SERVER PERFORMANCE DECREASED WHEN INDEXING ON
When the full-text search is already running or turned on during the server upgrade/installation, your server could face a temporary decrease in its performance due to the indexation of documents. This can take several hours depending on the volume of your data.
INSTANT MESSAGING DOESN'T WORK
When the Digest-MD5 is disabled in the remote console - System - Advanced - Digest-MD5 then IM doesn't work and shows offline status.
The second issue regarding IM is when the user has in the remote console - Domains & Accounts - Management - Domain - User - for username this format: firstname.lastname@example.org. The workaround is to set up only "user" in the username column without a domain.
TEAMCHAT AND CONTACTS DOESN'T WORK
This is caused by case sensitive MySQL database. IW expect to work with case insensitive database. Below you will find an article on how to change MySQL case sensitive DB to MySQL case insensitive.
TEST CONNECTION ON WEB DOCUMENTS DOESN'T WORK
Unfortunately, this is known as BUG but it doesn't have an effect on the WebDocuments function.
ISSUE WITH OTHER ACCOUNTS IN WEBMAIL
If you have lost added IMAP account in the webmail during the upgrade and you cannot add a new then go to the file system - to the mailbox of the affected user - ~webmail and delete accounts.xml. In this file are specified other accounts. After this, you will be able to add an IMAP account again.
ISSUE WITH OUTLOOK SYNC LICENSE
Outlook Sync version 13.0 has an issue with the reference ID of OSync. If you are receiving error windows regarding activating/deactivating the license then do a downgrade to 12.3.
ISSUE WITH IMAP IN IWDC
Change in remote console - File - API - c _system_services_imapsearch_maxresults from "10000" on "0" (unlimited).
After that, you need in every folder which has more than 10k items delete or rename file "flags.dat" to start synchronization again. After restarting POP3 it should be OK
MISSING TABLES IN GROUPWARE DB
alter table event add `EvnDocInvite` int(11) DEFAULT NULL;
alter table event add `EvnDocExpire` int(11) DEFAULT NULL;
alter table event add `EvnDocRights` int(11) DEFAULT NULL;
alter table event add `EvnDocPass` varchar(255) DEFAULT NULL;
alter table onlinedocumentediting add `OdeDocKey` varchar(255);
alter table onlinedocumentediting add `OdeAttName` varchar(255);
ISSUE WITH LOGGING TO WEBCLIENT
Remove content of /opt/icewarp/html/webmail/client/skins/banner/templates/ except template.xml
In the mailbox of affected user - ~webmail - settings.xml remove value <skin>banner</skin>
Go to the webadmin and reset the webclient skin to default.
If you cannot reach WebDAV and you are receiving "Not found" error then you need to change the path to CalDAV/CardDAV from:
ISSUE WITH SENDING MAIL THROUGH WEBMAIL
If you are sending mail from webmail and you are receiving "PHPMAILER" error.
This happens for accounts that have mailbox type set to "POP3". These accounts won't be able to send mail through webmail until switched mailbox type to "POP3&IMAP" or "IMAP" in administration.
OUTLOOK REDEMPTION ERROR
When you will receive this error in OSync:
Access violation at address 0000000000B71BDF in module 'Redemption64.dll'. Read of address 0000000000000000 at Redemption.RDOFolderClass.get_Folders()
The only possible workaround is to downgrade to version 22.214.171.124.
ISSUE WITH HIGH CPU/MEM PERFORMANCE
If you have an issue with performance on the server then it can be caused by YODA and YODA-SCAN services. Unfortunately, version Deep Castle Gen 1 doesn't have the option to manage how much resources it will take. Once indexing of the whole /mail/ folder will end the performance will be lower.
High CPU/MEM can also cause off smallfilles cache. Article about smallfiles cache you can find here:
ISSUE WITH SYSTEM BACKUP IN REMOTE CONSOLE
In DC Gen 1 backup tool doesn't work correctly. There are several issues reported regarding the internal backup. We are recommending to setup backup using the following script. Then you can put the script to Task & Events in the remote console - System - Tools - Task & Events (for example).
It is necessary to modify the script for the actual environment.
In case you are using SQLite, you can backup only the SQLite files on the file system (using robocopy or rsync).
