Event ID: 21034 Source: AddressBookService

Level
Description
One or more phone numbers failed to normalize. <value> total numbers failed to normalize.  They are listed in the text file: "\\be-s0253-ms2\lcsabs\Invalid_AD_Phone_Numbers.txt"
Cause: One or more phone number attributes in AD contained text that could not be normalized by the Company_Phone_Number_Normalization_Rules.txt file because the format of the number did not match any of the regular expressions in that file. Resolution: Check the Company_Phone_Number_Normalization_Rules.txt file to make sure it covers all cases found in your AD deployment or fix the invalid phone number(s) in the AD record.
Comments
 
Make sure the file Company_Phone_Number_Normalization_Rules.txt exists and that the normalization definitions are complete and correct. If logged together with EventID 21038 from source Address Book Service, solve that one first.
