How do you access custom Follow-Up flag values ("Flag to...") in Outlook 2016?

I'm trying to work out how to access this custom Follow-up flag text in a list view, but cannot seem to find what I need in the available display fields.

Here's what I'm doing to flag a message to read later...

1. Add a custom flag

2. Populate "Flag to" text

3. Mail now showing as flagged

4. The Tasks list only shows basic flag status information

I would like to access the "Flag to" field for filtering/grouping purposes, but I cannot find it in the field chooser menu...

Is it possible to access this value to create views? If so, how?

Many thanks, James

Yes, this is possible. The field is called Follow Up Flag

Right click on Search Folder and select New Search Folder...

In Advanced tab > All Mail fields > Follow Up Flag:

Condition dropdown should be is not empty

Click OK

Now, you just need to Group By the field Follow Up Flag

You can see in my screenshot, I have four different groups. The default is Follow Up, but as you know, you can have other Follow Up flags.

One caveat: The Follow Up Flag is tied to the individual e-mails and not part of Tasks. This means that your Tasks, even if flagged, will not appear in this custom search.
