issue with active sync?

killmasta93

Hi guys, I was wondering if by default the active sync is disabled? Currently i have configured NGINX reverse proxy
https://pastebin.com/eefYckxX but cant seem on the mobile device to find the exchange server just keeps showing imap to configure, whats even odd is that on my test environment it works fine the only difference is that the test server i have version mail cow 2023-03

Thank you

DNS properly set up? Did you try to manually configure the client for ActiveSync?
ActiveSync is enabled by default.

Thanks for the reply, yeah it seemed that the CNAME was pointing to the A record that was not pointing to the mail, got that working thank you again,
Just out of curiosity, whats the recommended specs for the host to have if to say around 60 users using active sync?

it is per device, not users. A user can have multiple devices or none using ActiveSync.
You probably need more workers, which affects RAM and a little bit CPU:

It depends on the usage pattern, mailbox size etc. My guess would be 8 GB RAM and 4 vCPU. But could easily be more.

I don’t know, most of this log entries I have also, nothing to be concerned about.
For me its working with Outlook 2021.
Maybe an issue with your firewall/reverse proxy/public/private/NAT addresses
