I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I have checked :

I have check this
-Exchange Remote Connectivity Analyzer and Microsoft Connectivity Analyzer Tool finds no issues
-"Hide name from address list" option is unchecked in ECP
-The Global Address List appears to be fully populated
-In the "Attribute Editor" section of the user account in Active Directory, the "showInAddressBook" attribute looks correct and lists the default global address list
-When setting up the account, go 'Manual Setup' > Microsoft Exchange same issue

ExternalHostname should be your public DNS name (eg.



Get-OutlookProvider | select Name, Server, CertPrincipalName, TTL
Name      Server        CertPrincipalName          TTL

I had a similar problem with nondomain computers. Enabling "ask for user name and password" in security tab (more settings) before asking for verification solved the problem.

open powershell and import-module activedirectory then run

Get-ADUser user1 -Properties msexchdelegatelistbl

user1 is the account name of the user who has the problem, if you find in the result in the 4th line "msexchdelegatelistbl" .... so remove it by running Set-ADUser user1 -Clear msExchDelegateListLink , then try discovering.
