5 Common Issues During Office 365 Migration Errors

Leaping Microsoft Office 365 is more important for organizations of all sizes. After all, O365 makes it easier for employees to collaborate and communicate in the cloud. Additionally, O365 reduces the costs associated with managing costly network and server configurations.

While Office 365 offers countless benefits, many organizations still run into common O365 issues. Let’s check out some of the standard Office 365 migration issues and how these can be resolved.

1. Connection Issues

Exchange Web Service (EWS) needs web (HTTP or HTTPS) access to set a connection between the source and destination services. This service is always open on Office 365 and generally, open on most Microsoft Exchange installations.

With office 365, this is nearly straight forward using https://outlook.office365.com, but the servers, unless office 365 as well, can be a bit more complicated.

A cut and pasted URL can have a space character unexpectedly in front or after it, or a comma instead of a dot are standard forms and can hinder progress while the issue is isolated. Also, user permissions with inadequate or no rights to obtain a mail server can equally slow progress.

We recommend using two ways to make sure you are in the right spot and joining with the correct permissions and therefore decrease time spent with any office 365 migration troubleshooting

a)Logging in to webmail, and creating an email and searching for the required user using the login email id will tell you instantly if the user can be identified. If the user doesn’t show, then and EWS based migration system will not see the mailbox to migrate.

b) Microsoft’s Remote Connection Tool enables you to enter the details of your mailbox server and it will automatically test to make sure that the server is available fully.

2. The Specified Object Was Not Found

Sometimes, the mailbox may have been withheld from the Global Address List. You can check if you have administrator access to the system by checking the “Exchange Advanced “tab within Active Directory Users and Computers.

If you don’t have administrator access, you can verify if the user is hidden by searching within the Global address book from another user account or using outlook or webmail (OWA). If the user is hidden, it will not appear when you search.

This error may also occur if there is a folder containing a backslash \ character. Hence, replacing it would fix the issue.

3. SMTP Address has No Mailbox Associated With It

This issue relates to an error when typing in the username for the mailbox to be migrated most of the time. However, this error can also occur for many other reasons.

If the account is not visible within the address book, then Exchange web services-based migration tools will not recognize the report to be migrated. You can test this by a) logging into webmail (OWA – Outlook Web Access) with a user or administration account, and b) creating a new email and then entering the user’s email id into the “To” field.

If the address determines a current mailbox in the address book, it will display in a provided list which is the correct response. However, if it does not appear in the address book, then it will not be detected.

If using an admin account within office 365, it is possible that a license has not been assigned. As with all office 365 changes, please allow time for any changes to propagate.

4. Server Cannot Service this Request Right Now

When substantial data loads happen, a request can be rejected. This usually happens to protect services such as Office 365 for keeping it safe from overloading. Logging to an Office user as an admin user can increase the number of data loads that can be completed. Also, it is highly recommended that to avoid doing migration during peak hours to reduce the chances of rejection in service requests.

5. Unable to Connect to the Remote Server

While logging in using webmail may not show this error but connecting to the EWS for migration can offer one of these error messages. The common reason for this error is a configured parameter limiting the server from receiving the server’s association or poor performance. But, giving it a go at a different time can be successful while these errors happen. Also, by removing restrictions on the server, these can be solved.
