Accepting an invitation failed with Status 804a000a

Trying different things, I found that I can not create a meeting in my company (Exchange) calendar, or change a meeting in my home calendar to the company calendar - it silently fails. So this may be related. I have not determined if this is an authentication problem or something else.

Can you please capture a debug log and attach it? If the debug output is different, please open a new bug.

Sorry, I didn't get the email. I found the bug again when I did a search :)

I haven't turned actual debug logging on yet (still looking that up) but I found this in the error console when I clicked 'Accept' on a new event invitation (slightly anonymized):

Error: Assert failed: error on iTIP processing

I subscribed to the email, so I should get postings henceforth.

I used this script to start tbird with debug logging (found at http://wiki.dovecot.org/Debugging/Thunderbird)
  #!/bin/sh

  TB_PATH=`which thunderbird`
  # or for MacOSX:
  #TB_PATH="/Applications/Thunderbird.app/Contents/MacOS/thunderbird-bin"

  MYDATE=`date "+%Y%m%d_%H%M%S"`
  NSPR_LOG_MODULES=IMAP:5
  NSPR_LOG_FILE=/tmp/thunderbird_${MYDATE}.log
  export NSPR_LOG_MODULES NSPR_LOG_FILE

  $TB_PATH &
  exit $?

There was nothing in the log that pertained to this, so I tried 'tail -f' on the log, and no new data appeared when I tested this problem. Is there a better way to do the logging?

OK, I changed 'IMAP' to 'all' in the above script, and got some possibly useful data. I have attached it. I tried to reduce the length as much as possible without leaving out anything useful, but of course I don't have any strong idea of what's useful. The result is 403 lines.

Thanks for your effort! That's the wrong debug log however. Please follow the instructions on the wiki: <https://gitorious.org/lightning-exchange-provider/pages/Debugging>. Thanks!

I am having the same problem and followed the wiki's instructions for debug output... Here is what I got

I'm having the same problem. The debug logs are indicating that ReferenceItemID is set to null...

It's sending:
    <m:CreateItem SendMeetingInvitations="SendToNone" MessageDisposition="SendAndSaveCopy">
      <m:Items>
        <t:AcceptItem>
          <t:ReferenceItemId Id="null" ChangeKey="2"/> ...

And getting the following error back:
<m:CreateItemResponseMessage ResponseClass="Error">
          <m:MessageText>Id is malformed.</m:MessageText>
          <m:ResponseCode>ErrorInvalidIdMalformed</m:ResponseCode>
          <m:DescriptiveLinkKey>0</m:DescriptiveLinkKey>
          <m:Items/>

My emails are being read from imap via a proxy - not sure if that could be a problem?

Has a resolution, or cause to this problem been found. I've been experiencing this error code also.

My workaround was to not use the Company calendar at all. I put everything in my personal calendar. I'm still running Lucid and Tbird 7.01 so maybe a newer version fixes this?

Just ran into this, too. In 2017...
