Summary: When encountering a default late flag time issue in Outlook messages, users can adjust the reminder time by following simple steps. This inconvenience often arises from calendar workweek settings. Alternatively, employing the Kernel for Outlook PST Repair tool can address underlying mailbox performance issues caused by corruption, ensuring a seamless experience.

If you’re inundated with a high volume of daily messages and struggle to identify the important ones, consider flagging them. In MS Outlook 2000, you can flag important messages in your inbox for easy recognition. Additionally, for messages requiring follow-up by a specific date, you can set a due date.

At times, when you flag a message for follow-up and set a ‘Due by’ date, you may notice that the default time for the reminder flag is set for 5:00 PM or later. This typically occurs when the time settings for flags are derived from the calendar workweek as configured in the Calendar Options dialog box.

Solution of the problem: To resolve this issue, you can adjust the reminder time in the ‘Due by’ box when setting the flag on the message.

Before changing reminder time, you need to change the calendar work week. To change the calendar work week, follow these simple steps:

  • On the Tools menu, click Options.
  • Select Calendar Options from available options.
  • A dialogue box Calendar Option will appear. Make the changes that you want in the Calendar Options dialog box.

To set a message flag with a specific time:

  • Open the message from your Inbox.
  • Click the Flag for Follow Up button.
  • In the Flag to list, click one of the options.
  • Click the arrow to the right of the Due by box, and then choose a date from the Calendar Control dialog box.
  • Click OK.
