Guys, I have been looking around at backup solutions for Exchange online. We are on the M365 E5 license. We are told Exchange Online doesn't offer traditional backup. I wish to be able to restore deleted mail 7 days out (i.e. mail that's been deleted from deleted items). Whilst unlikely a user would do this it's still possible and I need to account for it. Doing some reading though, Exchange Online offers unlimited archiving and hold on all mail as per this link.
So my question is, can a hold be used for this purpose i.e. hold for 7 days? Can folders be restored i.e. folder structure if a user was to delete the folder structure?

By default, Exchange Online keeps permanently deleted items (i.e. deleted out of deleted items) for 14 days by default, but this can be changed to a maximum to 30 days - this is for all mailboxes.
In terms of backup - what kind of backup are you looking for? You may want to focus in on Retention Policies if there is certain data you want to ensure is not deleted; alternatively, there are some third party services that act as a more traditional backup.

Thanks for the reply @Chris Webb . I'm new to O365. Do retention policies prevent users deleting mail though? Also, do they protect against malware corrupting mail i.e. is the mail immutable?
