Office upgrade to 14.5.0 as of May 12, 2015

Additional comment:

it seems to be related with interface (folders) layout. I have two accounts: Exchange and IMAP. Plus number of offline folders. Noticed that after some folders are expanded (folder tree expanded) and maybe after folder change - it starts to behave badly (close, then next startup does not show any windows, so need to redo recovery steps above).

However that does not happen 100%. When collapsing the tree before closing, Outlook seems can reopen normally.

I had already rebuilt my identity (which did not resolve the problem), and then followed these instructions, which DID resolve the problem.

I have the same problem...just installed, now will recover from backup hopefully.

Thank you, mkubilius, this worked perfectly for me!

Thanks @mkubilius - that worked!

This is the simple fix as tssr described at 2:22 AM (you should be sleeping at this hour).

If you have a time machine back up:

Delete Microsoft Office 2011 from you applications, and then drag over the Microsoft Office 2011 Application from your most recent Time Machine back-up.

Thanks, tssr

Thanks this worked

Thats one helpful BFH. 🙂

EDIT: The quoted text didn't come through. I meant if MS recommends uninstall/reinstall, it's a BFH, considering all the garbage their installer litters your computer with.

I've used with success the technique of using defaults to remove the preferences and killing the cfprefsd processes. When launching Outlook afterwards I'm prompted to either setup a new mail account or import. I choose the new account option. The resulting preferences pane that is opened is pre-populated with my original account details. Good news there. I simply accept it and close the preferences window.

Now comes the task of returning the various preferences and display of the windows to how I like it. Done.

I quit Outlook.

I relaunch and the missing window problem has returned.

After trial and error I've found that the problem occurs when I expand the Exchange mailbox subfolders and, importantly, quit with them expanded.

As long as I ensure that there are no expanded mailbox subfolders the application can be used.

I hope this annoying bug is addressed very very soon.

Same issue - works ok when tree closed. Have to fix it again when open. Annoying. Thanks for your posts!

This works great for me - but as some have mentioned, when you Quit the App - the problem returns.

What I found is if I have the SMART FOLDERS expanded the issue returns - if I leave them closed , I am able to work as expected - even if I have other folders expanded.

I am using standard POP on my own mail server and NOT Exchange.

Hope this helps?

I contacted Microsoft and got no help. I was told its a unique problem to me and they asked for tech support money - $99 for one time $149 for year.

That's great! How about your system information like OS version, year model, RAM?
