Latest Message<\/th>\nTitle: Users recently migrated from Exchange Online to on-premises may be unable to send email messages <\/p>\n

User impact: Users recently migrated from Exchange Online to on-premises may be unable to send email messages. <\/p>\n

More info: Impacted users receive a Non-Delivery Report (NDR) that references a “MaxSendSize” issue.<\/p>\n

In order to correct the issue for currently affected users, admins need to do the following:<\/p>\n

1) In PowerShell connected to Exchange Online, run the command “Get-MailUser -Identity | FT MaxSendSize” and verify that the value is 0.<\/p>\n

2) If the value is 0, then run the command “Set-MailUser -Identity -MaxSendSize Unlimited”, which should allow mail to flow.<\/p>\n

Our fix deployment will only prevent further impact from occurring. The above process is necessary to fully restore mail flow for already affected users.<\/p>\n

Current status: The deployment of the fix has deployed to approximately 97 percent of affected environments. Once fully deployed, we’ll request feedback from affected users to confirm that impact has been fully remediated.<\/p>\n

Scope of impact: Any user that was recently migrated from Exchange Online to on-premises may be unable to send email and may receive a NDR.<\/p>\n

Start time: Tuesday, June 20, 2023, at 12:00 AM UTC<\/p>\n

Root cause: A recent service update that was intending to improve our support of third-party cloud cache quota limits has resulted in impact.<\/p>\n

Next update by: Wednesday, July 19, 2023, at 2:30 PM UTC<\/td>\n<\/tr>\n
