From many Outlook calendars to one useful team view

EGC is for organisations that need centrally managed calendar overviews without asking employees to maintain duplicate calendars.

1

Choose the source calendars

Select the users and group calendars that should participate in each overview.

2

Apply the rules

Use configured filters so only relevant meetings, absences or events are copied.

3

Use the managed Outlook view

Teams open one focused group calendar instead of comparing many personal calendars.

The problem EGC solves

Outlook already stores the appointments, absences and customer meetings your teams depend on. The difficulty is turning those personal calendars into useful team views without exposing unnecessary detail or asking people to enter the same item twice.

Too many calendarsManagers often have to open many personal calendars to understand availability.
Too much noiseFull personal calendars include items that are not relevant for a team overview.
Duplicate upkeepSeparate team calendars quickly become incomplete when employees forget to update them.

How it works in three steps

1. Choose sources

Select the users, group calendars and Outlook calendar folders that participate.

2. Set filters

Filter by user, group, category, subject, availability status or configured team rules.

3. Open the group calendar

Relevant items appear in centrally managed Outlook group calendars for the right audience.

Native Outlook sharing or Exchange Group Calendar?

For sharing one personal calendar, Outlook's native sharing may be sufficient. Exchange Group Calendar is built for organisations that need centrally managed views across multiple Outlook calendars.

Native Outlook sharingGood when one person simply shares one calendar with another person or a small group.
Exchange Group CalendarBetter when administrators need managed team views, group membership and filtering rules.

Graph for Microsoft 365, EWS for on-prem Exchange

Use the standard Graph trial for Microsoft 365 and Exchange Online. If the customer uses local Exchange Server, request the EWS edition so we can send the correct package and installation guidance.

OOO · Client meetings · Team events

Use one clear group calendar per purpose. The point is not to show more calendar information. The point is to show the right calendar information.
