System.Net.WebException: The remote server returned an error: (403) Forbidden.

I am using MNE.
Before Oct 2022, I used version 4.15.2.742.
But around the first week of Oct 2022, might be due to the Basic Authunication problem in MS powershell. So, I upgraded MNE to version 4.16.2.74.

Now, i tried the migrate around 10 mailboxs, only two are successfull.
For those which are not successfull. The errors are as below:
"08:24:16 ERROR: [0-239-10-80131509] System.Net.WebException: The remote server returned an error: (403) Forbidden."
"08:24:16 ERROR: [4072-25-4-00000000]Unable to open target mail store 'xxxx@xxxx.com'."

Please help and advise, thanks.

Best Regards,

John Fung
