Cal.com Reviews

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • Change SharePoint Start Page for All
    When our users go to office.com, login and click the waffle for SharePoint, I want to change this landing page. Right now, it goes to https://ourdomain.sharepoint.com/_layouts/15/sharepoint.aspx and once users are in SP, if they ever click the home button it will direct them to this page as well. I want to change this to a new site we created that makes browsing our sites and sharing information/events much... Source: 6 months ago
  • Has anyone seen same behavior with AAD laptops reaching out to internal DCs on ports 88, 389, and 445
    Authentication happens through a 3rd party so when we try to login to office.com with our company accounts it redirect us to this 3rd party company that handles our logins. Source: 6 months ago
  • Where is the Copilot in Excel?
    I've looked in office.com (using Chrome) and Excel 365 for Mac (Version 16.79). Nothing in the top-right corner except "Analyze Data". And when I try to search for in the the Tell Me or Help menu, it acts like it has no idea what Copilot is. Source: 6 months ago
  • Autopilot "other user" login. Also "incorrect password".

  • Start your own (side) business with open-source in mind
    Cal.com is an open-source event-juggling scheduler for everyone, and is free for individuals. - Source: dev.to / 3 months ago
  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: 6 months ago

    Has any one deployed cal.com with selfhosted environment. Is yes how would have configured prisma for the same. Source: 8 months ago
  • Open Source, EVERYTHING??
    Recently I came across a company called cal.com, it's a Calendly alternative, but the catch is the entire software is open source: https://github.com/calcom/cal.com. Source: 8 months ago
