<p>Download the 0.8.3 rpm if you don't have it locally and do</p>
<p>yum downgrade guam-0.8.3-2.1.el7.centos.kolab_16.x86_64.rpm</p>
<p>I also blocked updates to guam for now with versionlock</p>
<p>yum install yum-plugin-versionlock.noarch<br />yum versionlock add guam<br />yum versionlock list</p>
<p>guam 0.9.2 is just plain broken. There is also this post in the forum <a href="https://kolab.org/hub/topic/264/guam-error-after-update-to-0-9-2">https://kolab.org/hub/topic/264/guam-error-after-update-to-0-9-2</a></p>
<p>Also the KolabNow service only recently implemented Kolab16 including guam (don't know what release) and they had to disable it after only a few days of use (https://kanarip.wordpress.com/2017/07/03/kolab-now-disabled-imap-proxy/).</p>
<p>Winterfell only has guam 0.9.0 in it. This puzzles me as I thought that Winterfell was supposed to be the development repo, so I do not understand how/why the Kolab16 repo would have a later version. Winterfell does have a later version of erlang, so maybe there is a version incompatibility?</p>
<p>We have also had to disable Wallace at it constantly (several times a week on a 50 user system) stopped processing emails.</p>

<p class="MsoNormal"><span style="font-size: 11.0pt;">I would think so. Guam will crash and then restart so lots of spinning wheels on user's screens. It wasn't just the slow performance for us. We have a mix of systems and clients. Macs were Ok with Outlook, but Windows PC's (7&10) would not work at all with Outlook. Thunderbird was fine on Windows.<!-- o ignored --></span></p>
