No server available

Getting a lot of these messages today.

[IMAP] Cannot open folder “/Sent”. (NO Server Unavailable. 15) (various folders)

I can log into my account on Outlook and the server is working fine so is there an issue with eM Client?

I’m also seeing the same errors

SInce 2 days , me too I get a lot of these messages , in addition the color coding of the received mails in the different folders are again and again lost.

What is wrong and what is the solution ???

I also got these error messages, but it seems that the problem is not at the eM Client app, but rather at the Microsoft server side. I came into this conclusion because I have another PC with much older version of the eM Client and still the same error messages are appearing. I tried to disable the AirSync option from the account settings and also changed IMAP port to 993 and security policy to “Use TLS on special port” and now the errors seem to be gone.

thanks a lot, I tried your settings but it didn’t changed anything at all. I still get these error messages and the messgaes I marked by colours loose the markings and colours again and again
So the problem ist still existing

is there somebody from eMClient Support looking at the problem and looking for a solution ???
Please take care to find a solution !!!

Not sure if Microsoft has done something at the server side, but I haven’t seen the errors in a few days now even when using the original account settings.

I’m still seeing the same errors. I tried reinstalling an earlier version of emclient and that too is giving errors whereas before it was ok.
