Long Live the web page..

Posted on: December 5th, 2019 by

You may have seen that we had some issues with our website front page ‘https://kolabnow.com/’ this afternoon, and that it was on and off a few times.

Yes! We did some updates on the themes and color pallets. We had the new update up for a short while, but found out that our designer had ‘made a boo boo’. It took a little time to fix it and get the colors right, but everything is ok up and running again now.

During this update we did not touch the actual service ‘https://kolabnow.com/apps’ or anything even close to the data – only the front page ‘web blah’. If you were just reading your mail and going about using the service, then everything was just working as it should. Chances are, that you did not experience any issue at all.

If you were looking for anything on the front page at exactly that moment where we were moving things around, then we apologize for the inconvenience.

 

DISCLAIMER: No bits died or were hurt during this update.

Incident Report: Double trouble..

Posted on: October 28th, 2019 by

Late Sunday night at 21:31 CET we were alarmed by lost connections. Symptoms seemed to point to a networking issue in the datacenter. Our datacenter provider was alerted, we sent our own emergency team onsite to assist in resolving the issue, and to deal with any fallout.

A faulty firewall was recovered, and mail started flowing again at around 00:10. Our ops team is now investigating why the firewalls didn’t fail over as they are configured to do in such situation.

At about 04:15, long after the system had recovered from the firewall issue, one system started to throw disk errors, which was leading to some users not being able to access the data in their folders. As this was a separate issue, the symptoms were only discovered at around 06:45, as it was assumed to be recovery issues from the previous outage. As soon as the disk error issue was realized, it was fixed and recovered. Connection to data was available again for all users at 07:10.

Where as we are still investigating the root cause for both of these issues, we can state, that no data was at risk at any time during the events.

We apologize for any inconvenience this has caused.

Mobile friendly webmail is here and brings some changes

Posted on: September 2nd, 2019 by

We are happy to announce the coming release of our mobile friendly skin for Kolab Now. From 14th September 2019 on, your webmail will look a bit different. With the new skin, you will finally be able to use Kolab Now webmail with the browser on your phone. Check out our previous post for more information.

The default mail deletion behavior changes

We decided that the switch to the new skin would be a good opportunity also make another much requested change. We change the default way of deleting emails in the webclient.
Going forward, when you click on Delete, mails will be moved to your Trash folder, and you can then decide when to ’empty the trash’. Previously, deleted mails where only marked for deletion and hidden immediately without an obvious way to undo, and the hidden mails stuck around, clogging up your storage quota if they were not expunged. This led to a couple of support cases over the years. After some user testing we decided to go with what people are used to from other email clients and providers.

Our website gets a long needed update

Our website has been out-dated for quite some time so we decided to give it a major overhaul. For now, it is reduced to the bare necessities and we will add more content when needed. It should now be easier to find essential information and get access to support – among other things.

 

Feedback is always appreciated

We hope you like the changes we have been working on. Give us feedback by writing to support@kolabnow.com

Rate Limits Are A Thing Now

Posted on: April 15th, 2019 by

We’ve been dealing with quite a number of spammers whom register accounts with us, and start spamming third parties.

As you might imagine, our environment is geared toward redundancy and load-balancing and high traffic — hundreds of messages, thousands of recipients, every minute. The capabilities of our infrastructure are therefore in and by itself not limiting the rate at which anyone can send any number of messages to any number of recipients.

But, this is the case no longer per se.

Another iPhone ‘LIST-STATUS’ issue..

Posted on: February 13th, 2019 by

A little more than a year ago, we found and worked around an issue that caused iPhone users to have problems with IMAP connections to Kolab Now. The issue made it problematic for such users to list and read their IMAP folders.

Back then we worked around the issue by suppressing the LIST-STATUS option for IMAP connections, which made everything work for a while.

This week we again started getting a number of reports about similar symptoms from iPhone users, and we of course investigated those reports as fast and appropriate as we always do.

We quickly found, that a change was made in January to fix an issue for  Outlook users, and that one part of that change was – you guessed it – to undo the suppression of LIST-STATUS. Hence, IMAP connecting iPhone users were getting right back into almost the same situation that they were in a year ago.

Where as we have found the root cause of the issue, we seem to be in a catch 22, where we can accommodate Outlook users or iPhone users connecting via IMAP. Of course we are working on a fix that can make it possible to accommodate both groups of users. Updates and news about the issue will be posted here in this blog.

If you need to read mail and list mailfolders on your iPhone before we have fixed the issue, there are at the moment two workarounds:

  • You can change your iPhone to connect via ActiveSync. This will require that you have Mobile Connectivity enabled in your subscription.
  • You can set your web client to use the new responsive skin, and then open the web client in a browser on your iPhone.

Should you have any questions or concerns in this context, then please contact Support.

The Kolab Now Team thank you up front for your patience.
