Hi All,

sorry for my english...

last week we made a bulk update on Active directory, and after that some users reported to us that the Outlook Personal Contacts  has modified, the mobile field where they have phone numbers was overwrite with the AD value.

We made this kind of Active directory update every 6 months,  why our phone numbers has been modified only this time and not the previously updates?

Should be an Outlook Update?
Thank You
Michele
