To detect inactive workspaces, ShareGate looks for user or system-generated activity and extracts the dates of these activities.
User-generated activity can occur when a member modifies a document or when an admin uses ShareGate Migrate to copy a SharePoint site.
System-generated activity can occur if you have automated system messages in Teams, for example.
Note: Team messages that originate from webhooks aren't considered activity. Inactive workspaces won't be considered active due to automated messages coming from third-party applications.
ShareGate crawls for activity in the following associated workspaces:
Outlook conversations
Delivery dates of email conversations.
Outlook Calendar
Creation and Last Modified dates for both recurring and non-recurring events.
SharePoint
In the SharePoint admin center, the Last activity column for Active sites.
In a group's SharePoint site, changes to the Site contents Modified column.
Activity in the associated SharePoint site of a team's private channel.
Teams
Message and reply dates (creation and edits).
Message and reply reaction dates.
ShareGate checks to see if the most recent activity exceeds the 180 days determined for inactive workspaces.
A workspace is deemed inactive if all its associated workspaces show no activity in that set period of time.
Note: An associated workspace is not considered if ShareGate does not have access to it or if it is not present for your workspace. For example, Teams may not be enabled for all your Microsoft 365 groups, or ShareGate may not be able to crawl Outlook calendars in private groups unless you are also a group owner.
