Contacts in Outlook 365
Today we receive a lot of messages. It is nice, if your administrator configured anti-spam rules, but sometimes you need to block some senders. You can block any sender in Outlook in a few steps.
This option controls which address book you see when you open the Address Book (via clicking Ctrl+Shift+B) and when you click the To, Cc, or Bcc buttons when composing e-mails.
With Outlook, you can send a copy of a contact item in vCard format, a standard format for exchanging contact information. This allows the recipient to import the contact data into a contact management program, assuming that the recipient's program supports the vCard standard (as most do).
In Outlook for Microsoft 365 you wouldn't find a distribution list because it's called now Contact Groups, for more details see how to import a Contact Group sent you as an attachment.
In some situation you may want to send your vCard in every message. This lets recipients enter the information in their address book quickly and without errors.
Outlook uses two features to resolve and complete names entered into email messages: AutoComplete and AutoResolution.
vCard, also known as an electronic business card in Outlook, contains contact information similar to paper business cards. You can exchange electronic business cards in vCard format via MMS or instant messaging and send it as an email attachment. If you contact a lot of new people and want them to have your or another person's contact information, you can send your vCard in every email. This lets recipients enter the information in their address book quickly and without errors by importing your electronic business card from the attachment.
