When migrating mailboxes with Groupwise Migrator for Exchange the application may hang on large mailboxes. In the log files you may see the following:
WARNING: [7510-21-31-00001D57] Unable to count mail messages in folder 'Mailbox'
 Folder contains more than 8191 messages.
Groupwise clients have a bug in the API that limits the folder count to 8191 messages. By default the program will try to count messages by folder. If there are more than 8191 messages then you may receive the warning above or the application may just hang when migrating mailboxes with large amounts of messages.
Input the following parameters in the gwmigapp.ini file found in the program installation directory:
- Add the following line under the [GroupWise] section:
- Save and close gwmigapp.ini.
- Run GroupWise Migrator for Exchange again.
This will force the application to not count the messages by folder but just count all the messages in total which will result in working around the Groupwise API bug.
