Happen to have a calendar that is email enabled on SharePoint but calendar items aren’t being created from an email?

Check your ULS logs on your SharePoint server that and see if you have something similar to this error below:

An error occurred while processing the incoming e-mail file C:\Inetpub\mailroot\Drop\86d3c93401cab0ba0000002b.eml. The error was: Value cannot be null.  Parameter name: stream.    

This is most likely related to using an Exchange contact that forwards to your SharePoint calendars email address. Change Use MAPI rich text format to Never.

    And what if this does not help?

    I have several lists on SharePoint web and in lists based on Announcements template are incoming emails OK, but in list based on Calendar template it throws this error…

    I have already tried several things including adding Announcement content type into this list, but it doesnt help as well. And we have Use MAPI rich text format to Never, of course…

    Any suggestions?

    Thanks in advance.

    Best regards #JK

      Got it!

      Calendar lists are not intended to receive normal text emails, but meeting invitations! When I send an meeting invitation into my calendar list, it works…
