How do I keep Outlook for Mac 2011 from dropping email (gmail and gvtc below) passwords out of my Keychain?

I run Keychain First Aid and it's fixed for less than a day.  Then I run Verify again and get the following:

Verification started
Checking keychain configuration for office2 (user ID=501)
Home directory is /Users/office2
Checked login keychain
Checked password for ~/Library/Keychains/login.keychain
Checked settings for ~/Library/Keychains/login.keychain
Checked default keychain
Checked contents of ~/Library/Keychains/login.keychain

Item “imap.gmail.com” has unspecified value for port attribute
Item “imap.gvtc.com” has unspecified value for port attribute

Problems were found; you should choose the Repair option to fix them
Verification failed
