Windows 7: Outlook 2007 telephone numbers appearance

I am trying to add telephone numbers in contacts and for some reason every time I start a number with +123 it would automatically erase + and leave only the 123 and this form is not valid when trying to make a phone call. I would really appreciate someone helping me with this.. Thanks in advance

Using Outlook 2010 I have no problems saving phone numbers with + and country code (+1 for USA & Canada, +49 for Germany and so on). As far as I can remember Outlook 2007 it also accepted + and country code in contacts?

If not, then simply use 00 instead of +. Both work as prefix to country code so a phone number can be told and dialed using both, for instance +1 202 456 1414 or 001 202 456 1414 for a certain residence in Washington, D.C, and +49 30 2000 2021 or 0049 30 2000 2021 for respective residence in Berlin.

The thing is I am sure it's possible to enter + if you set parameters somewhere, but I can't find where. I know you can do it with 00 also, but still I would like to know how to set it with +. Thanks Kari for the reply
