Filtering on Outlook node does not work when multiple folders are selected

[CMLabay]

Bug Description

When using the Outlook - Message - Get Many node, there is bug related to filtering on multiple email folders.
When only one folder is selected, the filtering works as expected.
However, when multiple folders are selected, all messages are retrieved (up to the limit).

The images below, show a filter query on 'categories', and then Folders To Include is set to include two folders, and one folder, respectively.

Expected Result:
Only messages in the specified category are returned when more than one folder is included.

Actual Result
When more than one folder is included, messages from any category are retrieved.

With multiple folders

With a single folder

To Reproduce

1. Add an Outlook node and connect a credential
2. Select the resource - Message
3. Select the operation - Get Many
4. Click - Add Filters button
5. Click the Add Filter dropdown, and select Filter Query
6. add a category filter - categories/any(c: c eq 'your category')
7. Click the Add Filter dropdown, and select Folders To Include
8. add Inbox, and Archive folders
9. Click Execute Step

Expected behavior

Only messages that have the category 'your category' should be retrieved from both the Inbox and Archive folders.

Filtering on Outlook node does not work when multiple folders are selected

---

Reproduction: Docker, Self-Host, Debian, Version: Next(1.121.0)

Applied an any filter with c:c equals 'Blue category' toGet many messages Microsoft Outlook node version 2 (Latest). Chosen folders: Inbox. Node output contains only matching categories inside Inbox folder as expected.

Added another folder Sent Items and executed node with the same filter query. Node has returned all items inside the specified folders disregarding the filter query altogether.
