Cannot find blob containing item data when exporting mailbox (Veeam Backup for Microsoft 365, S3 repository)

[deniz.oezdemir]

Hi everyone,

I am running Veeam Backup for Microsoft 365, and I created an S3-compatible, Item-Level repository with a 7-day retention period.

The backup job completes successfully, but when I try to export some mailboxes, I get the following error:

Code: Select all

Cannot find a blob containing item data:
Veeam/Backup365/test-incremental-backup/Organizations/<org-id>/Mailboxes/<mailbox-id>/ItemsData/492E870E08DE7AC9000005D7.0002

Observations:

• Some mailbox exports work, but others fail with this error.

• Older restore points also fail.

What would cause this error, and how can I fix it?

Any advice would be appreciated.

Thanks!

Hello,

We had a similar issue once, but it was fixed in v8.1.2.180.

Since this is a technical issue, please contact our Customer Support team — we can’t investigate these cases via a forum topic. Also, please provide a support case ID for this issue (as requested when you click New Topic). Without a case number, the topic will eventually be deleted by moderators.

Thank you,
