Veeam Explorer for MS Exchange - Invalid seralized stream

[zer0]

Hi there,

we currently backup our "Veeam MS365 Backup" VM to our Veeam B&R repository. When accessing our backup of the VM on B&R repository via "Restore application items > Microsoft Exchange Online mailbox items" it will correctly open the store and show the usermailboxes BUT when we want to show/list the items in the folders we receive following error:

"Invalid serialized stream, unknown opcode found:4"

Veeam MS365 Backup has version Veeam Backup for Microsoft 365 7a P20240418 7.1.0.2031 12.1.0.2031
and our B&R Server 12.2.0.334

any ideas how to fix the issue?
