#609 Can't read shared calenders having permission "Limited Details" or "Availability Only"

[Herbert Meier]

Hey,
we are running an Exchange Server 2013 (I guess its version 15.0.x) and I'm having problems with reading calenders where I have only the permissions "Limited Details" or "Availability Only" (e.g. "Full Details" works perfectly). Attached is an excerpt of the davmail log. I hope its useful, if not I'm happy to provide more if someone can tell me what to try.

As the error states: ErrorFolderNotFound, I guess this is a server side issue : Exchange does not allow access to those folders over EWS.

You can check this in EWSEditor

Thanks for the response, I will check with EWSeditor. But how is e.g. https://github.com/Ericsson/exchangecalendar able to access these calendars?

Edit: you are right, EWSeditor is also not able to access the calendar for "Limited Details" or "Availability Only"

Thanks for your feedback, can you get a request log for the Ericsson client to understand the difference ?

[Herbert Meier]

In Thunderbird (with the above mentioned plugin installed), I enabled in the genereal settings (Edit-> Preferences -> Exchange(EWS)-> Communication with exchange server ) the logging. It contains a lot of private information and HTTP headers but unfortunately, I'm not an expert so I don't know which part could be interesting for you.
May I kindly ask you give it a try and check the logs with your own server?

If the data provided by the log is not sufficient, please tell me and I will try to intercept some of the SSL traffic using self-signed certificates and wireshark etc.

Thanks in advance and I'm looking forward to your reply.

I don't need any private info, just the way it gets the target folderId:

• DavMail sends a GetFolder request to get <t:DistinguishedFolderId Id="calendar"> (default calendar)
• What kind of GetFolder request do you see in your other client ?

I tried to extract some (hopefully relevant) information from the thunderbird logs. Please see here: https://gist.githubusercontent.com/bonanza123/2ab6aefbe1d6aa7ef12e/raw/048f52e017831eca309091cf02ca5b37d4d40609/davmail

is this was you are looking for?
