   > This is still an issue for me with latest 1.10.x and latest backport providers release.
   
   Hey @feluelle You likely have the old `azure-storage` library installed. The problem was that there were two libraries:
   * legacy (very old) "azure-storage' (https://pypi.org/project/azure-storage/) 
   * new - set of "azure-storage-*" libraries that replace the storage one. For example (https://pypi.org/project/azure-storage-blob/ or https://pypi.org/project/azure-storage-logging/). 
   
   The problem was that azure did a very, very bad thing. Both libraries have overlapping packages and they can override each other when both legacy and new libraries are installed. If you have 'azure-storage' and 'azure-storage-blob', the set of classes available in `azure.storage.blob` depend on which is the SEQUENCE of installing the two libraries and whethere they were installed with --force or not. Total mess.
   
   So if you want to bring the situation under control - remove 'azure-storage' and reinstall 'azure-storage-*' packages you have. That should help with the error.  If you install 2.0.1+ from scratch, the problem is gone (we have no more `azure-storage` dependency. However in 1.10 you need to install airflow without `[azure]` extra and then add 'apache-airflow-providers-backports-azure'.  Or remove storage and reinstall the 'azure-storage-*'.
   
   Let me know if either of those worked.
   
   I hope it helps. Maybe also someone could describe it nicely somewhere else in the docs ;) ?
