Each mailbox will travel at the rate of the slowest network. i.e. If the source has a smaller pipe than the destination, we will max out at the source speed and vice versa. … Continue reading

The error messages that you see are either low level errors that are generated (like connection timeout, or host not reachable) or higher level errors (like system error, cannot be fetched). Usually the higher level errors are … Continue reading

Here’s a tip that could decrease your migration by an hour or more on average. By default, we search the destination server if we have migrated the item before creating it. We do this to ensure that in all cases we will never duplicate items in a mailbox. Well, if this is the first time … Continue reading
