stuck at autodiscover

Hello Thomas,

what can I do to solve this?

2020-02-18 15:09:41,108 [1] ERROR RemovePrivateFlag.Program [(null)] - Connection to mailbox failed

Did you used the parameter “-allowredirection”?

[exentim]

Thanks for the quick response. No I did not. I tried it now with the following result:
2020-02-18 16:30:23,217 [1] ERROR RemovePrivateFlag.Program [(null)] - Connection to mailbox failed

In EWSEditor Autodiscover works.
Maybe I have to use impersonation param. How to use the impersonation param correctly?

[exentim]

Thats what I try:
RemovePrivateFlag.exe -mailbox tim.surname@domain.de -logonly -foldername "Posteingang" -al
lowredirection -user ycx2459 -impersonate

[kecarallofas]

The user need to be an SMTP-address. If you use “-user” you need also pass with the option “-password” the password for the user account which should impersonate.

If you don’t pass the “-user” option the program will be use the current credentials of your session (from the command line or the powershell session).

[exentim]

Sorry to disturb again :)
it is still not working, trying this:

RemovePrivateFlag.exe -mailbox tim.surname@domain.de -logonly -foldername "Posteingang" -allowredirection -user tim.surname@domain.de -password PasswordX -impersonate

[exentim]

can this help? https://stackoverflow.com/questions/11477255/read-email-using-exchange-web-services

Maybe adding the version is needed like in EWSEditor?
var service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);

The problem lies in line 313 accordng to output above.
service.AutodiscoverUrl(MailboxID,RedirectionCallback);
// AutodiscoverUrl(String, AutodiscoverRedirectionUrlValidationCallback)

What does your comment mean for the second part?

Please help :)

[kecarallofas]

I've tested the version now against O365 and an Exchange 2016. Here it works flawlessly. Against an Exchange 2019 i receive the same error message. Requesting the version with the service creation doesn't remove the error. Against which Exchange version to you running the tool?

[kecarallofas]

@exentim Could you please try the following build? This is working in my test lab. Requirements for .NET have changed (now 4.8).
Release.zip

[exentim]

Hello,
I tried your build.
We have ExchangeVersion.Exchange2013_SP1
