IMAP Mail Migration
Hello Microsoft Community, We are currently performing a mailbox migration from Google Workspace (Gmail) to Microsoft 365 Exchange Online using the IMAP migration method. The customer's environment is configured for split routing/coexistence, where both Google Workspace and Microsoft 365 are actively being used during the migration process. Mail flow is functioning as expected; however, we are experiencing extremely slow migration performance. For example, a mailbox containing approximately 10 GB of data is taking nearly two weeks to migrate, which is significantly impacting the overall project timeline. We would appreciate guidance on the following: Is this migration speed expected when using the IMAP migration method from Google Workspace to Exchange Online? Does Exchange Online enforce any throttling limits that can affect IMAP migration throughput? Can split routing or coexistence between Google Workspace and Microsoft 365 impact IMAP migration performance? Is there a recommended number of concurrent mailbox migrations or migration batch size for optimal performance? Are there any Google Workspace-side limitations, API restrictions, or throttling settings that should be reviewed? What Microsoft-recommended configurations or best practices can help improve IMAP migration speed? If higher migration throughput is required, does Microsoft recommend an alternative migration approach instead of IMAP? If split routing/coexistence must remain active throughout the migration project, what is the recommended Microsoft-supported migration method? We are trying to identify whether the bottleneck is on the Exchange Online side, Google Workspace side, or related to the coexistence configuration. Any troubleshooting guidance, performance recommendations, or Microsoft documentation references would be greatly appreciated.

Online Archive Not Working for One User
Hi, I am experiencing an issue with the online archive for one of my users. The online archive has been working correctly for this user for years, but it has not archived any emails for the past six months. I have checked the licensing, retention tags, and retention policy, and everything appears to be correctly configured. I have also tried running the Start-ManagedFolderAssistant cmdlet multiple times, but it has not resolved the issue. Other users in my organization have the same retention policy and their online archives are working correctly. I have also tried changing the retention policy for the affected user to one that is known to work for other users, but this did not resolve the issue. I have tried running several cmdlets to gather more information about the issue, including Get-Mailbox | FL RetentionPolicy, Export-MailboxDiagnosticLogs -Identity -ExtendedProperties, Get-RetentionPolicy | FL Name, Get-RetentionPolicyTag, Get-ComplianceTag, Get-Mailbox | fl *hold*, Get-MailboxStatistics | fl ManagedFolderAssistantLastRunTime, Get-Mailbox -Archive | fl *, and Get-MailboxFolderStatistics -Archive | fl *. However, none of these cmdlets have helped me identify the cause of the issue. The output from these cmdlets appears to be normal and does not indicate any issues with the mailbox or the archive mailbox. One thing I noticed is that the Get-MailboxStatistics | fl ManagedFolderAssistantLastRunTime cmdlet does not return any output for any of my users, even though I have run the Start-ManagedFolderAssistant cmdlet multiple times. I am at a loss as to what could be causing this issue and would appreciate any suggestions or guidance on how to troubleshoot it further. Thank you
