Calendar / IMAP problem with meeting requests

  • One of our colleagues is using his Kopano-Account with Outlook over IMAP. Since a few days he cannot send meeting requests using the calendar. He always gets the followiing error message:

    This meeting is not in the Calendar folder for this account. Responses to this meeting will not be tallied. Do you want to send anyway?

    The meeting is sent and responses come in, but as the message says: the meeting does not track which receipients accepted the meeting request. Any ideas?

    the usual question here would be: what has changed around the time the error first occurred?

    Which version are you running now? Which one back then? Maybe something has changed on the client?

  • It could be that there was an update that time around. It’s a server running the community edition. The version was somewhat older. I think it was “” according to history.log of apt. So we decided to update it and it was updated to

  • Is there any solution for this?

    Hi @s_wolff,

    I did not have any time to further look into it. What would help is if you could try a few older versions (you probably need to compile yourself, since we do not keep archives of nightly downloads) to see if this breaks around a specific version.

    If you’d have a subscription you could also open a support case or have access to our release archive.

    Felix, do you mind, have a look at :
    I do appriciate you insight here.
    I quote “we do not keep archives of nightly downloads”
    The script is making backup as of today also.

    @thctlo yes, I am monitoring github for kopano related repositories and I have already seen your repo popping up. Did not yet have time to pick it apart (but some of the things I saw when you last posted the script here in the forum were already handled, like checking if tools such a curl are present (although I would not install the packages as a fallback and would also not run the script as root, which will then again make your apt commands fail).

  • Hai Felix,
    Yes thats a good suggestion, i could make the adjustment to use sudo in the script.
    I’ll have a look a that part again.
    Thanks for the reply!

    use sudo in the script

    I would recommend otherwise. Just don’t install packages automatically, but give clear error messages to users that they need to install “tool x” to run the script.
