Tools>Services>Exchange Server Service >Advanced Tab.

This should be set for NT password auth.
It should NOT be set to none

I'm confused.

You say that they are being prompted for a u/d/p when they open up outlook w/exch right?

Well, if they are logging into win with a different u/p then their domain password then they will be prompted with that box.

Regardless of the settings in the outlook client.

If the authen level is set to none, that means outlook will rely on the credentials being supplied by the OS. If they are different then what exchange wants (which is the domain u/p from the domain the exchange server lives in or trusts), then it will prompt for a valid u/p.

They need to put in the valid username/domain/password.

All 3 fields need to be filled in.

*OR*

They need to log in to their machines with a domain account, into the domain, not the local machine. And set your outlook auth to none (poster 3)

All of these things are good concerns, but do not work. I tried to install isa server last week on the same box, and it did not go over too well, so I had to reinstall exchange. It worked great for 2 days, and now I am getting this error. All configuration has stayed the same on the workstations, and there were some error messages in the event log associated with dcom service that had to do with mdm.exe on the server. This server also cannot be seen through server manager on any other server (2000 box, NT 4.0 domain). I get an access denied error. This tells me it is probably not workstation conig or an exchange error at all. I can view shares and mapped directories.

This could be the result of not installing and configuring Active Directory Connector a.k.a "ADC"
Try to configure ADC either bothe direction or one direction as you would like the directory synchronization to take place, so both Exchange Server 5.5 Directory and Active Directory can synchronize the account database correctly. After the directories synchronized you should be able to get rid of the problem you having.
All the Best.

I finally backed up all of the exchange data and did a reistall of the operating system. This was not a painful as I though it would be. I did not do an export of the databases (mistake) but all files were able to be restored by running the isinteg.exe file after replacing the mdbdata folders back in their original location. For anyone who has to do this task, the q base article is q162353. Thank you for all of your input and help.
