Emails on one account show up late
I have multiple email accounts but this one IMAP account has been problematic. Simply, new emails don't show up until either I rebuild the Inbox or wait anywhere from 10 minutes to several hours (they do appear in webmail and on my iPhone). After reconfirming that the settings are all correct, I've taken the following troubleshooting steps:
- I deleted the account from my Mac and re-added it, allowing it to repopulate from the IMAP server. Unfortunately this didn't help.
- I made a new user profile and added the account there. Here it worked better. This tells me that the problem is within my profile.
Since Apple moved control of Mail accounts into the Internet Accounts system prefs, I'm less clear on how to proceed to clear this up without affected my other email accounts (messages, iCloud, etc.). In the past I might have deleted my mail plist file and re-created those accounts. Is there anything I might try short of deleting the com.apple.internetaccounts plist file?
