MDaemon may have automatically created crash dump., If it did, you find them in the MDaemon\Dumps directory, just put them in a zip file and upload them to us.
If dump files were not automatically created, please following the instructions in this article to collect crash dumps:
It looks like the crash is occurring when attempting to generate daily quota reports. If you turn off the daily quota reports, does the crash go away? Accounts / Account Settings / Other / Quotas, uncheck the box for Send daily quota reports to domain and global administrators.
I will try to change this but when launching the GUI I have a couple if seconds before an error message appear and the gui close. Is there a way to change this in a config file ?
Is the MDaemon service crashing or just the configuration session? The easy way to tell is just to see if there is still an MDaemon.exe process running after the crash.
Can you login via Remote Administration and make the change?
If not, you can edit the MDaemon.ini file and set the following in the [Special] section
Is there a folder in the a.jacobs mailbox called \KAi.imap\? If you move that folder and everything under it out of the mailbox path are you able to start MDaemon?
I have used Mdaemon for more than a decade and it's only the second 'big' issue that I have had.
But I must say since I upgraded to 23, I have issues with ActiveSync clients (a tickect has already been opened about couple of weeks ago) and IMAP, OC seems less responsive.
I will try to move Mdaemon to a new server. Can you provide the full procedure for such a migration ?
