With everybody slowly moving to cloud-based solutions. Moving your email system from an on-premise solution to the cloud might be an obvious choice.
Be that as it may, there are aspects which tend to be overlooked when migrating.
One of the major things to be overlooked is backups. You can theoretically restore data and emails from Office 365 but there are caveats. Office 365 keeps your data in a “Litigation Hold”, which saves copies of emails and data to a “Recoverable Items” folder within the program (this is hidden from most users). This has major issues if you were to use this as a primary backup source.
Litigation Hold is mainly for discovery email discovery rather than restoring, it doesn’t create a copy in a different physical location (so this doesn’t provide any protection against ransomware or hardware failure), you can export the data but there is no inbuilt recovery process, so in a disaster scenario, restore times can take considerably longer as it has to be imported and exported manually. Since all data is being saved to the same machine, the data may need to be deleted manually, for larger organisations the additional data that is stored can cause considerable performance degradation.
For deleted items you can set the retention policy to “Unlimited” so no data is deleted, Office 365 defaults to 14days. Recoverable Items again defaults to 14 days but up to a maximum of 30days, after 30days the data is then deleted forever.
