 * First of all, thank you so much for this plugin.
    I am aware that currently, 
   the plugin only supports attachments less than 3MB as you answered [here](https://wordpress.org/support/topic/cant-upload-attachments-in-contact-form7/)
   and as documented by Microsoft [here](https://docs.microsoft.com/en-us/graph/api/message-post-attachments?view=graph-rest-1.0&tabs=http).
 * However, I was wondering when would the limit increase, because as per checking
   [here](https://docs.microsoft.com/en-us/graph/outlook-large-attachments?tabs=http),
   it is now possible to attach files up to 150 MB using Microsoft Graph API.
 * Your feedback is highly appreciated. Thank you!

 * Hi, thanks for the query. Whilst 150MB is supported through the API, this requires
   writing code to manage upload sessions which is more complicated. It requires
   some thought on how to implement effectively, especially regarding error handling,
   if the upload fails for whatever reason.
 * The beauty about the 3MB limit is that the entire file can be encapsulated in
   the same data request to the server as the email (i.e. there is just one request
   sent to the API for both the message and the attachment). You don’t need to chop
   up the file into pieces and send them separately to the API, in addition to the
   message, managing each piece’s request to the server and tracking it’s status.
 * As such, whilst it’s something on the list to support, this isn’t planned in 
   the near term.
