Describe the bug

I am attempting to share a document file with a user using the invitation method CreateSharingInviteAsync.

I executed the code as shown below, and it ran without any errors. I also verified that the document has granted read permissions to the user. However, the user did not receive the invitation email, despite setting SendInvitation= True.

here is my application permission

here is my sharing settings

Expected behavior

An invitation email should sent out to the user

@ZiLin3 : I've just tested this myself by making the Graph call outside of PnP Core SDK (https://learn.microsoft.com/en-us/graph/api/driveitem-invite?view=graph-rest-1.0&tabs=http) and I'm also not seeing a mail arriving. There's however an Exchange incident reported for my test tenant, that might impact this. Can you cross check that if you make the actual graph AAPI call things work for you?

We're experiencing the same issue as @ZiLin3. Our code that uses PnP to share succeeds but no mails are sent out.

@jansenbe - I tried calling the Graph API directly and it also succeeds. But no mails are sent.

I tested using Graph API, it succeeds, but no receive any invitation. Result same as @nel0 .

@nel0 / @ZiLin3 : this is a platform issue. I would recommend that you (or your customers) open a support ticket explaining that the Graph call (show the raw API call not working from Graph Explorer or PostMan) is not triggering mail sending. From the PnP Core SDK side there's not much we can do, this feature used to work previously, so clearly something changed at the platform side.
