  1. Add Secure Messaging to Outlook API

    The current graph API within Outlook doesn't support enabling encryption or secure messaging support. Secure Messaging is becoming the norm for PII and PHI communication and Office 365 supports it out of the box with an E3 license. However, programmatic access isn't available as far as I can tell. Enabling it would accelerate a number of secure messaging initiatives.

  2. Provide message weblink in edit mode

    When POSTing a message using the /me/message endpoint, a webLink is provided in the response. The link point to the draft message in read mode, and the user have to click the edit button to complete and send the message.
    It would be usefull to provide a link that lands directly in edit mode.

  5. Expose 'private', 'confidential' and other sensitivity properties for the Mail endpoint.

    This is quite important for us to determine whether it's appropriate to read an email or not with our tool (currently everything is returned with no indication).

    I'm sure there are many other use cases that require sensitive emails to be identifiable.

  6. Parse the right HTML markup

    When generating an email with Bullet points in Mac Outlook and send the email via Graph the bullet points will become a number if the user opens it on a Windows Outlook Machine. All Outlook products should generate the same markup in Word or HTML. Here is the HTML Graph is returning to the email client which swaps out the bullet points to a number.

    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=us-ascii">

  7. Forward email as attachment using REST API

    Replicate functionality that was available in MAPI/VSTO addins and via EWS to forward email as an attachment similar to the old demo Outlook-Add-in-ForwardEmail, https://github.com/OfficeDev/Outlook-Add-in-ForwardEmail

  8. SharedMailbox members (mailbox permissions) via Graph API

    We are trying to get the members (mailbox permissions) of a SharedMailbox via Graph API. We do not see any Graph endpoint at the moment that can help us get this information. We are in the process of building a custom application where we need to be able to perform read and write operations of SharedMailbox membership/permissions. This functionality is certainly available via the exchange online powershell and I can imagine this being a critical functionality which is not yet available in Graph API. .

  9. Get messages by ids

    In EWS it is possible to get more than 1 mail item by item ids. Can this be supported in Graph API? Graph API seems to allow fetching one message at a time via GET /me/messages/{id}.

  10. Message Copy: Allow to copy message to another mailbox.

    The Current Message Copy functionality is only limited to create a copy of mail under the same mailbox where mail resides.

    This should be expanded to Copy a message from the current mailbox to another user's mailbox

  11. Manage Exchange Admin Roles with Graph or the EWS Api

    I would like to be able to create and manage Admin Roles in Exchange through Graph or the EWS API. This is currently only achievable through Powershell or actually logging on to the Exchange Admin Centre, neither of which are really suitable for my current project.

  12. Deleting multiple messages

    MS Graph appears to only allow single message deletion. EWS allows multiple messages to be deleted soft or permanently (hard deleted). Can this EWS feature be added to the MS Graph?

  15. Make it possible to create organizational Contacts using graph API that appear in Exchange Global Address List (GAL)

    It has been stated by the Office Dev Team that POST organizational contact will not be supported as...

    "With the notion of guests now in Office 365, the decision has been made that Organizational contacts would not be needed moving forward."

    For those of us developing with Exchange-centric customers this causes us to develop solutions that must connect to Exchange Online with accounts that do not have Multi-Factor Authentication enabled. Automation is hindered by having to constantly rotate new passwords (via Import-Clixml) and factor that into the code.

    This is a security nightmare.

    Not to mention, connecting to the…

  16. Microsoft Graph API implement in for $filter query parameters

    https://docs.microsoft.com/en-us/graph/query-parameters#filter-parameter suggests that the "in" directive is supported, however answers from Stack Exchange thread https://stackoverflow.com/questions/64544692/microsoftgraph-api-list-messages-by-specific-categories suggest otherwise.
    Full context. I am looking to retrieve messages containing 1 or more of a list of specific category definitions Where one message has "Yellow" in its collection of categories, a second has "Pink", a third has "Yellow", and "Pink", and a fourth has "Blue", making a request to .../messages?$filter=categories/any(c:c in 'Yellow','Pink') would retrieve messages one, two, three, but not the fourth.

  18. Include message size without needing to use expand=SingleValueExtendedProperties($filter=PropertyId eq 'LONG 0x0E08'),

    It would be great to return the email size directly in the Get Message function, as opposed to having to use Expand to retrieve this field.

  19. Provide Basic Attachment Info in Get Message

    You can see hasAttachments: true|false in Get Message, but having further attachment info (size, name, filetype, hash, etc) would also be useful directly from within the Get Message API.
