off prem to 365

[kevin_lane]

So we have now a hybrid solution for moving our mailboxes from on-prem to off prem

 

I've created a test account and the mailbox and migrated the mailbox last night from on-prem to off-prem and this morning trying to carry on with the testing these are my results

 

 

Migrated [email protected] mailbox > Office 365 = success

 

Tests

 

Email from internal to staffuser = ok

 

Staffuser to internal = ok

 

General school email (all staff emails) still being received = ok

 

My personal email to staffuser = ok (however goes to junk)

 

Staffuser reply to personal email = ok (goes to my main inbox)

 

Ictsupport (internal) email to staffuser = ok

 

Reply to ictsupport from staffuser = error

 

550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient [email protected] not found by SMTP address lookup
