Microsoft has released the Microsoft Office for Mac 2011 14.5.1 Update. (113.6 MB) Installation requires first installing the cumulative 14.1.0 (SP1) update if running an earlier version of Office for Mac 2011.
According to the new update’s description it addresses the Inbox Invisible bug on OS X Yosemite (10.10) systems introduced with the 14.5.0 update.
Four days after releasing the update as a download on its website Microsoft has yet to release the update via its AutoUpdate utility. Given the severity of the issue and the quick response (one week after releasing the 14.5.0 update), Microsoft may be slowly rolling out the new update as it vets it with customers. That’s unconfirmed.
Customers running Yosemite who haven’t yet updated to version 14.5.0 should update no further than 14.4.9 until Microsoft releases the 14.5.1 update via AutoUpdate. Customers who’ve already installed the 14.5.0 update and experienced their Main Window not opening should download and install the update or revert to Office for Mac 2011 14.4.9.
The update is available for immediate download.
