Resources removed
The following resources are removed after 30 days:

Analytics rules
Bookmarks
Your playbooks, saved workbooks, saved hunting queries, and notebooks aren't removed. Some of these resources might break due to the removed data. Remove those resources manually.
After you remove the service, there's a grace period of 30 days to re-enable Microsoft Sentinel. Your data and analytics rules are restored, but the configured connectors that were disconnected must be reconnected.
Microsoft Sentinel tables deleted
When you remove Microsoft Sentinel from your workspace, all Microsoft Sentinel tables are deleted. The data in these tables aren't accessible or queryable. But, the data retention policy set for those tables applies to the data in the deleted tables. So, if you re-enable Microsoft Sentinel on the workspace within the data retention time period, the retained data is restored to those tables.
The tables and related data that are inaccessible when you remove Microsoft Sentinel include but aren't limited to the following tables:
