Dear list, I may change the smtp addresses of 400 users ;-) Was very happy to found the tool "admodify", since I don`t know how to handle "multi-valued-fields" with vbs (the second proxy address is a multi-valued field) and this tool offers a comfortable way to add and remove smtp addresses from AD users (and many many more BTW). Unfortunately I may have found a bug in the versions 1.4 and 1.5 (don`t know if there are newer versions around, did already a internet research and found nothing): If I add a SMTP-address to one user and enable the option "Gernerate based on current Primary SMTP address suffix" the added address contains only the domain! For example: adding "@mydomain.com" to a user only adds "@mydomain.com" as a secondary proxy-address. There is nothing in front of the @ sign!!! When setting above option and additionally enabling "Set As Primary SMTP address", everything is working fine ;-) Because I do not want to add primary addresses, this is a problem for me and as I think the program does not work as expected here... Anybody heard of this issue with ADMODIFY? Is there a new version which fixes this problem? Any other possibilities or tools to accomplish this task? Greets, Christian
