Cloudron has a built-in mail server that can send and receive email on behalf of users and applications. By default, most of it's functionality is disabled and it only sends out mails on behalf of apps (for example, password reset and notification emails). Hypha has enabled Cloudron Email and offers a full-fleged mail server solution. Each user gets a mailbox username@domain and can send mails using SMTP and receive mails using IMAP. Users can also setup server side mail filtering rules using ManageSieve.

How to create aan Zoomemail meetingaccount

As you recall, every circle has one Zoom license, so it is important to log into Zoom under the correct Zoom account for your circle. All login credentials are maintained in Locker, if you do not have access to Locker, please set up a Locker account first (see below).

After you have successfully logged into Zoom, you can schedule your meeting. Click on Meetings and then on Schedule a Meeting. Fill in the form and pay attention to the following fields:

  • Timezone: Always set this to GMT +0.00 UTC (this will avoid the Daylight Savings Times issue)
  • Recurring meeting: click on the checkbox, if you repeat this meeting every week (set to weekly and give it an end date or the number of occurrences in the dropdown, eg. "20")
  • Security: Check "passcode", it will automatically generate a link with the password attached

It is not necessary to have the host be present at the meeting. However, you can share the host code with your team so host features are available (incl. recording and break out sessions). To share the host code, click on Profile and scroll down to Host Code. 

After you have created your meeting, you need to share the invite on the Hypha Google calendar.


To add the invite to the correct calendar, you need to do two things:

  1. If the  Hypha Calendar Account  is NOT open, switch your Google calendar to the Hypha Calendar Account by clicking on the avatar on the top right of the calendar view (you will see a Hypha logo like shown below). If you need login credentials to the Hypha calendar Google account, please go to Locker
  2. If the event you scheduled is not open, find and open the invite that you created and switch the calendar to the correct Google CIRCLE calendar (see dropdown next to the calendar icon below).
  3. Save the calendar event.



How to set up a Locker account is our secure vault to store all important Hypha usernames and passwords for shared services. Please decide who can access the passwords for Zoom and Google accounts in your circle. While we suggest the Lamp Lighter is a good candidate, it can be anyone in the circle. It is good practice to grant 2-3 people access to the passwords. To request access to Locker and the passwords, please Direct Message one of the maintainers below. You will receive an invitation link to Locker with a list of passwords for Zoom and the Hypha Google calendar account. Locate the Zoom passwords and the Google calendar passwords in the list (see below, each circle has its own login credential). 



For the Hypha Google calendar (and other tools that require higher security), you may be prompted for 2-factor authentication (2FA). If this happens, click the copy icon next to the 6-digits counter underneath the password. Use that to paste it into the Google form that is asking for this second protection layer. This is triggered by Google to prevent unauthorized access to accounts and will usually no longer be necessary on subsequent logins. 

If the counter is getting close to zero it will change to red. Wait for the next cycle before your copy and paste the 6-digit code.

Frequently Asked Questions

What if I can't log in?

Make sure you have access to Locker (see above) and use the correct username and passwords. We have different logins for Google and Zoom, so make sure to pick the right one when you log in. Also note that Google is asking (from time to time) for additional verification (called 2-factor authentication) and Locker will provide this as well (see screenshot above). 

What if I accidentally double schedule?

Our Zoom license does not allow to schedule two meetings at the same time. Make sure you check the current calendars for any overlaps before you schedule your meeting. If for some reason an overlap occurs, Zoom will detect it and close the other meeting once a host has started the new (overlapping) meeting. 

What if my calendar isn't syncing with Zoom?

Syncing calendars with Google is a one-way direction - once you have scheduled the meeting and "pushed" it to the Google calendar, it stays there. Any updates in Zoom will NOT be reflected on the Google calendar. To make changes, either edit the Google calendar directly or delete it and push another update to the calendar from Zoom. 

What if my circle needs more licenses?

Hypha has a limited amount of licenses available at this time. Unfortunately, we cannot increase the number of licenses but we can revisit this once the current licenses need to be renewed early 2022. The current licenses are maintained in this file by dStudio.
