"double-quoted string literal" in sqlite.log

Since I was in the log directory due to another issue, I took a peek at sqlite.log.
Line 1:

02/12/2023 11:14:19 28 double-quoted string literal: "Spam filter"

The next appearance of “string literal” is on line 139031:

07/04/2024 06:31:47 28 double-quoted string literal: "MailItems.receivedDate"

with a few more after that until line 139095:

07/04/2024 06:37:15 17 statement aborts at 12: [REPLACE INTO 'contact_data'.'CommentIndex_data'(id, block) VALUES(?,?)] database schema has changed
07/04/2024 06:37:19 28 double-quoted string literal: "MEMBER%"
07/04/2024 06:37:19 28 double-quoted string literal: "MEMBER%"
07/04/2024 06:37:23 28 double-quoted string literal: "MEMBER%"
...

Between July 4 and today, Oct 23, I have found 368121 such lines.

Edit: I have since rebooted, uninstalled and reinstalled, and still get these lines every few seconds:

What’s going on there?

It might be connected to a Teams account. At least the logging stopped after I removed the account from emClient.
