Additional Information

There is no solution yet. If I reset the calendar cache, Thunderbird closes and restarts and reloads all calendar data without errors, but on next restart, the same error occurs again.

TagsNo tags attached.

This is probably not a bug with SOGo but with your installation. Do you have any sogo log file with this?
If you have an installation issue, you should fill a support request...

No, this is definitely not an installation issue.

There are no problems on 4 iOS devices nor on my Mac or a second Thunderbird client. Also the web interface is working for all parties perfectly.

The problem occurred by updating to the version shown above. The basic installation has not changed and all had worked before updating. Last update also update many SOPE packages as well.

I have done further testing this morning.

  • Using the iPad and creating a new test event inserts this into SOGo (checked with WebUI)
  • Opening the users Thunderbird client, the event is not shown (you get the error message talked about)
  • Resetting the calendar cache restarts Thunderbird and retrieves all data including the new test event
  • Pressing directly on reload external calendars brings back the error message shown above.

So in my opinion this does not look like a configuration issue, does it? ;-)

Here are the package versions:

ii libsope-appserver4.9 4.9.r1664.20120711 SOPE application server libraries
ii libsope-core4.9 4.9.r1664.20120711 Core libraries of the SOPE application server
ii libsope-gdl1-4.9 4.9.r1664.20120711 GNUstep database libraries for SOPE
ii libsope-ldap4.9 4.9.r1664.20120711 SOPE libraries for LDAP access
ii libsope-mime4.9 4.9.r1664.20120711 SOPE libraries for MIME processing
ii libsope-xml4.9 4.9.r1664.20120711 SOPE libraries for XML processing
ii sope4.9-gdl1-postgresql 4.9.r1664.20120711 PostgreSQL connector for SOPE's fork of the GNUstep database environment
ii sope4.9-libxmlsaxdriver 4.9.r1664.20120711 XML Parser for SOPE's SAX engine

dpkg -l | grep sogo
ii sogo 2.0.0.20120713-1 a modern and scalable groupware

Not pretty sure, but I found some threads concerning event race conditions.

I found out that this might be a conflict between iPad and Thunderbird and I have set

sogod SOGoiPhoneForceAllDayTransparency YES

After that I exported all addresses and events, killed the soho user with soho-tool and reimported all data and at least for today, the error messages are gone.

If this is the source of the problem, it still would be great, if Thunderbird would give a better error message than this stupid MODIFICATION_FAILED.

Please leave that bug open at least for some days and let me see, if the steps I did solved it forever or if the problem returns in nearer future. Thanks
