Veeam Explorer for Exchange and Exchange 2016 CU5

So, a quick note for those with the above software – I’d recommend you trying to access an EDB (Exchange Database) file from one of your backups with Veeam Explorer for Exchange at your soonest convenience – it appears that there is an incompatibility with Exchange 2016 Cumulative Update 5 (that Veeam Support were aware of) which results in an inability to view the individual files.

If you’re being hit with this issue, you’re likely to see this delightful error…

Veeam Exchange 2016 Blob

Invalid property BLOB.

Moreover, your logs (over in %ProgramData%\Veeam\Backup\ExchangeExplorer\Logs) will show this delightful extract…

Word is that the problem will be fixed in “Update 2” from Veeam, but they’re estimating this could be a few months out. Best practice right now? Either avoid upgrading to CU5 or if you have deployed it, you’ll need a third-party tool to extract the data (the backup itself is fully functional and unaffected).
