Hi,
The QR code contains a string formatted according to the otpauth uri format.
One of the format rules is:

The issuer prefix and account name should be separated by a literal or url-encoded colon, and optional spaces may precede the account name. Neither issuer nor account name may themselves contain a colon

Last time this issue was reported (see #234) it shows that Microsoft uses this colon to identify the company name when the 2FA protects a professional account:

Microsoft:CompanyName:[email protected]

Microsoft does not respect the otpauth format, it's why it's rejected by 2FAuth.

Here is a workaround:

• Decode your QR code here: https://joohansson.github.io/offline-qr/src/qr-reader.html
  (This page will decode the QR code without sending any data on the network)
• Copy the Result string
• Open 2FAuth, click the New button, then Import
• Paste the string into the Direct Input textarea
• Before submitting the string, replace the colon that separate the company name from your account id with any string
• Click Submit
