Offering a number of improvements and fixes, Microsoft Office for Mac 2011 14.2.3 more importantly resolves a security vulnerability with folder permissions in certain Office for Mac 2011 14.2 versions, which could enable an attacker to run a malicious executable and take control of your Mac. Apart from the beefed-up security, the release also improves stability in Excel when dragging to move a PivotTable row or column, improves Full Screen View integration with Word, and fixes an issue with some SkyDrive folders displaying as zero-byte files. The update also addresses several IMAP issues in Outlook, resolving a problem where some configurations repeatedly displayed “Cannot create mailbox” errors, fixing duplication of email messages when connecting to Gmail using IMAP, and adding a setting to control the polling interval used with IMAP servers to avoid intermittent “Too many simultaneous connections” errors.
