Troubleshooting
Windows SmartScreen says “Windows protected your PC”
Section titled “Windows SmartScreen says “Windows protected your PC””- Cause: release signing with Microsoft is still in progress, so SmartScreen doesn’t know MailCraft yet.
- Fix: check your download, then click More info and Run anyway. See Windows SmartScreen warning.
macOS says it can’t check MailCraft
Section titled “macOS says it can’t check MailCraft”- Cause: macOS builds are not notarized yet.
- Fix: open System Settings › Privacy & Security and click Open Anyway.
“Need admin approval” when signing in with Microsoft
Section titled ““Need admin approval” when signing in with Microsoft”- Cause: your organisation lets only an administrator approve a new program.
- Fix: MailCraft explains what to do while Microsoft’s page is still open. An administrator approves MailCraft once. Anyone else can copy a short message to send to their administrator. After approval, sign in again.
Google sign-in shows a warning or is refused
Section titled “Google sign-in shows a warning or is refused”- Cause: Google’s OAuth verification of MailCraft is still in progress. Until it finishes, Google may warn that it hasn’t verified the app, or let only approved testers sign in.
- Fix: add the account with a Google app password instead. A Google Workspace administrator may also need to allow MailCraft for the organisation.
The browser version can’t connect to my mail server
Section titled “The browser version can’t connect to my mail server”- Cause: browsers can’t open the connections IMAP and SMTP need. The browser build reaches only JMAP servers, read only for now.
- Fix: use the desktop app, or bring mail in with File › Import.
Linux asks me to sign in again after a restart
Section titled “Linux asks me to sign in again after a restart”MailCraft keeps sign-ins in the desktop’s Secret Service (GNOME Keyring or KWallet). Make sure one of them is running and unlocked. Remembering sign-ins across a restart on Linux isn’t fully proven yet.
Something Outlook does is missing
Section titled “Something Outlook does is missing”MailCraft doesn’t have every Outlook feature yet. Printing and .ost, .msg and .olm files are not supported. The full list is in Where MailCraft falls short.
