    AWS S3 MD5 digest with multipart uploads

    AWS S3 MD5 digest with multipart uploads

    In version v2023.1.31.0 we added Verify support for multipart uploads. Some very interesting information can be found here:

    So ..

    1. If an object is created by a Multipart Upload operation, the ETag is not an MD5 digest, regardless of the method of encryption.
    2. For multipart uploads the ETag is the MD5 hexdigest of each part’s MD5 digest concatenated together, followed by the number of parts separated by a dash.

    We added code to recalculate the MD5 hex digest using the Filesize of the download and the ETag ‘stripped number of parts’ we received from the S3 object. This way we could calculate the size and MD5 checksum for each part. This information was used to calculate the MD5 hex digest of the concatenated checksums.

    By default ‘Verify File after Copy / Move’ is enabled which uses the ETag of the S3 object (File) as MD5 hash to compare the download result.

    AWS S3 compatible storage providers

    In version v2023.1.27.0 we made some code changes to make it work with AWS S3 compatible storage providers.

    In the AWS S3 setup select ‘Custom’ as Region. Next set the URL and Region ID of your custom storage provider.

    Trying to connect to a shared mailbox in 365

    Q: I am now trying to connect to a shared mailbox in 365, can you please assist on how I can do this? The authentication is working fine against the user mailbox [A] but I’m not sure how to modify the IMAP4 setup to connect to a shared mailbox.

    Source:  [IMAP4]#adminlimagito@mycompany.co.uk@outlook.office365.com:993

    MailUser:  adminlimagito@mycompany.co.uk

    Shared mail:   health@mycompany.co.uk – mailbox permissions setup, email apps enabled

    I’ve tried using: adminlimagito@mycompany.co.uk\health in the username and various other option all without success [B]

    If I put health@mycompany.co.uk in the Mailbox I think it ignores this and connects to the user mailbox.

    If I follow the instructions https://limagito.com/is-there-a-possibility-to-access-a-shared-office-365-mailbox-with-imap/ it returns error ‘Check Password’ [C]

    Many thanks, Adam

    – Limagito:

    Hello Adam,
    According to our information (confirmed by a user) you should enter the shared mail address as username (health@mycompany.co.uk)
    The reason why in our article the password is left blank is because our user was using OAuth2 authentication.
    ( https://limagito.com/connecting-to-office-365-email-using-imap-and-oauth2-authentication/ )

    That is why you get the ‘Check Password’ Messagebox.

    Question, what happens when you enter health@mycompany.co.uk as username and the password from the admin account (adminlimagito@mycompany.co.uk).

    – Customer:

    As suggested I changed the username to health@mycompany.co.uk

    And left the password is it was for the admin account (adminlimagito@mycompany.co.uk).

    This now lists the health mailbox!

    The source is now: [IMAP4]health#health@mycompany.co.uk@outlook.office365.com:993

    I would not have thought to try exactly that. One for your (&mine) documentation perhaps

    Thanks again for your quick response 😊

    Adam
