Users of Microsoft email services are well acquainted with the OST format, which is used to store data in encrypted form. Converting OST files allows you to get rid of format restrictions, after which mailings will become available to the user for offline work in Outlook.

Microsoft Outlook uses the semicolon as a separator between addresses. However, a natural way to type multiple addresses into the To, Cc, or Bcc fields is to use commas. If you are used to commas, you can customize Outlook to recognize commas as separators.

If you need to send a copy of the email to the recipient that should not be visible to other recipients, you can add her/his address to Bcc (blind carbon copy). Addresses in the Bcc field are not visible to the recipients in the To and Cc fields, and each other.

Exchange Server users can share a contact folder with another person inside and outside of the organization if sharing contact lists is supported by the organization's sharing policies. If you do not have an Exchange Server account or your organization policies do not allow contact folders sharing, Microsoft Outlook does not offer the Share Contacts option. However, you can share contact lists, email groups, or distribution lists by creating the contact group, attaching it to the email, sending the email, and importing.

If you regularly send emails to the group of people like your project team or your amateur soccer club, a one-time effort to create an email group for the distribution list pays off in the future many times. Microsoft Outlook offers a Contact Group to manage contact lists with a handful of personal contacts, email groups with dozens of team members, or distribution lists with thousands of subscribers.

A lot of people prefer to see the Calendar with busy times on the paper or share their availability schedule with others without sending Outlook calendars. Microsoft Outlook offers the way how to save as pdf file or print the calendar events in another useful form.

The AutoComplete list is updated automatically after sending an email (see more about AutoComplete feature). To make it easier to work in Outlook, you can add useful email addresses to your AutoComplete list without sending emails.

By default, Outlook uses the AutoComplete list to suggest email addresses. If the AutoComplete feature is not disabled in Outlook (see how to turn it off), the AutoComplete list is updated automatically after sending an email. From time to time, people make mistakes when entering addresses or receive incorrect addresses for use.

The AutoComplete feature generates an AutoComplete list, also known as the nickname cache. This list is generated automatically after sending email messages from Outlook:

The standard Outlook work weekdays are Monday-Friday, and work hours are 8:00 AM - 5:00 PM. The Scheduling Assistant uses this information to show your availability when someone wants to schedule a meeting with you. Skype for Business can forward your phone calls to an alternate phone using this information.
