What to do
- Try Reconnect once in case the provider returned a temporary error.
- Confirm that Gmail, iCloud, or Yahoo is using a provider-generated app password—not the primary password. Microsoft must use the in-app personal-account sign-in.
- If the same message returns, choose Try another mailbox.
Why we need IMAP
Snapattic reads attachments over a private, direct IMAP connection to your computer. It is read-only: it can list and read messages, but never modify, move, flag, or delete them. Your photos and email content never leave your machine.
Work or school accounts
The release supports personal mailboxes only. Microsoft work/school accounts and custom domains are excluded, and provider policies can make IMAP unavailable. Snapattic cannot change that policy. See Account type blocked.
