Subset of mailboxes failing to backup with error: The remote server returned an error: (500) Internal Server Error

Post by mattbrown80 »

Strangely, this job didn't exhibit any issues and has been running for quite some time, and then a subset of mailboxes (~30 mailboxes, out of 200) started to fail with this error:

3/7/2024 2:26:03 PM :: Processing mailbox <mailbox> failed with error: The remote server returned an error: (500) Internal Server Error.

We opened a Veeam case and support seems to think it's a network issue, but we have several hundred other jobs in the same environment, behind the same network stack that are not exhibiting this behaviour.

The veeam case is 07157926
Please help! Veeam support appears to be stumped and has been working on this for 8 days

Hi Matt,

I'll get in touch with support to see if RnD needs to be involved to resolve your issue.

@mattbrown80 did you ever find a resolution to this error? I just started seeing the same error 500 on a few of my mailboxes overnight.

Hi spritchard81, welcome to the forums.

The topic creator's case identified that the issue was outside of Veeam and related to other items in the backup infrastructure, but it's best to open a Support Case and let the Support Engineers review the situation, as at least with the TC's case it was not related to Veeam specifically, so probably it's best to get a fresh look at your situation; Error 500 is just a generic HTTP/REST error returned so difficult to tell from just the error what might be throwing that in your environment.

Please share the case number here once you've opened a case, thanks!

Thanks David, I restarted the jobs this morning and they all completed successfully. Appears to be a temporary error so I did not open a support case yet, I will follow up if it continues to happen.
