[Exchange-Online][EWS] FindAppointments method on public folder calendar error. returns folderID not ItemId is the message

    Question

  • Looking for confirmation. Seems like there is a bug in ews for O365

    Since earlier today there is a problem with the FindItemresults / FindAppointments method when used against a public folder calendar.

    Seen this with 2 different office 365 users on different domains.

    Can anyone confirm?


    Thanks, John

  • I am seeing similar in a script with EWS and O365 - just started in the last 4 days (script runs twice a week).  My error is Exception calling "FindItems" with "2 argument(s).  My searches were not helping until i found this post.  my concern is that the Exchange version is now 5.20.x.x - all i can find on it is that it may be version 2019.  I don't know if they recently updated exchange and introduced this issue.

  • Have a look at this:

    I am working on changing my script with Contacts based on this to see if it works.
