About

Keeper.sh is a calendar syncing tool that helps you stop double-bookings, and increases your organizational capabilities: compatible with Google Calendar, Outlook, Microsoft 365, Apple Calendar, Fastmail, CalDAV and more. It syncs events in realtime, allows you to redact information so you only sync what you want, and helps you connect your calendars to your agents through a convenient MCP server and optional API. If you'd like to share your calendar with the privacy and calendar filters of your choice, you can also generate as many ICS links as you want. Keeper.sh has a convenient managed solution, but for privacy conscious users or technical hobbyists, it is open-source under AGPL-3.0, where you can get all premium features for free.

Pros & Cons from Real Users

Pros

  • Amazing integration with Microsoft office apps & services. Calendar sharing & scheduling capabilities for collaboration.
  • The best part is its integration with other Microsoft applications, due to this function the workflow becomes very smooth.
  • There are a lot of Pros some of them are its email management options like advanced filters, email categorization, sync with other Microsoft tools like Microsoft teams, Calendar & scheduling. Also its user friendly which is a great thing for new users & there are a plenty of tools embedded which helps you customize & manage your emails.
  • It integrates seamlessly with other Microsoft products, has computer, mobile, and web versions that all work well, and is a great option for work email. I have especially been a fan of the Zoom integration! It's easy to use and does everything I need to (and then some) for my job.
  • I've utilized outlook for years throughout multiple roles within the same company. It is a great hub for everything including emails, integrating with other Microsoft tools, and is visually very easy to navigate.

Cons

  • Interface can be cluttered & overwhelming for basic email needs. Lack of automation & CRM features compared to other business email tools.
  • The only thing i feel as a con is its interface seems a bit outdated, as compared to its competitors.
  • We frequently see a delay in updating our email box, apart from that Microsoft Outlook seems a perfect tools for professional collaboration & communication.
  • I honestly do not have a major con. The only thing I can think of is that the layout of where features are varies depending on what device I am using, so it can be difficult to find certain things. However, this is really minor!
  • I haven't found a way to integrate Gmail and Outlook features that I like in tandem, but it could just be user error.
