You try to attach a word document in Sharepoint and error get an Error "Ambiguous name detected: tmp.dde"

Resolution:

·         Research on the above error and found that if we rename normal.dot and reopen the word it will recreate it.

·         Close all the word document and rename NORMAL.DOT

·         You will find that under :

·         C:\Documents and Settings\<your SoeID>\Application Data\Microsoft\Templates

·         Open a blank word document and close it.

·         Check the location again, you will find that normal.dot will be created.

·         Ask the user to open the word document from the Sharepoint site and it should work fine

Found that it is Documented In Microsoft KB articles

 Method 1: Delete the Tmpdde Macro

Method 2: Rename Normal.dot
