Installed pilot of webmail pro. Admin panel works. During login as a user account I small warning messages during login.

Internal Server Error. Please, contact your system administrator in order to report the problem

Server is Imap on Exchange 2010.

I enabled Debugging logs and see this:

The IMAP4 server does not support SORT capability required to perform sorted search.
MailBee.ImapMail.MessageIndexCollection a(Boolean, System.String, System.String, System.String)
[Stack Trace]
   at kr.a(Boolean A_0, String A_1, String A_2, String A_3)
   at ab.a(Boolean A_0, Boolean A_1, String A_2, String A_3, String A_4)
   at WebMail.ImapStorage.LoadMessageHeaders(String messageIndexSet, Boolean indexAsUid, Folder fld)
[Method]: a
[Line, Column]: [0, 0]

Any Ideas?

Indeed, WebMail Pro ASP.NET requires mailserver to be able to return mails in sorted order. If that's not the case with particular server you use, you can try modifying App_Code/MailStorageImap.cs file, replacing the line:

MessageIndexCollection indexColl = _imapObj.SortedSearch(indexAsUid, messageIndexSet, null, "REVERSE ARRIVAL");


MessageIndexCollection indexColl = _imapObj.Search(indexAsUid, messageIndexSet, null);

Note that while files under App_Code are usually recompiled automatically, you may need to run compile.bat file found in root WebMail directory to apply changes.
