Upon opening Outlook 2003 a window titled 'Microsoft LDAP Directory' pops up. Then I need to click OK before I can use Outlook.

This never used to happan but i have no idea what setting has been changed to cause this.

Any ideas on how i can stop this?

I had this same problem a few weeks ago.  Unfortunately I can't remember how I fixed it, but I think I may have just reinstalled Microsoft Outlook.

Unless anyone has a proper solution, maybe you should that too and see if it works.

For some reason it seems an online directory (form of an address book) has been setup. You could try this.

- On the Tools menu, click E-mail Accounts.
- Under Directory, select View or change existing directories or address books, and then click Next.
- Click the address book you want to delete. (Should be labled as Lightweight Directory Access Protocol [LDAP] account).
- Click Remove.

It's just like removing an e-mail address really. Hope it works!

Thank You Johnny_Mac thats done the job.
