Around every 15 minutes my outlook client will get stuck updating some kind of folder and not allow emails to send\receive. Closing outlook and reopening will send the email in my outbox and new emails come in. Rinse and repeat all day.
- I've gotten rid of the email profile.
- Uninstalled Outlook 2016 and tried Outlook 2019 (same problem) and now back on Outlook 2016.
- Disabled all add-ons except Microsoft Exchange Add-in.
- Uninstalled my anti-virus.
- Disabling Windows Firewall.
