We're migrating from ProtonMail/Nextcloud to Infomaniak specifically because we need standard protocol support (IMAP, CalDAV, CardDAV) that works with third-party services. The irony is that ClickUp, one of our most critical tools, doesn't support CalDAV either.

Right now the only way to see external calendar events in ClickUp's Planner is through Google or Outlook, which means routing all our calendar data through US Big Tech servers. For teams that chose privacy-respecting European providers (Infomaniak, Posteo, Mailbox.org, etc.) specifically to avoid that, this is a dealbreaker.

ClickUp already has an official MCP server and just launched "Connect any MCP" support. Infomaniak has published their own Calendar MCP server. So the AI-powered read/write path works. But there's no reason the visual Calendar/Planner shouldn't support CalDAV too. It's a 30-year-old open standard that every serious calendar provider supports.

CalDAV sync would unlock ClickUp for the growing number of teams moving away from Google/Microsoft for privacy, sovereignty, and GDPR compliance reasons. Please prioritize this.

Too bad that the topic has been open since 2019..! For us, this is actually a pain point because we don't want to use Outlook or Google for our calendars. From our point of view, CalDAV is really a must these days...

+1 asap

Why it's still not implemented! It's joke in these days...

CalDAV support is basically a must-have for any calendar integration these days and I don't understand why this isn't already baked into the system. I'm in trial mode and not likely to pay for ClickUp if I can't integrate my calendar, which isn't Outlook or Google.

Hello,

Have there been any developments regarding CalDAV integration?

There are so many solutions on the market; limiting this to Outlook and Gmail, especially for a company that values confidentiality, seems unreasonable. Proton Calendar and Infomaniak Calendar, for example, can all be used via CalDAV.

Kind regards

Caldav is one of the open standards that allows the use of more private and adapted systems, on premise and hybrid. All the more so in these times when the security, confidentiality and sovereignty of data is becoming critical for people and businesses. For example for me and my customers, the servers and NAS services from synology. Clickup's interointeropera with open and non-proprietary computer standards like Caldav is just a MUST HAVE! Thanks to you

Yeah, CalDAV 2-way Sync in the new calendar (which is nice btw) would be really great. There’s a world outside of Google and Microsoft.

+1 on CalDAV. Please always support open source solutions ClickUp or I will always be looking at other options.

+1 for CalDAV 2-way sync
