You can address faxes and short messages (SMS) directly out of an Outlook-Contact.
Precondition: The call numbers must have been entered in a valid format.
Please take care with phone numbers, fax numbers and mobile phone numbers that they are saved in an international format:
e.g. +49 8142 47990 not +49 (08142) 47990
Special characters (e.g.: „/", „(„, „)", „-„, „\") should not appear in a telephone number!
Older versions of MS Outlook in some cases offer to bracket or to add 0 to the extension.
