A digital ID that allows you to sign this message is missing

To solve that problem you will need to do the following:

• First of all get a digital ID
• And then go to the tools menu, and then click Options, and then click the Security tab.
• Next you will need to click Set up security for me on the Exchange Server and then click OK.
• Locate the Digital ID name box and then type your name in there.
• Go to the Token box and then type in the keyword your Exchange Server administrator gave you.
• Next navigate to the Microsoft Outlook Security Password dialog box and there type a password for the digital ID and after you have done that type the password again in the Confirm box.
• You should get a message in the Inbox from your Exchange Server administrator that will need that you provide the password you created earlier.
• A dialog box will appear will click the Remember password for check box and then after that you will provide the number of minutes you want Outlook to remember your password for.
• After all the above is done, go to the Root Certificate Store message that appears and click Yes.

Hi,

Please read the cause of the error for your better understanding.

1.If you do not have the certificate which should be matched to SMTP address

2. Active directory failed to publish certificate

Now, I am going for the solution:

1. Go to run, type mmc and hit enter

2. Click on file and then go to Add/Remove Snap-in

3. Now, Click add and then select certificate

4. Now go to my user account and finish it

5. Now click add computer account and next to finish it

6. Under current user, expand certificates. Right click on the intermediate certificate and go for the all tasks and import those certificates

Thanks for having your time
