I kept getting a message saying Please Upgrade the Office database. The options were "Upgrade" or "Quit Outlook". I kept selecting "Quit Outlook" all day and finally caved and selected "Upgrade". Now all of my email is gone. I've tried rebuilding the database to no avail.
I just started having this problem every time I delete an email in Outlook.  I don't recall making any changes to the settings, so I'm not sure how to fix this.  Whenever I delete an email, it immediately sends the email to the trash just as it should.  However, a few moments later once the folder syncs, another copy of the same deleted email will show up and mark itself as unread.  Basically, I will end up with duplicate deleted emails and one of them is always marked as unread.

I am using Gmail and use the "[Gmail]" folder as the IMAP root folder.  I also have it set to move deleted items to the Trash folder.  

Any ideas why this is occurring?  Thanks in advance!
The search function sometimes works, but other times it says 'No Results' when there should be a result and I have to locate the email manually. I never used to have this problem. It seems to be worse when the search item is a number rather than a word. Can anyone help please?
I archive email from my work Exchange to folders that are under the 'On My Computer' section of Mac Outlook, but I cannot find where to locate these actual folders on my hard-drive so I can then back them up
Cannot send emails in Outlook using office:mac 2011. I could 3 days ago. I can recieve them. I get an error message stating: operation on the server has timed out. I changed the port to 587 from 25 as suggested. If failed to help and now the message states authentificatin required. I called my provider and they used every pot combination possible to no avail. Help.
I have the basic version,word excel,powerpoint but need outlook2011 for the iMac 
We do not allow for Corporate emails to be downloaded to PCs/Macs outside of the building. This is the default for Windows/Outlook (i.e. you have to explicitly enable RPC/HTTP, Outlook Anywhere, etc to enable external Outlook clients). It appears that Outlook 2011/Mac circumvents these controls (presumably since it works through OWA) and allows external users to connect to and download local copies of Corporate emails.

I want to prohibit this behavior while still allowing internal Mac Outlook 2011 clients to connect.

It doesn't look like Outlook 2011 uses ActiveSync technologies like phones do so I don't think I can set up restrictions there.

Suggestions?
I'm running version 14.3.4. I think this may have happened after my last update.
When receiving emails, I normally flag emails that I need to respond to at a later date. I simply click on the flag to the right of the email and it toggles to a red flag. When I have completed my task, I click on the red flag and turn it into a green check mark, indicating to me that I have completed my task. I have flags that may be months old but still important to me.
Since yesterday, all of my flags are lost. I tried flagging emails but within minutes, the flags all toggle off.

why is this happening?
