1. Text Encoding and Formatting:
Sometimes, issues with how text is encoded or formatted can lead to unexpected reformatting or jumbling of content within emails. This can be especially noticeable when pasting text from different sources or when using special characters.
2. Compatibility Settings:
Depending on the email client you're using, there may be compatibility settings that affect how emails are displayed and edited. It could be worth reviewing these settings to see if they are contributing to the issue.
3. Rebuild Mailbox:
Rebuilding the mailbox, as you've already tried, is a good first step. However, you might also consider resetting Mail's preferences to default to rule out any specific setting causing these issues.
Potential Solutions:
1. Plain Text Mode:
Consider composing your emails in plain text mode, especially for critical or official correspondences. This can help reduce the likelihood of unexpected text formatting issues, since plain text doesn't carry any formatting information to interfere with the message content.
2. Update Mail App:
Make sure your Mail app is up to date. Software updates often include bug fixes and performance improvements that could address unexpected behavior within the application.
3. Alternative Email Client:
In the short term, while you're troubleshooting, you might consider using an alternative email client to see if the issue persists. There are several third-party email clients that provide additional features and might offer a more stable text editing experience.
4. Copy Paste Method:
When copying and pasting text into your emails, try using the "Paste and Match Style" option, if available. This can help ensure that any copied text doesn't carry over unwanted formatting or encoding issues.
5. Contact Apple Support:
If the issue continues to persist despite these efforts, and especially if it appears to be a system-wide issue rather than being specific to a single email account, reaching out to Apple Support could provide valuable insights on troubleshooting and potential fixes related to the Mail app on macOS 14.3.
I hope these suggestions help iron out those pesky formatting glitches in your emails!
