What is a Gmail app password and why do I need it?
An app password consists of a 16-digit code specially created for your Gmail account. This unique passcode allows non-Google applications to connect with your account. Using an app password is an additional security precaution utilised by many applications.
By using the app password, Google and MailJerry can ensure that your data is 100% save and granting access to your account is within your control at all times.
MailJerry says I need to enable IMAP for Gmail. How do I do this?
1. To enable IMAP for your Gmail account, go to https://mail.google.com and click on the settings icon (gear icon in the top right corner). Here, click on „See all settings“.
2. Click on the tab „Forwarding and POP / IMAP“ and scroll down to „IMAP access“.
3. Here, click on the option „Enable IMAP“.
➡️ Don’t forget to save your changes by scrolling down to the bottom of the page and clicking on „Save settings“.
My migration from Gmail to Office 365 is very slow! What can I do?
Unfortunately, Google applies bandwidth limits (max. 2500 MB of downloaded data per day). This means, after migrating 2500 MB, your migration will run significantly slower and take more time.
But don’t worry! Do not stop the email migration. It is absolutely no problem when your migration runs longer than 24 hours. In fact, we already migrated very (very) large mailboxes that took more than two weeks without any problems!
I’m im a hurry. Is there any chance to speed up the migration?
If you’re in a hurry and run into Google’s bandwith limits, you can do the following:
1. Stop your current migration (don’t worry, you won’t loose any progress you made so far).
2. Start the migration again as described in this tutorial, but enable the option “Ignore Google Bandwidth Limits”.
With this option enabled, MailJerry ignores Googles bandwith limits and tries to migrate your email data as quickly as possible.
Only downside: It’s possible that you’ll get disconnected by Google during the migration. If this happens, you have to start the migration again, this time without enabling “ignore bandwidth limits”. Since you won’t loose any progress you made until your migration broke, it’s worth a try!
Not all emails where migrated, what can I do?
When migrating large emails to Office 365, it is possible that emails larger than 25 MB are rejected due to Microsoft’s maximum message size limit. To change the max message size, follow this tutorial.
After changing the maximum message size, enable the auto sync or click on the “Sync Now” button. MailJerry will now migrate the skipped emails as well.
I’ve assigned multiple labels to one email. What happens after the migration to Office 365?
When migrating from Gmail to Office 365, Gmail labels are converted to folders. The email containing multiple labels is then moved to the folder that represents the first label the message was originally assigned to.
If you’d like to re-build the same folder structure as in Gmail (= the same email is contained in both folders a.k.a labels), you can do so before starting the migration on the summary page: Simply enable the option “Migrate Duplicates”. By doing so, MailJerry will create copies of your message and move a copy in every folder that represents the former labels.
Example: Your message has the labels “Important” and “My Label”. When enabling duplicates, your message is moved to the folder “Important” AND a copy of the message is created and moved into the folder “My Label”.
Can I close MailJerry during the email migration?
Yes. Migrating large mailboxes from Gmail to Office 365 might take some time. Since your data is directly migrated between Gmail and Office 365, you can close the MailJerry software at any given time and even shut down your computer, without loosing any data / migration progress!
