If your data files in Outlook won't open, or items appear to be missing in your inbox, then your PST file is probably corrupted. However, there is a way to recover your emails, contacts, calendars, notes, etc.
There are several Outlook startup switches. The most common switches are listed in this tip.
AutoArchive in Outlook moves old items to an archive. You can customize it for more comfortable using of Outlook.
By default, Outlook, displaying the note, shows the date and time of the last modification that was made to the note, but you can hide those time stamp.
Having notes of different colors can help you be more organized, and sometimes different-colored notes will help put a smile on your face.
Outlook, like other Office applications, supports AutoCorrect - a feature that allows Outlook to correct common spelling and typing errors and to replace characters with symbols. You also can use AutoCorrect as a shortcut, which means you can type a small string of characters and have those characters replaced by a longer string.
Outlook can display either the number of unread e-mails or the total number of e-mails in a folder alongside the folder name.
This rule will be useful if you receive a lot of messages (for example, reports) from your colleagues and use rules to copy or move correspondence to the specific folders (like Rule to copy all correspondence about some subject to the specific folder or Rule to move all correspondence about some subject to the specific folder). Unfortunately those rules wouldn't work for messages with empty subject, but you still can create a rule to send an Auto-Reply if the message don't have a subject.
If you want to construct a more complicated distribution list, with some recipients on the To field, some recipients on the CC field, and yet more recipients on the BCC field, you have to use a message template where you explicitly assign recipients to each field.
Any of Outlook's default views can be modified to suit your needs. You can customize the fields displayed, sorting, grouping, filtering, fonts, and other formatting options.
