I have added a second mailbox to my outlook. It will update when I start in the morning but last email will be like 9 am & will not update again unless it wants to. I have reconnected, shut down outlook, & can not get it to work. On my phone it works fine but on the pc it is like it has a option to check every 8 hours & will not check any other time.

The root of the problem may be that the second account has a large number of folders >500 will cause a problem with the OST file, it cannot handle more then 500 folders (in all accounts in this current profile) and this is why turning off cached mode may help. Removing this 2nd account may also correct this issue. It is a known limitation within the outlook client. Be aware that not running in cached mode may present performance issue if the mailbox is large or connected over a slow connection

I am having trouble with my email not syncing to outlook. I tried going to Account Settings/Account Settings/selecting the email file and then clicking change. The box for "use Cached Exchange Mode to download email to an Outlook data file is greyed out so I cannot uncheck it. Any other suggestions?
Outlook was working before. I had to totally restore and load all of the Office 365 programs back on. Ever since then, It has quit working. Also, I only have an .ost file. There is no .pst file. My old .pst is backed up on an external drive. Do I need to save on my PC and link back to outlook? If so, I don't know how to do that.

@options38 I am having the same issue. Outlook was working fine for months, with no issues and now its not updating my emails. Ive tried repairing both the accounts that I use, which did work for a bit, however its no longer working. I assume it was an update to outlook thats just broken? Every time I launch outlook i need to repair the accounts.

My solution might be too simple for the problems mentioned. However, here is what I did.
1. Went to Start Box and entered Task Manager
2. Selected Task Manager app shown.
3. Selected Outlook from the running apps shown
4. Entered Quit Outlook
5. Restarted Outlook
That fixed my problem. I think it occurred from emails being open with attachments never being closed.
