I cannot replicate this issue on other operating systems, so either the file you have is corrupted or it is an issue with Mac OS. Please see if you can verify the hash of the file. The result of an SHA256 hash should be the following: SHA256: 9676ca02b32c15bf47bcf4295131d807a2729c2d1cddc53c4d40b57aa6c6d32b

You can acquire this hash directly through python with the following code:

with open("/Users/kashifiqbal/Documents/extract-msg-code-samples/strangeDate.msg", 'rb') as f:
    print(hashlib.sha256(f.read()).hexdigest())
