Gmail accounts trouble sending emails

Problem with Sending Emails in New Outlook (Version 1.2024.625.600)

I've set up two email accounts in my New Outlook:
1. A personal Gmail account
2. A Google Workspace email account

Issue:
Sometimes, emails from these accounts fail to send and remain in the draft folder. This happens inconsistently, with no clear pattern. The problem occurs with both accounts and affects emails with and without attachments.

Workaround:
When emails fail to send in Outlook, I can successfully send them by:
1. Logging into the respective Gmail account through a web browser
2. Opening the email from the draft folder
3. Sending it from there without any issues

I'm unable to identify why this problem occurs in Outlook but not in the web interface. Can you help me troubleshoot this issue?
