Handle 409, `ErrorFolderExists` error in restore path while creating destination calendar. We need to fix this for all m365 services. This PR is focused on calendar only. Context: `CreateCalendar()` may fail with ErrorFolderExists under certain error conditions. For e.g. consider below scenario. 1. `CreateCalendar()` does a POST to graph to create restore destination calendar but this fails with 5xx. 2. It's possible that step 1 may have left some dirty state in graph. For e.g. it's possible that the destination folder in step 1 was actually created, but 5xx was returned due to other reasons. 3. So when we reattempt POST in such a scenario, we sometimes observe ErrorFolderExists error . 4. Corso should be resilient to such errors. To fix this, when we encounter such an error, we will do a GET to fetch the restore destination folder and add it to folder cache. --- #### Does this PR need a docs update or release note? - [ ] ✅ Yes, it's included - [ ] 🕐 Yes, but in a later PR - [x] ⛔ No #### Type of change <!--- Please check the type of change your PR introduces: ---> - [ ] 🌻 Feature - [x] 🐛 Bugfix - [ ] 🗺️ Documentation - [ ] 🤖 Supportability/Tests - [ ] 💻 CI/Deployment - [ ] 🧹 Tech Debt/Cleanup #### Issue(s) <!-- Can reference multiple issues.

Corso
Corso is the first open-source tool that aims to assist IT admins with the critical task of protecting their Microsoft 365 data. It provides a reliable, secure, and efficient data protection engine. Admins decide where to store the backup data and have the flexibility to perform backups of their desired service through an intuitive interface. As Corso evolves, it can become a great building block for more complex data protection workflows.
Corso is currently in Beta.
Corso supports M365 Exchange and OneDrive with SharePoint and Teams support in active development. Coverage for more services, possibly beyond M365, will expand based on the interest and needs of the community.
