I just got my wife a new PC. No complaints otherwise, but I installed a new version of Office, including Outlook (Microsoft Office Professional Plus 2016/Outlook 2016 MSO 64-bit). It is running Windows 10.
She works quite a bit from home and uses Outlook for her work mail. I copied all the email settings from her old Outlook to this new version. She called her work's ISP and they got her all of her old messages and had her set up an .ost file. I've used .pst files before, but never ost (she had a .pst on her old PC). Outlook worked fine on her old PC with an older version of Outlook, but it is incredibly slow with this new version.
I'm a software engineer, so I can usually fix these issues pretty quickly, but this one has me beat. Symptoms:
- Sending a message takes a minute or more
- An item sent can take 15 minutes or more for her to receive
- At the bottom of the Outlook window, a "working" bar appears saying "Synchronizing 'Inbox'" (other folders appear sometimes, like 'Sent items'). It never goes away.
- A Send/Receive bar at the bottom (next to "working" bar) goes about halfway, and never completes.
I tested the email account settings when setting it up, and they completed fine, but it still took 10 minutes or so to receive the test email.
I know problems like this are hard to diagnose and fix, but I'd appreciate it if someone could at least give me some things to try. To answer the obvious, yes, I did shutdown and reboot (several times).
