Good Morning,
99% that the problem may be in edgerouter.
If you remove edgerouter from the network, everything works a better a much more faster.
IMAP and POP it´s OK.
Looking at my dashboard I noticed a limit on bandwidth using only one computer on the network.
The limit that show in the dashboard is between 1, 1.5 and at most 2MB (up / down).
Send mails with attachments with size of 3MB can last about 1m to leave the mailbox. 10MB can reach up to 5m.
My connection is of 80/80Mbps (down/up)
I have installed edgerouters on multiple clients and all are in trouble.
My services (Office365 e Exchange) are on GoDaddy and Amazon
When you remove the edgerouter, the same email that takes almost 5m is sent almost instant.
Soon I will post my settings.
Please, I urgently request this case.
Thanks a lot.
