Outlook and return options to LSUB

Posted on: January 9th, 2019 by

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.

Our statistics for 2018

Posted on: December 31st, 2018 by

Our terms of service state there’s basically no way for anyone to get any access to your data without us also being able to talk about the fact it happened, and further down nested in our legal framework outline do we have a list of 3 general types under which individual requests could be filed.

I recall that some place, we also promise to at least publish the statistics. I don’t recall where, but I seem to remember we have. In any case, here’s our summary for 2018.

A New Gregorian Year, A New Responsive Skin

Posted on: December 29th, 2018 by

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.

Our October Silence?

Posted on: November 7th, 2018 by

Hi there,

I just wanted to provide you with a quick note that our blog roll’s “October silence” is nothing but just that. Some of us became a father to a son, have needed to deal with some citizen/resident paperwork, some of us choose to entertain the fresh snowfall way up the Alps, others took some vacation time, and such and so forth.

In the all-work-no-play area, I think we’ve figured out webmail decryption/signing, a responsive skin to be made available to mainstream Kolab Now, new exciting service venture definitions even though still under development, and we have now been able to deal with our midterm election anxiety (albeit November 25th could incur some implications domestically).

Incident Report: Thursday, 20:25 – Friday 01:15 UTC

Posted on: September 21st, 2018 by

Last night, a failure in the storage layer caused most of our services to be unavailable. In the week before, we replaced a failed hard drive. In the week before that, a so-called Virtual Fabric Adapter failed, causing a hypervisor to shut itself off. Since the most recent incident was the more serious downtime, that’s what we’ll start our reporting on.

Kube Campaign: Last Chance

Posted on: August 29th, 2018 by

The proposition of the Kube campaign is the following:

You sign-up now via Kube for a Kolab Now account, and pay only for the currently available feature-set that Kube provides at the moment. The web client will be limited to the same feature-set, but as Kube progresses and covers more features you will also get those features for the web client, while you get to keep your reduced subscription price.
