COM ADD-IN ONLY
If the automatic update failed, there could be different reasons. Most often it is caused by a restrictive firewall or the company proxy.
Whitelist Update URL
If possible, you can ask to whitelist the updater URL in the firewall / proxy. The updater runs on Outlook startup and checks for new updates at:
https://api.yasoon.com/*
Update manually
You can also download the new version manually and install it on top - without uninstalling the old version.
Just install the new version as described here: Installation COM add-in
The Office Add-in is always up-to-date
