Reminders support for folders in archives and additional pst-files

I’m storing a couple of my Outlook folders outside of my default mailbox (inside a separate pst-file). When I flag messages in this folder and add a reminder I get the following error;

“The reminder for “<subject>” will not appear because the item is in a folder that doesn’t support reminders. Is this OK?”

How can I add reminder support to this folder?

PST Reminders Support buttonOutlook does support reminders across folders in additional pst-files but by default this option is disabled.

Enabling reminder support for a pst-file is really easy though and can be done in a few clicks.

Enable Reminders Support for pst-file

To enable reminder support for these pst-files;

  1. Right click on the top of the pst-file and choose Properties.

    Outlook Data File context menu

  2. In the Properties dialog enable the option;
    Display reminders and tasks from this folder in the To-Do Bar

    Enable reminders for additional pst-files

  3. You’ll be prompted to restart Outlook. Once restarted, the reminders should work.

    The operation you selected wil not be completed until you restart Outlook.
