Summary
Reference
If you want to stop using(decommission) SM environment you can shutdown servers and that’s it.
Important points:
1. VEC caching – if someone is using their environment it is possible that email will be composed with cached data for max 2 weeks.
2. Old messages - Once SM environment is not online, you will also not be able to open encrypted messages
- solution: decrypt old messages with eDiscovery – you will need to purchase it – or use VEC option to store messages decrypted once opened but you need to click on every encrypted email in outlook.
These 2 are required to decommission SM environment.
