Outlook 2025 Gmail Calendar Sync Issues. Outlook doesn't always close properly when you have an imap account in your profile and this can cause outlook to have sync issues. If you enter appointments into google calendar, there's a way to sync that data to outlook.
You can also try resetting the old shareable link to share new link. If outlook isn’t syncing emails, ensure your internet connection is working, turn off the app’s offline mode, manually sync your email folders, change your email.
