In the beginning of the week we got a list of reports from users of iPhone connected via IMAP. These users reported that they were unable to list their mail folders. You can read about this issue in a previous blog post on this blog.

Outlook and return options to LSUB
A while back, users started to experience issues with IMAP LIST Extension for Special-Use Mailboxes. This to a level where a decision was made to temporarily suspend supporting Special-Use at Kolab Now.
Lately we have found ways to get around the problems that were present back then, and over the change of the year we introduced an update that, among other great improvements, contained these solutions and re-enabled the Special-Use.
Unfortunately, meanwhile Microsoft has also updated Outlook, and their update has changed the return options that Outlook is using with the LSUB command on the IMAP server.
This has caused issues for some users, who connect Outlook to Kolab Now via IMAP. Those users are suddenly not able to see some of their folders and mails in Outlook. The folders are perfectly visible in the web client and in other IMAP clients like mobile clients, Mac Mail and Thunderbird.
While the RFC compliance issue (the LSUB command does not accept a client specifying RETURN options) certainly has been made visible by Microsoft changing the behavior of Outlook, inversely Kolab Now providing an update to the benefit of all other clients has suddenly shown the related Outlook behavior to be faulty.
The root cause of the issue can be narrowed down to the expectations from Cyrus IMAP while parsing the LSUB command. Besides filing an upstream ticket, Kolab Systems has engaged in this issue and is contributing a fix to the Cyrus IMAP code. This fix is now going through test and QA, and should be ready to be deployed to Kolab Now soon.
If you are one of the users, who has problems because you are connecting Outlook to Kolab Now via IMAP, then you can work around the issue by – either using another IMAP client – or by connecting your Outlook to Kolab Now via ActiveSync, until the fix for Cyrus IMAP is ready and deployed.
If you have any questions or concerns in this context, then please contact support@kolabnow.com.
A New Gregorian Year, A New Responsive Skin
The change of the year is always a good opportunity to look back at what has happened, and to make changes for the future. Earlier we have been writing about the work put into the Responsive skin (elastic skin) and it’s now time to enjoy the result we got out of the work that was done.
A version of a responsive skin was available on beta.kolabnow.com/apps for a while, but now it has finally passed QA, and is made available for all Kolab Now users.

The end of short logins..
In our ever ongoing effort to improve the service and get rid of legacy, we are again removing old infrastructure and replacing it with new. Where as this is seamless and invisible to some users, we have seen that others are running into – e.g. login issues.
Kolab Now Responsive Skin
We’ve received many requests to make the web client more useful on mobile devices, so we’ve put some of our development focus on a responsive skin for the Kolab Now web client, and in turn Kolab. The result already got great feedback from the early adopters, now the skin has been updated with fixes and additional functionality.
To test the new skin and functionality, please go to: https://beta.kolabnow.com/apps/ and login with your Kolab Now user login.
