Outlook New E-mail Icon doesn't show in Systray (Notification Area)

This is resolved. I called IT Support yesterday (after 3 days) and she said "You know, I don't think I've gotten notifications either lately ..."

But ...

I had previously disabled cached mode for E-mail to try to fix an error with searching .pst files. Another support tech said cached mode was actually recommended, so I re-enabled it. Once I re-enabled it and re-started Outlook, it said "preparing for first use", but then my notifications started working again.

I'm not sure if they stopped working b/c of the security updates or if disabling cached mode caused the problem. I somewhat suspect it is just that switching on and off cached mode cleared some memory setting or registry value, but at least the issue is resolved.

Sounds like it was turning on cache mode did it. Glad you got it fixed. :)
