Outlook for Mac Does Not Work on OS X 10.10 (Yosemite Public Beta)

My thanks to all who have contributed to this thread, since between one clue and another I have been successful in finally getting Outlook to behave normally. Back to its happy old self -- in Yosemite.

Stuart - although our issues are different I'm hoping this may resolve for you as well:

• Delete the outlook.plist file 
• Launch Outlook with the Option key held down; this brings up the Database Rebuild app that allows you to establish a new identify (in addition to the "old" misbehaving version that is listed in the box). I created a new identity, used the Settings button to make it the Default identity (it turns bold)  and closed out of the app.
• Launched Outlook. The Main Window appeared - yay! This is what I had not been able to see before. Then go into prefs>accounts and create a new Exchange account (I'm on a corporate network as well). The new account instantly downloaded all mail residing on the server. Calendar items all intact, Contacts all there as well. the only thing missing was 6 years of stored emails in multiple folders. 
• Closed out of Outlook. Relaunched with Option key. Brought up the Database Rebuild app. Rebuilt my old Identity folder (this process generous a clone copy of itself, self-titled "Backup"). After the rebuild I used the settings button again to establish my rebuilt folder as the Default identity. Quit out of the app.
• Relaunched Outlook. Main Window appears. Went into Prefs panel, General, and untagged the "Hide on my computer folders" box. Closed Prefs and all my archive folders reappeared. Years worth of emails once again on view and available. Life is good. Now I can enjoy Yosemite.

Cheers, Bruce

Hi, Clinton

My experience has been very similar to Bruce's experience. Last Friday I had an operational Outlook application under Mavericks that I use at work. I installed Yosemite (over the top of Mavericks) on the weekend. Came back to work on Monday and have since found it impossible to get a connection to the Exchange server.

I don't experience the "missing main window" problem. I just can't get a connection to the server.

I get continuous popups of the following dialog.

Checking "Always use my response for this server" appears to have no effect: the dialog box comes back. If I try using curl on the URL listed in the dialog box I get a "600" error, but then so does my colleague running Maverick - but his Outlook works.

I have tried setting up the account in Apple Mail (by the way, I agree with you about Apple Mail), but this does not work either, with very little (none) feedback.

I have no idea what to do now. Outlook doesn't work: web access to Outlook does work (but is very inconvenient). I'm not sure who to "blame" here (apart from myself for not reading this forum before upgrading to Yosemite ;)). Though, I suspect it's Microsoft's problem for not keeping up with changes in the new release of Mac OS X - I mean Yosemite was only in public beta for how long? months?.

I have tried "delete .plist, move identity files, reboot, ..." recommendations: didn't work. I've tried the "kill the database daemon" recommendation: didn't work.

Outlook is the only application of the many I have on this machine that doesn't work.

This is very frustrating.

I installed Yosemite on a MacBook Pro and everything worked fine. Then tried an install on an older MacPro.  In this case, the Ethernet connection was lost and had to be re-entered in System Preferences/Network. Also, one can no longer perform searches in Outlook. Strange because searches work fine on the laptop. Will notify Apple of these glitches.

Dan NB,

Mail is a bad product - I frequent the Apple Community Support forums and if there's one application that folks are going to have problems with, it's Apple's Mail. The problem with Outlook and Yosemite has been solved - by Apple - and you no longer have to jump through any hoops to get it up and running at this point.

I don't know what type you're having with Time Machine restores - that Office always asks for the activation key? That's true of a number of applications and, to my mind, is a great way to avoid pirating of the software.

Even if you do decide to give up Outlook - find something else to run other than Mail (Thunderbird, for example) - but there's no good reason that I can see to give up Outlook (and, yes, I run it both on OS X and Windows 7 Pro).

Good luck,

Clinton

I see this thread needed on Oct 13. Today is Oct 21. I just downloaded Apple's final release version of Yosemite. And Outlook Main Window won't open (searching for solution brought me to this thread). From what I read above it seems that Beta 3 of Yosemite resolved the issue for users on tags thread. These users thereby suggested Apple had "fixed" the problem. Meanwhile another thread elsewhere on the web says taht running MS Office Updater 14.4.5 resolved the issue for them, and thereby pointed to MS as having been the ones who "fixed" the problem. Regardless, I've got the wide release of Yosemite installed, I ran MS Office Updater 14.4.5 (twice), I've rebooted, and I still have the missing Main Window problem. I'm stymied. MS Word, Excel and Powerpoint work fine. no issues. Only Outlook and the missing Main Window. Argh!!

Bruce,

I've no idea whatsoever why you're having the Main Window problem in Outlook using the release of Yosemite. My same problem was 'fixed' with Developer Release 6, far before the update to 14.4.5. You need to file a Bug Report with Apple (I really do think that they were to blame for the problem, as it was a known bug and when I filed a Bug Report, it was listed as a duplicate bug reported).

Try -> https://idmsa.apple.com/IDMSWebAuth/login.html?appIdKey=77e2a60d4bdfa6b7311c854a56505800be3c24e3a27a670098ff61b69fc5214b&sslEnabled=true&rv=3 - I THINK that you'll be able to use a standard Apple ID to access the page (although it's listed as being for developers).

I haven't heard of any having this problem with the release version of Yosemite and cannot offer any help. Maybe someone will come along shortly.

Good luck,

Clinton
