Hi
I can easily connect the outlook on pcs to my internal exchange server 2019 with both imap and mapi method.
but on mobile devices i encounter "timeout" and "can't reach server" problem !
I tried all possible way with android gmail and outlook and ios mail and outlook but from these only gmail and ios mail work with imap method!
the firewall on server is totally turned off and checked dns autodiscover and _autodiscover and i even scaned the open ports on server with same mobile devices and all corresponding port (25,143,443,993,587,465 ) are open!
and even set internal and external addresses of owa autodiscover ecp mapi imap the same but still gets timed out!!!
