Office 365 - Client performance during and after account migration
This document provides a series of issues that users ought to keep in mind when configuring their clients after the migration to Office 365.
Estimated time to get Clients fully synced
Every client, of their own respective varying versions and connection protocols (Exchange, IMAP), will take slightly different amounts of time to fully sync up a user's folder structure and mail. The time it takes for a user will also depend on the type of mail they have in their account and the size of their mailbox. This being the case, it is difficult to provide accurate estimates as to how long it will take clients to complete their sync process. It is therefore, only to be regarded as a very general rule of thumb, that a client will take an estimated double the amount of time listed by mailbox size to fully sync. Once the sync has been completed, clients will experience a smoother functionality.
Some points to remember as your account(s) is being migrated:
- Once the migration is started, you will no longer have access to any of your consolidated accounts via any of your previous clients. You will need to either use Outlook on the web or configure a desktop client.
- Do not move messages or make changes to folder structure from within your consolidated account folder area until you receive an email which notifies you that the migration has completed for that specific account.
