# Error message "No provider available for protocol email"

This error message may be displayed for a number of reasons:

The filters used do not match the account they are associated with.

This happens when the filters.xml file is copied and used on a fresh install of Evolution on a new machine.

Accounts have unique ID numbers, and filters refer to these accounts directly. Simply copying the filters.xml file will cause a version mismatch with Evolution, affecting the filter rules.

The account settings may not have been copied properly.

The account settings were modified.

To fix this problem, edit the email filters and re-select the folder for each Copy/Move filter. To do this:

Go to Edit Message Filters.

Select the Copy/Move filter and click Edit.

Refer to the list of folders associated with that particular filter. Click on the button that allows you to modify the folders assigned for that filter. Set the folders again.
