Fixed
- Check if the user specified for an exchange backup operation has a mailbox.
- Handle case where user's drive has not been initialized
- Inline attachments (e.g. copy/paste ) are discovered and backed up correctly (#2163)
- Guest and External users (for cloud accounts) and non-on-premise users (for systems that use on-prem AD syncs) are now excluded from backup and restore operations.
- Remove the M365 license guid check in OneDrive backup which wasn't reliable.
- Reduced extra socket consumption while downloading multiple drive files.
- Extended timeout boundaries for exchange attachment downloads, reducing risk of cancellation on large files.
- Identify all drives associated with a user or SharePoint site instead of just the results on the first page returned by Graph API.
