There are two issues that affect the display of Outlook's calendar at the beginning and the end of the month. This is the result of the limitation in the number of weeks Outlook displays on screen and the use of the compressed weekends.
There are fewer display issues with Outlook 2007 and Outlook 2010's calendars, in part because compressed weekends are not an option.
Today's Date is not Selected: Outlook displays the end of last month instead
When either of the following conditions are true and the month begins on a Saturday or Sunday, and ends Monday or Tuesday (causing the month to span 6 Outlook calendar weeks), it appears that the last Monday of the previous month is selected as "Today".
- You use the default setting of "First Day of Week: Sunday" and the default of Compress Weekend days enabled.
- You use "First Day of Week: Monday".
The screenshot on the left shows the week beginning on Monday. The one on the right uses compressed weekends.
***Note that while these settings are the default or most common, other First Day of Week: settings may have the same affect, depending where the first day of the month falls.
This happens because Outlook displays only 5 weeks at a time and it always displays the week containing the first day of the month at the top of the screen. The first day shown on the calendar (which happens to be the last Monday of the last month) is selected because 'today' is off the screen.
- Change the first Day of Week or Compress Weekend settings so the month spans only 5 weeks.
- Press the Today button or right click on the calendar and choose Today.
- Wait a couple of days for the first of the next month to correct it.
To change your default First Day of Week setting, Tools, Options, Calendar button.
To change the compressed weekend settings, right click on the calendar and choose Other Settings.
Outlook's Day/Week/Month calendar begins with last month.
Outlook's Day/Week/Month calendar begins with last month. This is because Outlook always displays full weeks and begins the month with the first day of the week that contains a day in the current month.
Outlook does not offer a setting to display only the week containing "Today" and the next 4 weeks.
This screenshot shows May 2005. Because the weekends are compressed, the calendar begins the week on Monday while Saturday and Sunday share the last square. Since the first day of the month is in the last square of the top row, the calendar starts at the end of the previous month.
When the compressed weekends option is enabled and the month covers 6 weekly grids, you won't see any days that extend past the fifth Sunday and Outlook selects the first day of last month as "Today". This is because Outlook only displays 5 weeks at a time and any month that begins on a Saturday or Sunday and ends on a Monday or Tuesday is stretched into 6 weeks when you use compressed weekends.
Because Outlook displays the full week that contains the first day of the month, disabling Compressed Weekends will correct the view problem. To disable it, right click on the calendar and choose Other Settings. Remove the check from Compress Weekend days.
