Team Availability Calendar
Virto Calendar App draws every team member's calendar in one Outlook view — busy time, vacations and shared meetings, under the permissions each source already has.

Stress-free scheduling with Virto’s Availability Calendars
Teams normally keep separate calendars. Virto Calendar App reads them together.
Everything in one place
Virto Calendar App overlays meeting rooms, project timelines and team calendars. A Task (hours) timeline lays each person's commitments out side by side, so a lead reads the week as a resource picture rather than a grid of squares.
Just want to create an availability calendar fast and share it with someone outside your org? Pop one into Microsoft Teams and send them a link—done and dusted.

Sharing schedules made easy
Set up detailed permissions so external users only see what they’re supposed to—perfect for teams that take calendar security seriously. Great for sharing schedule of availability with partners, vendors, or clients.
Share a link with anyone outside the organisation — no account required.

Custom, clear & secure
Colour-code by person, filter by team and keep every source under its Microsoft 365 permissions. Virto Calendar App reads the calendars a team already shares, and shows nothing a source does not expose.
Tag it, sync it, share it — updates in real time.

Key benefits
Overlaps show up before they are booked
Because every member's busy time sits on one grid, a clash is visible while the meeting is still being planned — not after the invitations go out.
Your schedule, always current
The view stays current as the source calendars change, so a colleague checking whether a slot is free is reading the same picture as the person who owns it.
Easy sharing with outsiders (no logins required)
Need to share your availability calendar with someone outside the company? Virto lets you send a simple link—no Microsoft account, no hoops to jump through. Or, if you like control, set up detailed permissions. Either way, it's the easiest way to collaborate with vendors, clients, or freelancers.
See everything at a glance
Color-coded views = instant clarity. With one look, you can tell what’s booked, what’s free, and where your team stands. That means fewer misunderstandings, faster planning, and a calendar to show availability that actually makes sense.
Reminders keep the view current
New bookings, cancellations and recurring events show up as the source calendars change; approvals stay wherever they happen today.
Each calendar keeps its own permissions
Virto Calendar App reads what a person already shares with the team and nothing beyond it. The view follows the access model of the source calendar, not a separate copy of it.
Which Virto Calendar Is Right for You?
You’re running a large organization with dozens of meeting rooms, team schedules, and gear to manage.
You need an availability calendar that reads Outlook, SharePoint and Planner in one place. Colour-coded overlays and filters show an overlap while the meeting is still being planned.
Your growing company shares a few conference rooms and devices across one office.
You want a calendar availability tool that plays nice with Microsoft 365 and lets you control who does what, down to the minute.
You’re solo and just need to show your schedule of availability to clients who don’t use Teams or Outlook.
Real-time updates, easy sharing, no logins, no licensing headaches. Just a clean calendar to show availability.
You’re juggling multiple venues, vendors, and timelines all at once.
Several venues and vendors keep their own calendars. Virto Calendar App draws them in one view, so a planner reads one timeline instead of five.
You’re coordinating volunteer shifts and shared events with external partners.
Create and share availability calendars without forcing folks to log in. It’s inclusive, accessible, and perfect for community-driven teams.
