Hi Team,
I am migration mailboxes from domino to O365. I am now migrating a mailbox which is around 20 GB in size in domino. It has around 76000 mail items. I am using admin pooling utility while migrating mailbox. The mailbox migration starts properly. It first migrates all contacts (around 1663 items) and then all appointments and tasks (Around 7000 items) and starts migrating mail items. It migrates 397 mail items and then migrations stucks for some time and restarts again from 0%. This has happened for 4 times. Please help me resolve this. I see the error in the log files as mapi retries being exceeded.
Please Help.
