Hi,

I am using Oauth Proxy Server with Axigen, configured 4 accounts (all Office 365). However, got one account having issues and receiving duplicate emails.

After remove that user from Axigen and add back (re-authenticate the Oauth) the issues gone. But after few days, the issues come back again.

Any ideas to fix it? Thanks

This is unusual, but I'm afraid it is a client issue rather than anything to do with the proxy.

(The standard version of the proxy could not do anything to cause this, because it removes itself after authentication; the plugins branch could potentially do this via a misconfigured plugin, but I'm assuming that you're not doing that.)

Hi Simon,

Thank you for the feedback. Will troubleshoot the client instead.
