### Info
- Used Zammad version: 3.3.0-19
- Used Zammad installation docker
- Operating system: CentOS
### Expected behavior:
- Add a new channel
### Actual behavior:
- Error message “FETCH failed: Storage corrupted”
### Details
I had a channel previously, but because of the email server issue we delete it from Zammad and now we are trying to add it back.
We have 5 other channels and everything is working Ok except that while I’m trying to add the new channel with the same email address that was used before I’ve got the error “FETCH failed: Storage corrupted”.
Added any other email is working.

These error messages usually come from your mail server.
Did you try to login to the affected account with e.g. a Thunderbird? If so, does it work?
If this is a selfhosted mail server, checking it’s logfiles for the word `corrupted` may help.
For me personally I’ve never seen such an error message, but well, you always learn new stuff. 😉

Yes, me too.
Mailbox is working. We use it from a web interface every day. I checked the mail server (we use Axigen) logs and didn’t find any errors. Restarted everything just in case and nothing…
So I made a workaround. Created a new email box and set up a forward rule from the original box to the new one. Then added the new one to the Zammad.

Really odd.
Glad you could somehow solve it.
