Hi, I am looking for ETL to add support for application mode oauth support to the software. let me explain, its not the current solution that you provided via the app passwords approach for pop/imap. thats a legacy mode work around that MS allows.
what I am looking for specifically is the ability to download emails and attachments using the following 4 things
1. email address
2. tenantid
3. clientid
4. client secret
items 2, 3,4 are configured and provided by an azure admin ( i can setup a few test accounts for your testing) and a few emails for testing.
the mailboxes can be access via ms graph or ews api, ideally I would like to see get message, save message ( including save attachments), delete message after download, move message to x folder after download - like options both like pop or imap today.
i can also (later provide) the permissions on the azure active directory that are required at a minimum to enable the access to work
I hope you dont come back and say to me - use python scripting and go knock yourself out

i have 2 reasons
1. not everyone will be able to use app passwords on office 365 - in fact app passwords are not available on office 365. live.com is not office 365. Also some companies lock down the user settings in the web/account
2. sooner than later, the traditional pop and imap that you currently support is going to stop working. ( by Q4 22).
