Connect Microsoft OneDrive

PratikYedek uses OneDrive's App Folder scope (Files.ReadWrite.AppFolder). We can only access a dedicated folder at the root of your OneDrive — your personal files are not accessible to us.

Prerequisites

A personal or SME plan (tax-advisor plan is restricted)
A personal Microsoft account (consumer) or Microsoft 365 (work/school)
At least 1 GB free

Step 1 — Open Storage settings

Sign in to PratikYedek
Navigate to Settings → Storage
Click Connect OneDrive

A new browser tab opens with Microsoft's consent screen:

App: PratikYedek Yazılım (Azure AD multi-tenant)
Permission: "Have full access to its own files" (Files.ReadWrite.AppFolder)
Sign-in: Use your existing Microsoft account or sign up

Approve to continue. Microsoft creates a folder named "PratikYedek" at your OneDrive root the first time.

OneDrive may store data in EU regions:

Consent modal lists region (EU primary)
Explicit cross-border transfer acceptance (KVKK § 9)
Logged with timestamp + IP

Step 4 — Token rotation (mandatory)

Microsoft mandates token rotation every 24 hours. PratikYedek handles this automatically:

Refresh token rotated on every API call (in-memory)
Rotated refresh token persisted via Drizzle (encrypted at rest)
If rotation fails (account locked, MFA challenge), banner appears: "Reauthorize OneDrive"

Step 5 — Connection test

Same as Google Drive — write/read/delete probe → green checkmark.

Step 6 — First BYOS snapshot

Encrypted chunks are uploaded to your OneDrive's "PratikYedek" App Folder. Only metadata stays on our servers.

Disconnect

Settings → Storage → Disconnect revokes the token. The "PratikYedek" folder remains in your OneDrive — delete it manually if you wish.

Troubleshooting

"401 InvalidAuthenticationToken" — token rotation failed; reconnect
"429 TooManyRequests" — Microsoft Graph throttling; PratikYedek retries with exponential backoff
MFA challenge — Microsoft sometimes requires reauthentication after a security event; just reconnect

Differences from Google Drive
