Export email details from Outlook to Excel

Question

I have a code (which I copied and edited it slightly from How do you extract email addresses from the 'To' field in outlook? and another source which disappeared) that is currently functioning to extract the dates, and names & email addresses (Sender, Recipients, CC) of every email in a specific mail folder. However, after cross-referencing with the manually exported email list from Outlook (via the Import & Export Wizard), I realized that there were about 30 emails which had an error in the VBA exported table. For each of these rows which contained information from their respective email, the names in the "Sender", "To", and "CC" were blank, while the corresponding email columns were just a copy of the previous email which was successfully extracted. So far, from what I observed, the similarity between these emails is that they are for Microsoft Team meetings (e.g., invitation to attend a teams meeting). The image below depicts the error:

Furthermore, one individual had two email addresses (each with different domains). However, only one of the email address was successfully exported out for its corresponding email; the emails which contained the other email address failed to export that particular email address, even though their name was still there. Similarly, the error was like this:

Kindly help me to identify and if possible, rectify the above problems as I have little to no experience in coding. Thanks in advance. The code is as follows -

Error handling can be tedious which is why the blanket On Error Resume Next is often seen. This hides errors so results are not trustworthy. It is baffling to the inexperienced as "the code runs".

Arguably On Error GoTo ExitFunction is better as it gives no results so you are made aware there is a problem.

With both On Error Resume Next and On Error GoTo ExitFunction removed you can build your own error handling logic once you see where error handling is required.

Adjust as you see fit.
