Using the New Outlook for Mac for personal email and calendar
Hello dan harper,
Since the other Gmail account works normally, this seems specific to the connection between Outlook and the affected account.
Try removing Outlook’s authorization directly from Google to refresh he Google authorization token:
- Close Outlook.
- Open your Google Account in a browser.
- Go to Security > Your connections to third-party apps and services.
- Select Microsoft apps & services, then remove its access.
- Reopen Outlook, add the Gmail account again, and approve every requested mail permission.
If the issue continues, use Gmail on the web as a temporary workaround and contact Outlook support for further assistance: In Outlook, select Help > Contact Support, then describe the Gmail synchronization issue and start the conversation.
Since this is a user-to-user forum, we cannot inspect the account’s server-side connection, but Outlook Support may be able to check why this specific mailbox is not syncing.
Thnak you so much for your patience!
