IEWSClient.GetMailboxInfo(string mailbox) throws exception

Hi,

We have recently updated from Aspose.Email v. 5.0.0.0 to v. 5.7.0.0, and since then we are getting an exception when calling the method IEWSClient.GetMailboxInfo(string mailbox).

It is working when we are using the older version.

Here is the exception:

ExchangeException: Mailbox information can not be read.

Folder Id: 'contacts'; Message: The specified folder could not be found in the store.

Folder Id: 'deleteditems'; Message: The specified object was not found in the store.

Folder Id: 'drafts'; Message: The specified folder could not be found in the store.

Folder Id: 'journal'; Message: The specified folder could not be found in the store.

Folder Id: 'notes'; Message: The specified folder could not be found in the store.

Folder Id: 'sentitems'; Message: The specified object was not found in the store.

Folder Id: 'junkemail'; Message: The specified folder could not be found in the store.

at _ ._(String _, _ & _, Int64& _)

at _ .GetMailboxInfo(String _)

What could be the problem?

I should probably add that it only seems to be a problem on mailboxes accessed via a certain set of user credentials. Mailboxes accessed with another users credentials are working.


/Andreas

Hi Andreas,

Thank you for writing to Aspose Support team.

I tried this scenario with Exchange Server accounts on Office365 server and two test accounts. At first, I was able to reproduce this issue as you mentioned. After investigation, it was found that UserOne didn’t have enough permission to get Mailbox information of UserTwo, as there were no delegations implemented.

After this, UserOne was allowed permission to access UserTwo mailbox and the error vanished. Thus, it seems that there is some permissions issue at your end. We have also tested this case on Exchange Server 2010 and it works fine with mailbox delegation assigned.

Please try the following code at your end and let us know your feedback. The test accounts are actual on Office365 Server and have been provided for testing purpose.

Sample Code:


IEWSClient client = /*GetAsposeEWSClient1();*/ EWSClient.GetEWSClient("https://outlook.office365.com/ews/exchange.asmx", "UserOne@ASE1985.onmicrosoft.com", "Aspose1234");

// Get Exchange mailbox info of other email account

ExchangeMailboxInfo mailboxInfo = client.GetMailboxInfo("UserTwo@ASE1985.onmicrosoft.com");

Hi Kashif,

Thanks for your reply.

As I expected the sample code you provided worked. But as do all accounts in our dev environment and the majority of our customers accounts. At first, I also expected it was a permission issue, and maybe it is, however, it really bugs me out that everything is working fine if we roll back to the older Aspose.Email dll.


Are you able to derive anything specific from the stacktrace?

/Andreas

Hi Andreas,

As mentioned earlier, we could reproduce the exact problem at our end when the accounts didn’t have permission to be accessible from the other account. Thus, we consider this the prime reason for the issue you faced.

Can you please us with credentials of a couple of test accounts at your end that we can use to reproduce the problem at our end? We’ll try it with the latest as well as the API’s earlier versions and share our feedback with you for your assistance.

Hi Aspose,



The problem did not exist in Aspose.Email.dll version 5.2. But in version 5.3 an up we get the error you can see in the attach file.



I used this code:



IEWSClient client = EWSClient.GetEWSClient(“https://outlook.office365.com/ews/exchange.asmx”, “lars@nexcom.dk”, “xxxxx”);

ExchangeMailboxInfo mailboxInfo = client.GetMailboxInfo(“etray@nexcom.dk”);



The real password has been replaced with “xxxxx”, since I do not want to share my private Outlook password :slight_smile:



With regards

Hi Lars,


We tested this issue with our test accounts on Office 365 and could not face any error after granting permissions of one user account to another user account. Since Office 365 provides its users to create trial accounts for testing the whole functionality, we request you to please create two test accounts and help us reproduce the problem using these accounts. You can:

  1. Create two test accounts on Office 365 server
  2. Grant permissions of mailbox access of one account to the other
  3. Share the test account credentials with us
We shall test this issue with your test accounts and share our feedback with you.

Hi Aspose,

I send a mail to Muhammad.Waqas with my Outlook password to Offcie 365.

Please be aware that we have this problem on several hundred mailboxes at client installations.

You need to address this issue, since we are forced to upgrade to Aspose.Mail 5.7, because of the Offcie365 error you fixed for weeks ago.

With regards
Lars Bøndergaard

Hi Lars,

Thank you for your additional feedback.

Upon further testing, we were already able to reproduce this issue at our end and it is logged as EMAILNET-34992 in our issue tracking system. Our product team will investigate the issue and include the fix in the upcoming version. We’ll notify you here once there is some information available in this regard.

Hi Aspose,

It is very frustrating that your haven’t fixed this issue in Email.net 5.9. We are currently traped on Email.net 5.2, which do not support Office365, because of an error your fixed in Email.net 5.7.

Therefore, it’s very important for Nexcom to get a new stable Email.net version we can use. Our business depend on Aspose, delivering the right quality.

With regard
Lars Bondergaard

Hi Lars,

We are very sorry for the inconvenience you have faced.

Can you please try this with the latest version of the API and share your feedback with us? We have discussed the matter with our product team and have come to know that it has been fixed in the latest version. It was just that the notification was missed to update you about the status of this issue. We tried to reproduce it at our end but it seems you have changed the credentials for the account at your end. Please try it with this latest version of the API and share your feedback with us.

Hi Lars,

Can you please confirm to us if the latest version has solved your problem or not? Our product team is looking forward to provide a hotfix in case your issue is not resolved. Please share your test credentials if the issue is not resolved yet at your earliest. We are looking forward to assist you further and awaiting your reply.

Hi again,

Great, it works with Aspose-Email 5.9.
Thanks for your help. We are happy :slight_smile:

/Lars

Hi Lars,


Thank you for the feedback and we are glad to know that your issue is resolved. Feel free to write us back for any other query.
